1 00:00:00,540 --> 00:00:03,750 I say to them that you need to turn that off. 2 00:00:04,620 --> 00:00:09,180 So can you just, first of all, say your name and your current title? 3 00:00:09,930 --> 00:00:19,500 Yep. So my name is Thomas Kirk and I am now a research fellow at the University of Nottingham in biomedical engineering, specifically imaging. 4 00:00:20,340 --> 00:00:29,010 Terrific. Thanks very much. So without telling me every minute of your life story, can you just give me the headlines on your your career so far, 5 00:00:29,010 --> 00:00:37,350 starting really from how you first became interested in And I don't know whether the life sciences or the engineering side of it came first, 6 00:00:37,350 --> 00:00:48,299 but in those subjects. So I was I was always interested in engineering from from a relatively young age, 7 00:00:48,300 --> 00:00:54,270 but not interested in the sense that I knew from a long way out, I want to go to university and I want to be an engineer. 8 00:00:54,600 --> 00:00:58,110 I know some kids have not quite well formed life plan. 9 00:00:59,070 --> 00:01:04,530 That wasn't the case for me. However, when it came down to applying for university, 10 00:01:05,430 --> 00:01:11,430 I was at a very good school where pretty much everyone goes to university, so I was just going with the flow, as it were. 11 00:01:12,060 --> 00:01:20,130 And but that's the that was the first time where I seriously considered that I could go to Oxford or Cambridge, and now I had the grades to do that. 12 00:01:21,270 --> 00:01:28,649 I applied to Cambridge and again, actually I failed by interview and then I spent a year working as a maths teacher on 13 00:01:28,650 --> 00:01:36,389 a teach first scheme and then I reapplied fogs at this time and did much better. 14 00:01:36,390 --> 00:01:44,459 And I think the teaching experience I was doing probably helped a lot because my the interviewer at Trinity College, 15 00:01:44,460 --> 00:01:51,900 where I played in Oxford, his wife is a teacher, so we did spend part of the interview talking about the challenges of teaching. 16 00:01:51,900 --> 00:01:55,790 And I think that that probably helped put me at even. Anyway. 17 00:01:56,180 --> 00:02:02,239 And Oxford is a is a special place to do engineering in the UK like Cambridge. 18 00:02:02,240 --> 00:02:10,070 But not many other universities share this property of offering a general engineering course where you specialise as you go on. 19 00:02:11,660 --> 00:02:15,530 And initially biomedical didn't feature on my radar at all. 20 00:02:16,130 --> 00:02:22,290 I thought I'd probably end up as a civil engineer and then after having done one year of general engineering at Oxford, 21 00:02:22,290 --> 00:02:31,130 realised I absolutely hated civil engineering engineering, I ended up quite liking electrical, which I never thought would happen. 22 00:02:32,150 --> 00:02:42,559 And then that was the influence of one tutor in particular called Michael Chappell, who I remain working with now at Nottingham. 23 00:02:42,560 --> 00:02:45,740 He supervised my PhD and now I work with him at Nottingham. 24 00:02:47,420 --> 00:02:53,270 He is the person that steered me towards biomedical engineering as I went through my degree. 25 00:02:53,960 --> 00:03:01,640 So in second year he started tutoring me for control and then he supervised me on a small summer 26 00:03:01,640 --> 00:03:06,680 project in third year and then he supervised me for my Masters Year project in fourth year. 27 00:03:07,010 --> 00:03:12,139 And then he invited me to apply for a PhD with him and so on and so on. 28 00:03:12,140 --> 00:03:15,530 And here we are eight years later, and I'm still working with with Michael. 29 00:03:16,160 --> 00:03:21,590 And the subject to be the subject of my PhD is. 30 00:03:22,040 --> 00:03:30,380 So we work in the field of MRI imaging, which is a particular strong point of Oxford, particularly for the brain. 31 00:03:31,490 --> 00:03:41,000 And my Ph.D. was working with new types of MRI, in particular one called arterial spin labelling. 32 00:03:42,730 --> 00:03:53,530 And it's it's a very promising modality for investigating the function of the brain and moving towards neurodegenerative disease. 33 00:03:54,310 --> 00:04:03,520 And this is because it's measuring entirely different properties of the brain compared to conventional MRI imaging. 34 00:04:03,790 --> 00:04:09,550 So the image that you get out of the brain is very different. It tells you very different things compared to a normal MRI. 35 00:04:10,000 --> 00:04:15,250 But it is a it is an image rather than a spectrum that you then it remains an image. 36 00:04:15,330 --> 00:04:18,670 Yeah. The challenge is it's very noisy. 37 00:04:19,600 --> 00:04:24,000 I mean, you get very low quality, very blocky, grainy, noisy images. 38 00:04:24,640 --> 00:04:35,530 And therefore to get around that, you need to use sophisticated mathematics, in particular a framework called the variation or Bayesian framework. 39 00:04:36,370 --> 00:04:46,540 And so that was the crux of my Ph.D. is applying variational Bayes to arterials and labelling MRI to improve the image quality that you get. 40 00:04:46,960 --> 00:04:48,860 And here's a challenge for your teaching skills. 41 00:04:48,880 --> 00:04:56,230 Is it possible to explain very simple Bayesian approaches in a way that somebody who doesn't have the maps would understand? 42 00:04:57,910 --> 00:05:01,940 Yeah, it is, actually. It's an. How would you do it? 43 00:05:02,300 --> 00:05:08,700 So. So the crux of Variational Bayes is. 44 00:05:10,650 --> 00:05:25,110 There are good theoretical reasons why a Bayesian approach is the best strategy to use for this problem and for the problems of that statistic. 45 00:05:25,110 --> 00:05:31,229 Piece of statistical terminology. How exactly guilty Bayesian stands in contrast to. 46 00:05:31,230 --> 00:05:34,580 I might be scrambling my terminology here, 47 00:05:34,860 --> 00:05:43,380 but it stands in contrast to likelihood based approaches so that generally people will adopt a maximum likelihood approach. 48 00:05:44,640 --> 00:05:48,780 And a Bayesian approach is is similar. 49 00:05:48,780 --> 00:05:56,730 There's a subtle difference, but in certain circumstances, a Bayesian approach ends up being the same as a as a maximum likelihood approach. 50 00:05:57,090 --> 00:06:02,040 The difference is the Bayesian approach allows you to incorporate prior knowledge. 51 00:06:02,370 --> 00:06:11,880 So before you've even image to the patient, there are certain things that we know to be true about what answer will come back. 52 00:06:12,270 --> 00:06:20,970 And in particular outside of MRI measures, blood flow in the brain, we measure the rates of delivery of blood to different regions in the brain. 53 00:06:21,900 --> 00:06:26,190 And therefore we know ahead of time that these values will never be negative. 54 00:06:27,210 --> 00:06:31,410 And they could be zero. For example, a stroke would be an occlusion. 55 00:06:31,410 --> 00:06:36,210 So therefore some regions of the brain would have zero flow, but they will never be negative. 56 00:06:36,510 --> 00:06:41,850 And so you have this kind of private information of what is plausible from physiology. 57 00:06:43,140 --> 00:06:52,080 And when you incorporate the this prior knowledge into the Bayesian framework, you will end up with answers. 58 00:06:52,080 --> 00:06:56,740 That's a different. I knew you would obtain a few. 59 00:06:57,470 --> 00:07:01,370 And if you didn't adopt the Bayesian approach. 60 00:07:01,390 --> 00:07:09,220 If you use a likelihood based approach, what you're trying to achieve is some level of certainty about what you're looking at on the image. 61 00:07:09,730 --> 00:07:16,150 Hmm. Or in fact, actually, you you qualitatively, you are correct. 62 00:07:16,840 --> 00:07:21,460 But one of the really neat things about a Bayesian approach is not only does it give you 63 00:07:21,610 --> 00:07:25,840 the estimates of the things you're looking for and allows you to quantify uncertainty. 64 00:07:26,860 --> 00:07:34,750 So in the case of a particularly poor image, you might come back with an answer that says, okay, we believe the blood flow to be this value. 65 00:07:35,140 --> 00:07:37,600 But the uncertainty on that is very wide, actually. 66 00:07:38,020 --> 00:07:45,250 And that's the the maths telling you this was a very good acquisition, whereas in other cases you'll get a very tight uncertainty. 67 00:07:45,830 --> 00:07:56,650 So that's also quite a nice property of it. So you were working away on this Dphil very worthwhile, useful thing to be doing. 68 00:07:57,460 --> 00:08:04,660 And then at some point you will have heard that there was something going on in Wukan. 69 00:08:04,870 --> 00:08:13,989 Can you remember I'm asking everybody this. Can you remember when you first heard about the outbreak of of COVID in Wuhan, 70 00:08:13,990 --> 00:08:23,140 and how long was it before it became apparent to your group that actually this was something that you could jump in and and contribute to? 71 00:08:23,980 --> 00:08:30,020 So. Now I can remember very well Christmas 2019, reading about it. 72 00:08:31,370 --> 00:08:36,320 But even before that, actually, there's something interesting happened. 73 00:08:36,500 --> 00:08:43,520 To this day, I do not have an explanation for. I was in Shanghai late November 2019. 74 00:08:43,820 --> 00:08:50,810 Oh, really? Yeah. And I flew back with another Oxford Ph.D., actually. 75 00:08:51,560 --> 00:08:58,610 And we we flew back to the UK, and I've only ever flown to the Far East. 76 00:08:58,610 --> 00:09:01,960 That entire region of the world. I've only ever flown there once, which was this trip. 77 00:09:01,970 --> 00:09:07,460 So I don't know if this is normal, but I'm told it's not normal. On the way back home, it was a British Airways flight. 78 00:09:08,300 --> 00:09:16,910 At one point the cabin was sprayed down with a mist and all of the flight attendants put on respirators and masks, 79 00:09:17,390 --> 00:09:21,740 but they didn't give us any notice of what was about to happen. They didn't give us any masks. 80 00:09:21,740 --> 00:09:25,730 And then for about 20 seconds, the entire cabin was sprayed down with something. 81 00:09:26,480 --> 00:09:33,410 And at the time, I assumed it was some sort of infection control, pest control measure. 82 00:09:34,220 --> 00:09:39,020 Never has it been explained. I'm led to believe it's not exactly common on flights. 83 00:09:39,020 --> 00:09:41,990 I've done a couple of long distance flights from the US, and that hasn't happened. 84 00:09:42,320 --> 00:09:50,960 And we now know in hindsight that the first confirmed case in Shanghai was a few days after we left Shanghai. 85 00:09:51,200 --> 00:09:55,010 Actually, they've managed to date the first COVID case in Shanghai. It's just afterwards. 86 00:09:55,520 --> 00:10:02,600 So for all we know, while we were there, it already started spreading around South Korea spread. 87 00:10:03,470 --> 00:10:08,780 And then when when it started gathering pace in the UK. 88 00:10:11,490 --> 00:10:15,390 We never once did we discuss as a group whether we could contribute. 89 00:10:16,290 --> 00:10:20,969 It's not really that's not really the way my group operates. 90 00:10:20,970 --> 00:10:24,840 We're a computational group. We deal with quite hardcore imaging. 91 00:10:25,710 --> 00:10:29,340 In particular, MRI is not going to be used in a COVID context. 92 00:10:30,300 --> 00:10:38,970 It would never be used in an emergency situation. The doctors would always reach for X-ray C.T., things like that that are much quicker to operate. 93 00:10:39,870 --> 00:10:44,660 And however, as it was becoming increasingly clear there would be a lockdown, 94 00:10:44,670 --> 00:10:50,040 I did email the Jenner Institute, who were working in the floor above me. 95 00:10:50,490 --> 00:10:53,640 I was based at the Old Road campus and the IBM, 96 00:10:54,420 --> 00:10:59,610 so I emailed the Jenner Institute and said I'd be happy to help out for data analysis 97 00:11:00,300 --> 00:11:04,050 because I presumed at some point they would have reams of data to be crunching through. 98 00:11:04,830 --> 00:11:10,530 So they said they would bear the offer in mind and they added it to a list. 99 00:11:10,530 --> 00:11:14,819 I believe they had a list of people who'd offered likewise and said, We'll get in touch if we need you. 100 00:11:14,820 --> 00:11:19,860 But that never did happen. And then very soon after I made that offer. 101 00:11:19,860 --> 00:11:23,790 Anyway, Oxfam's came in to my my path. 102 00:11:24,870 --> 00:11:27,540 Right. So let's tell that story. So what? 103 00:11:30,810 --> 00:11:39,459 Clearly, after looking at what happened in Italy, there was always concern in the UK about hospitals being overwhelmed, 104 00:11:39,460 --> 00:11:45,450 a shortage of beds, shortage of personnel and and also, crucially, crucially, shortage of ventilators. 105 00:11:46,320 --> 00:11:53,760 So how did colleagues of yours come to think that that was an area where they could make a contribution? 106 00:11:55,080 --> 00:11:58,650 Are you on Twitter, by any chance? Yes. Yeah, I'm not. 107 00:12:00,780 --> 00:12:06,749 Medical Twitter is is a very active subset of Twitter and medical. 108 00:12:06,750 --> 00:12:10,290 Twitter, I believe, plays an important role in this question. 109 00:12:10,620 --> 00:12:18,390 So the the person who really kicked off her was Robert Starrett, who is also a PhD. 110 00:12:18,600 --> 00:12:24,750 He's is just about finishing his Ph.D. now, actually, and he's also a military medic. 111 00:12:25,740 --> 00:12:30,000 Do you know any background about Robert or I did wait up a little bit about him as well. 112 00:12:30,000 --> 00:12:38,850 Yes. So. So it was it was him who was looking at the news coming out of Italy. 113 00:12:39,750 --> 00:12:47,130 And in particular, he's very active on Twitter and he's he's plugged into all the communities of health care, people on Twitter and. 114 00:12:48,520 --> 00:12:55,510 It is my understanding he was the first person to join the dots and think this is going to hit the UK like it like a train. 115 00:12:55,780 --> 00:13:02,740 This is going to be really, really bad. And so he started thinking about emergency ventilation. 116 00:13:03,460 --> 00:13:07,690 And then I believe the next person he approached was Andrew Farmer. 117 00:13:09,570 --> 00:13:22,740 Within anaesthetics. Yes. Correct. And Rob's wife and their stroke is a she's an a niece anaesthetist who works in intensive care as well. 118 00:13:23,250 --> 00:13:26,480 So I believe she might have made the introduction. 119 00:13:26,490 --> 00:13:27,550 I'm not sure on that. 120 00:13:27,570 --> 00:13:37,170 But either way, Rob has this background in plastics and surgery and that his wife has the background in intensive care and certainly is more, 121 00:13:37,470 --> 00:13:45,330 more familiar with that part of the medical world. And very soon after Rob started having these ideas, he was put in touch with Andrew Farmer, 122 00:13:46,080 --> 00:13:55,200 I believe Andrew Farmer being the kind of person he is, which is to say is a wonderful free thinker. 123 00:13:55,350 --> 00:13:59,610 Actually, he's he's an excellent person to to work with. 124 00:13:59,610 --> 00:14:08,880 It's really good fun interacting with him. And because he he is just a curious experimental type of person, which is thrilling to be around. 125 00:14:09,720 --> 00:14:13,620 So I suspect he was already having many of the same ideas anyway. 126 00:14:14,460 --> 00:14:19,260 And then between the pair of them and my understanding is that a. 127 00:14:20,410 --> 00:14:26,560 They quickly built a prototype and they looked at a few other people to this effort. 128 00:14:27,250 --> 00:14:33,490 And then the prototype itself was assembled by the engineering workshop at the IBMA. 129 00:14:35,480 --> 00:14:42,110 And particularly the two technicians whose names I'm struggling to remember right now. 130 00:14:42,210 --> 00:14:44,600 I can pull them up later, if that would be important. 131 00:14:46,640 --> 00:14:52,880 And what was the what was the I mean, clearly there are designs of ventilator that are out there already. 132 00:14:53,330 --> 00:14:56,540 What were the advantages of this? Of the oxidant? 133 00:14:56,960 --> 00:15:04,130 What became the oxidant? What was what were they kind of new challenges that it was trying to solve? 134 00:15:05,200 --> 00:15:13,070 That's a good question. So I. Cheap and simple above all else is the is the mantra. 135 00:15:13,490 --> 00:15:16,670 I presume that was the guiding principle from the off. 136 00:15:17,420 --> 00:15:23,960 Cheap and simple. And the initial vision was that we would. 137 00:15:24,680 --> 00:15:32,030 I was involved in the project at this point, but it would be designed and then the design would be open sourced and then it could 138 00:15:32,030 --> 00:15:37,280 be assembled by anyone around the country who had a sufficiently equipped workshop. 139 00:15:37,910 --> 00:15:42,320 And in particular they were thinking university workshops could probably channel these out, 140 00:15:43,340 --> 00:15:54,950 which is why the two technicians at the IBM Me workshop, who are magicians, they have a long history of creating incredible apparatus. 141 00:15:55,360 --> 00:15:59,120 It is why they were such a crucial part of this early effort. 142 00:16:00,110 --> 00:16:02,899 And so the idea was that using their practical knowledge, 143 00:16:02,900 --> 00:16:07,250 they could refine the design and then you chair anyone could start manufacturing from that point. 144 00:16:07,970 --> 00:16:10,820 So it was simplicity all the way. 145 00:16:11,390 --> 00:16:20,690 And around this time, news must obviously have been spreading internally within Oxford that some people were working on this project. 146 00:16:21,790 --> 00:16:30,800 And then the next key persons come on board, in my recollection is Harrison. 147 00:16:30,820 --> 00:16:38,830 Harrison Steele is called and Harrison is now an associate professor at the Department of Engineering. 148 00:16:38,830 --> 00:16:42,380 He was not at the time. I don't believe he is another surgeon. 149 00:16:42,460 --> 00:16:50,350 These people, he's he's a genius. And Harrison is probably the most capable individual on the entire project. 150 00:16:50,890 --> 00:16:54,250 He really is operating at a level above everyone else. 151 00:16:55,420 --> 00:17:00,390 And he. His expertise in controlling electronics. 152 00:17:01,170 --> 00:17:10,860 And he approached Rob and Andrew Farmer and basically said, I will take care of whatever electronics and control is required for this, 153 00:17:11,400 --> 00:17:18,780 and to which I think their response was along the lines of that's actually we hadn't really thought anything on that topic. 154 00:17:19,860 --> 00:17:25,200 So if you're willing to just take care of that, that's great because that is not something they are familiar with. 155 00:17:26,300 --> 00:17:31,190 And then my involvement at this point, I think I've been at home for. 156 00:17:32,260 --> 00:17:43,180 Four or five days. The start of lockdown. And then, yeah, my involvement came in because I had previously imagined that's his name. 157 00:17:44,090 --> 00:17:48,440 I had previously worked with Jim, the technician at the IBM workshop. 158 00:17:48,460 --> 00:17:55,450 I'd done a few projects with him and I was once again, I don't know how Rob came to learn this, 159 00:17:55,450 --> 00:18:05,620 but basically my name was thrown out as someone who would be a safe pair of hands to liaise with Jim because like many workshop technicians, 160 00:18:05,620 --> 00:18:13,550 the world over and. There's a certain way of dealing with the people who own the workshop. 161 00:18:13,970 --> 00:18:20,810 And in particular, at this point, the project was gaining momentum and lots of people were just agglomerated around the nucleus of the project, 162 00:18:21,290 --> 00:18:29,570 but they were all congregating in the workshop. And so there were, you know, a dozen or two dozen people floating around the workshop, 163 00:18:29,690 --> 00:18:38,030 getting in the way of the technicians and just generally asking difficult questions and not not being, 164 00:18:38,150 --> 00:18:41,809 let's say, linearly minded in the way the workshop. 165 00:18:41,810 --> 00:18:49,070 People like to be very linearly minded. And so my role, Rob approached me to basically say, look, 166 00:18:49,070 --> 00:18:56,330 I need to get everyone out of the workshop and I need them to stop asking silly questions to the technicians. 167 00:18:56,690 --> 00:19:04,099 And I need someone to be the liaison between the ideas people and the workshop people, 168 00:19:04,100 --> 00:19:08,270 someone who can speak the right language to them and just insulate them from all the chaos. 169 00:19:09,380 --> 00:19:13,450 And that was my role initially. Mm hmm. 170 00:19:13,880 --> 00:19:21,380 I just wanted to say. Yeah. And you weren't the only graduate student involved in this project. 171 00:19:21,410 --> 00:19:26,840 Oh, no. Very much. No. Yeah, Lots of others accumulated. 172 00:19:27,260 --> 00:19:31,520 I'm happy to say quite a big chunk of them were Trinity. 173 00:19:31,670 --> 00:19:35,390 As it happens at this point, I am now maudlin. 174 00:19:36,200 --> 00:19:39,770 As a PhD student, I went over to modelling college, and that's where Rob was. 175 00:19:40,550 --> 00:19:47,510 But by sheer coincidence, a lot of the key foods happened to be Trinity, 176 00:19:49,010 --> 00:19:57,800 including the the student Andrew, or who was on the news report, which I hope is now in the archives. 177 00:19:59,240 --> 00:20:04,040 When Sky News came in to film the prototype operating the ventilator, 178 00:20:04,640 --> 00:20:14,180 it was Andrew or who was put forward as our representative to demonstrate the prototype working, and he started receiving fan mail. 179 00:20:14,300 --> 00:20:21,710 I believe the various people managed to track him down and he received quite a lot of emails. 180 00:20:22,880 --> 00:20:28,310 So see, I hope that piece of footage can be located and put in the archives is very entertaining. 181 00:20:29,480 --> 00:20:33,110 So what was the how was the prototype being demonstrated? 182 00:20:33,110 --> 00:20:36,680 So at this stage it hadn't actually been used on a on a patient, presumably. 183 00:20:36,920 --> 00:20:43,030 No. And. To my knowledge, I don't think it ever was. 184 00:20:43,700 --> 00:20:54,400 Yeah, at no stage. And the closest they got was either dummy patients or I'm not sure that's the correct term for it. 185 00:20:58,990 --> 00:21:06,030 Now at this stage it was operating on an iron lung or a rubber lung, rather, 186 00:21:07,290 --> 00:21:14,140 which is an ancient piece of apparatus that is covered in rust, but I believe dates from the fifties or sixties. 187 00:21:14,520 --> 00:21:18,669 You'd have to ask an Andrew summary. It's my understanding, Andrew Farmer, 188 00:21:18,670 --> 00:21:25,550 he has a collection of eclectic equipment and apparatus that should probably have been on the scrap heap a long time ago. 189 00:21:25,560 --> 00:21:29,130 But he's here in the museum. Yeah, exactly. 190 00:21:29,580 --> 00:21:32,960 And that he's somehow, you know, saved from the scrap heap. 191 00:21:32,970 --> 00:21:37,590 So we were using this and yeah, it demonstrates the principles. 192 00:21:39,630 --> 00:21:45,930 Which. Which are simply we should you know, I've been kind of assuming making assumptions that people would know what we're talking about. 193 00:21:45,930 --> 00:21:51,330 But it it delivers oxygen to a patient who's not able to breathe for themselves. 194 00:21:51,420 --> 00:22:00,000 Yeah. Yeah, well, no. Good point. So a crash course in ventilation and so. 195 00:22:01,900 --> 00:22:05,440 Yeah, I actually just delivers air. That's the main thing. 196 00:22:06,040 --> 00:22:13,720 It is compensating for the patient's inability to breathe in sufficiently under their own power. 197 00:22:15,610 --> 00:22:18,970 It is common that you will also enrich it with oxygen. 198 00:22:20,430 --> 00:22:27,780 But you probably wouldn't do pure oxygen and that would be a quite severe case if they were on pure oxygen. 199 00:22:28,140 --> 00:22:34,950 I think for COVID, most of the time you could, you know, they just needed help breathing with a slightly enriched mix. 200 00:22:35,920 --> 00:22:47,520 And there are different modes of ventilation. So the way our one operated is the most basic and called a volume controlled ventilator. 201 00:22:47,970 --> 00:22:53,010 So the operator would set a specific volume of air. 202 00:22:54,060 --> 00:23:00,990 Fernando, This will be about 400 millilitres and the ventilator will provide 400 millilitres 203 00:23:00,990 --> 00:23:07,800 in one go at a certain frequency and the patient just has to get with it. 204 00:23:08,070 --> 00:23:15,210 Here the patient has to sync themselves up with the right cause because the ventilator will do it no matter what. 205 00:23:15,240 --> 00:23:20,570 It will deliver that 400 at that frequency. And there are more sophisticated modes. 206 00:23:20,580 --> 00:23:25,440 So there is a mode that's called and pressure controlled, 207 00:23:25,440 --> 00:23:34,709 and that's where the ventilator will provide the access sets and pressure, whereas in volume controlled, 208 00:23:34,710 --> 00:23:43,320 the ventilator will basically provide that's not volume 400 millilitres, whatever pressure is necessary to get it in up to a certain point. 209 00:23:43,710 --> 00:23:52,350 And the reason why pressure becomes so important is because in acute respiratory distress syndrome, AIDS, 210 00:23:52,740 --> 00:24:02,760 which is the the and the state in which COVID patients end up in when they have difficulty breathing. 211 00:24:02,760 --> 00:24:06,060 That was called ARDS respiratory distress syndrome. 212 00:24:06,600 --> 00:24:12,330 And I believe there's there's a stiffening of the the respiratory organs. 213 00:24:13,800 --> 00:24:18,810 And so to to inhale the same volume of air, 214 00:24:18,900 --> 00:24:28,230 a much greater force is required from the patient because that their membranes and the lungs themselves have become stiffer because of this syndrome. 215 00:24:28,590 --> 00:24:33,810 And so that's why the pressure's required to achieve the same volume might change during ARDS. 216 00:24:34,230 --> 00:24:35,520 And then finally, the. 217 00:24:36,440 --> 00:24:45,830 And the most sophisticated forms of ventilation will entirely remember how they work, to be honest, because it's not not at all my background. 218 00:24:46,180 --> 00:24:57,309 And I suppose the key takeaway here is to note that the the ventilator was designed to capture 219 00:24:57,310 --> 00:25:05,390 the the most basic end of the spectrum of patients that might plausibly be puts on it. 220 00:25:05,990 --> 00:25:12,080 It was never designed to be a comprehensive ventilator that could handle every situation that was thrown into it. 221 00:25:12,500 --> 00:25:19,760 It was designed to be a ventilator that could handle 80% of the bottom 80% of cases, 222 00:25:19,760 --> 00:25:26,960 the simple ones, and therefore the top 20%, a complex that would require very advanced ventilation. 223 00:25:27,620 --> 00:25:35,240 You'd be able to put them on the existing high standard ventilators and free up the capacity, basically. 224 00:25:35,750 --> 00:25:41,900 So this was it was a deliberately simple design, and we knew that it would never be able to take care of all situations. 225 00:25:43,200 --> 00:25:47,140 But the idea was that it would be implemented during this pandemic. 226 00:25:47,160 --> 00:25:51,150 I mean, there was there was an urgency about developing it. 227 00:25:51,570 --> 00:25:58,410 Absolutely. So. So this now leads into phase two of the project, the the ventilator challenge. 228 00:25:59,130 --> 00:26:03,830 Does that ring any bells? It's yes, it's beginning to. 229 00:26:03,840 --> 00:26:10,049 But talk me through it. So for posterity, for the future, people listening. 230 00:26:10,050 --> 00:26:18,780 I will also say at this point that there was a lot of media coverage around the ventilator challenge and in particular towards the end of it, 231 00:26:19,290 --> 00:26:23,430 I believe this would have been April, May, June of 2020. 232 00:26:24,090 --> 00:26:36,240 And the Financial Times published quite a thorough investigation of behind the scenes in the Investigates ventilator challenge and. 233 00:26:37,270 --> 00:26:47,830 To my knowledge, that was a very well resourced story because they were reporting things that I we knew to be true but were very much secret. 234 00:26:48,040 --> 00:26:51,790 And B, they then reported a whole lot of things that we have no idea about ourselves. 235 00:26:52,510 --> 00:26:59,409 So so for anyone looking in the future to, to understand the background to that F.T. article, 236 00:26:59,410 --> 00:27:02,620 I don't know the name of the journalist, unfortunately, but it was very well resourced. 237 00:27:03,690 --> 00:27:11,940 So I'm. So this was a this was a challenge that was thrown out by the government, was it to develop the. 238 00:27:11,940 --> 00:27:18,089 Correct. So so coming late, late February, early March, 239 00:27:18,090 --> 00:27:25,620 I'm not entirely sure the state of play was that in Oxford we had put together a benchtop prototype that was operating. 240 00:27:28,610 --> 00:27:35,809 Very basic ventilator and we were thinking we could share it around the country and people could crank out a few hundred at a time. 241 00:27:35,810 --> 00:27:38,480 And it would all be part of this wonderful grassroots effort. 242 00:27:39,290 --> 00:27:50,000 And lots of other people had come up with similar ideas and in particular after after he went on Sky News. 243 00:27:51,690 --> 00:27:56,969 And other people who'd had similar ideas started sending their ideas to us and saying, 244 00:27:56,970 --> 00:28:01,670 Oh, maybe you could incorporate this, this and this, which was very nice. 245 00:28:01,680 --> 00:28:06,570 But we ourselves, we didn't really have the capability to do anything with those ideas. 246 00:28:07,770 --> 00:28:11,190 We weren't able to start manufacturing in large quantities ourselves. 247 00:28:12,450 --> 00:28:14,309 And this is where the ventilator challenge came in. 248 00:28:14,310 --> 00:28:25,170 So the government decided to launch this challenge and they called up all industry in academia to to respond to the ventilator challenge. 249 00:28:25,860 --> 00:28:34,710 And they set out a specification. It was called the AR and the document, the rapidly manufactured ventilator specification. 250 00:28:35,920 --> 00:28:41,890 And that sets out the requirements for a basic ventilator device. 251 00:28:42,490 --> 00:28:50,190 They must provide at least this volume, at least this respiratory rate, and must operate for this length of time, etc., etc. 252 00:28:51,460 --> 00:29:02,970 And then. Teams were called to basically submit their prototype designs to me, that specification, and then that would be a shortlisting stage. 253 00:29:04,130 --> 00:29:13,040 And then that was a preparation for manufacture stage where ideas were assigned to to other. 254 00:29:14,640 --> 00:29:22,709 Other companies who could help accelerate them. And I'm not really sure of all the the logistics anymore in anyway. 255 00:29:22,710 --> 00:29:30,810 It doesn't really matter because the the whole thing constantly kept changing in motion anyway because it was such a stressed, rushed situation. 256 00:29:31,560 --> 00:29:37,350 So I, I believe Oxford wasn't originally on the shortlist to go through, 257 00:29:37,350 --> 00:29:42,630 but then after the Sky News report, I believe we were added to the shortlist at the last minute. 258 00:29:43,410 --> 00:29:48,150 At this point I was still only vaguely involved in the project, so that's why I'm not entirely certain. 259 00:29:50,880 --> 00:30:00,060 And then once we were on the shortlist, what then happened is Smith and Nephew take a medical manufacturing firm in the UK. 260 00:30:00,630 --> 00:30:08,820 They had submitted their own idea to the ventilator challenge that was not shortlisted. 261 00:30:09,570 --> 00:30:11,670 I can't remember the principles. 262 00:30:11,670 --> 00:30:19,860 I think that has worked on negative pressure, which is logical for Smith and Nephew because they're their main product. 263 00:30:19,860 --> 00:30:25,020 The thing that generates most of their revenue is it's called negative pressure therapy for wounds. 264 00:30:25,950 --> 00:30:35,640 And it's a it's a way of keeping serious wounds clear while they heal and it dramatically reduces reinfection, etc. 265 00:30:36,240 --> 00:30:39,299 So they've already mastered that technology for wound healing. 266 00:30:39,300 --> 00:30:42,900 So it's quite logical that they approach ventilation in a similar manner. 267 00:30:43,500 --> 00:30:47,960 And so Smith and Nephew had put that design forward. 268 00:30:47,970 --> 00:30:53,640 It wasn't shortlisted and so they were then match made with us by the government, the powers that be. 269 00:30:55,420 --> 00:31:01,139 So now the situation was we Oxford and King's College, London. 270 00:31:01,140 --> 00:31:04,890 They were at this point a load of anaesthetists and intensive care. 271 00:31:04,890 --> 00:31:08,820 People had come on board from King's College London. 272 00:31:10,150 --> 00:31:15,370 We were matched up with Smith and Nephew to prepare the design for manufacturing. 273 00:31:15,820 --> 00:31:21,990 And so around this time. Eight of us were. 274 00:31:22,990 --> 00:31:32,740 We went drove up from Oxford to Hull, which is where Smith and nephew have their main UK manufacturing facility. 275 00:31:33,550 --> 00:31:38,410 And yeah, we moved up there to prepare for the next phase of the project. 276 00:31:38,410 --> 00:31:42,690 And your role was going to change then? 277 00:31:42,700 --> 00:31:45,970 At this point you were no longer simply the gatekeeper of the workshop. You were. 278 00:31:46,450 --> 00:31:56,589 Yeah. Yeah. So at this point I was Tim Dennison, who was one of the professors at the Oxford end of things, 279 00:31:56,590 --> 00:32:00,100 who has a lot of experience and regulatory side of things. 280 00:32:00,970 --> 00:32:05,740 He used to work in industry at Medtronic, which is a huge American medical devices fund. 281 00:32:06,880 --> 00:32:12,310 He was taking on more of the sort of regulatory strategic direction of the project. 282 00:32:13,900 --> 00:32:19,180 Yeah, I was never officially assigned a role, but Tim Dennison described me as systems integration lead. 283 00:32:19,750 --> 00:32:22,960 Yes, I saw that. I saw that phrase. And I was going to ask you what it meant. 284 00:32:23,420 --> 00:32:33,700 Yeah. So it systems integration is, you know, a little bit about everything and you make sure that it all fuses together. 285 00:32:34,330 --> 00:32:40,120 So, you know a little bit about the control system, you know a little bit about the manufacturing side of things, 286 00:32:40,120 --> 00:32:43,150 you know a little bit about the battery, the power, the sensors. 287 00:32:43,750 --> 00:32:48,820 And your responsibility is to make sure everything matches up nicely. 288 00:32:51,080 --> 00:32:54,620 So yeah, that's a very big responsibility, isn't it? 289 00:32:55,400 --> 00:33:04,250 Yeah. Yeah, it is. And yeah, so I was I mean, I was quite pleased with that because I'm, I am a generalist. 290 00:33:04,250 --> 00:33:08,980 I think that is, that is what I do best. So I thought it seems to me quite well. 291 00:33:08,990 --> 00:33:17,270 But, and though that was the title that someone used to describe what I was doing, it was always very flexible. 292 00:33:17,330 --> 00:33:24,140 Anyway, we didn't really ever have much time to sit down rigidly, define who was doing what with I. 293 00:33:24,470 --> 00:33:27,620 You know, if we were doing things again, that would probably be a good thing to do. 294 00:33:28,280 --> 00:33:37,000 But it was more to do with. Interpersonal relations management, then you weren't actually doing computation. 295 00:33:37,360 --> 00:33:43,190 You weren't doing this. You weren't deploying your skills in maths and computation on this project yourself? 296 00:33:44,390 --> 00:33:52,130 No. A lot of the time there were parts where I did need to do some certain maths, in particular around calibration, 297 00:33:52,730 --> 00:33:56,570 so that that would be the most technical contribution I made was around the calibration. 298 00:33:57,230 --> 00:34:05,810 But no, for for the most part you're entirely right. It was is it's a team management and common sense role. 299 00:34:06,410 --> 00:34:10,580 So in particular, lots of troubleshooting if if a problem arises in a subsystem. 300 00:34:12,890 --> 00:34:18,980 We had lots of issues with lots of issues with the electronics, the batteries, sensors, the things like this. 301 00:34:18,980 --> 00:34:24,860 And so an important part of it is can we redesign around that problem? 302 00:34:24,920 --> 00:34:33,260 Can we tweak the design such that that problem goes away and which more often than not is common sense as opposed to specialist knowledge? 303 00:34:33,860 --> 00:34:45,950 And yeah, so, so off we went to Hull and at this point we were given letters by the engineering department and letters that very importantly stated, 304 00:34:46,730 --> 00:34:52,160 you know, to whom it may concern this person is engaged in a mission of national importance. 305 00:34:53,060 --> 00:35:02,719 You must let them pass, because we we didn't know if we'd meet police roadblocks and all of this we never did once made a police roadblock. 306 00:35:02,720 --> 00:35:07,190 Never once did I have to use my my important letter or the whole of code, which is a shame. 307 00:35:07,970 --> 00:35:14,360 And and the other people who came up that that initial. 308 00:35:15,710 --> 00:35:19,760 Trip to Tahoe were key people and. 309 00:35:21,030 --> 00:35:31,030 So she could. There was a project manager who might have to look her name up in a minute. 310 00:35:31,550 --> 00:35:38,860 Actually, she was very important. She was one of Andrew family's trainee medics. 311 00:35:40,300 --> 00:35:51,820 And I had previously had a career in the RAF working as an engineer and looking after helicopters and had made a change not late in life by any means. 312 00:35:51,820 --> 00:35:59,980 She's only three or four years older than me, I think. But certainly she'd made a change too, to become a graduate doctor. 313 00:36:00,670 --> 00:36:09,520 And so at this stage she was going through the first years of her medical training and Andrew Farmer, who was one of our tutors and. 314 00:36:12,160 --> 00:36:15,560 So Tyler Edwards was the name I was looking for. 315 00:36:17,290 --> 00:36:21,670 And yeah, she came on as an as project manager. 316 00:36:22,180 --> 00:36:28,890 That was one of the few roles that we did properly defined, and that was a role. 317 00:36:28,900 --> 00:36:35,530 She was magnificent and she was an excellent, excellent manager. 318 00:36:36,190 --> 00:36:47,230 And her RAAF experience proved to be very handy because two times did we then draw on her RAAF contacts in the future. 319 00:36:48,220 --> 00:36:52,270 So one of them was to activate this thing called the Civilian Air Corps. 320 00:36:53,470 --> 00:37:03,310 Which is a network of volunteers who I presume live in way of the day that they will be called up, 321 00:37:03,310 --> 00:37:08,320 is the kind of Thunderbirds situation that they've probably been waiting for their whole lives. 322 00:37:09,040 --> 00:37:16,329 And The Cove, it was one of those times when you could activate the civilian echo and they yeah, 323 00:37:16,330 --> 00:37:23,799 they are volunteers who will undertake missions at times of great need in the national interest. 324 00:37:23,800 --> 00:37:33,070 And so one of the times we activated the civilian echo was to fetch Paul Gula, who is a professor in engineering at Oxford. 325 00:37:34,150 --> 00:37:40,720 And we needed him up in Hull very, very short notice to to trouble fix some software issues we were having. 326 00:37:41,680 --> 00:37:54,790 And so and I believe from the time that we decided we needed him in the hull to a taxi being sent for him to his house, only an hour elapsed. 327 00:37:54,790 --> 00:37:57,640 You know, he got a phone call, pack a bag, a taxi. He's coming to get you. 328 00:37:58,090 --> 00:38:02,710 He's driven to a field somewhere outside Oxford where there's a little propeller plane waiting for him. 329 00:38:03,520 --> 00:38:08,499 And then about an hour and a half later, and he's told to pack light as well, because there's not much space in the cabin. 330 00:38:08,500 --> 00:38:10,990 And if it's too heavy, the plane won't take off. 331 00:38:11,830 --> 00:38:19,450 And then an hour and a half later, he's in Hull and a volunteer civilian volunteer who had no idea of their name or where they came from, 332 00:38:19,870 --> 00:38:25,960 had just flown him up on his own initiative to Hull and deposited them for us. 333 00:38:26,950 --> 00:38:30,390 So that was that was quite an interesting little vignette. 334 00:38:30,400 --> 00:38:37,420 And the the other time in which her RAAF experience was very handy was obtaining the Queen's helicopter, 335 00:38:37,570 --> 00:38:43,629 which I'm not sure if you'd heard of that either, and a similar situation. 336 00:38:43,630 --> 00:38:55,600 We needed to move some circuit boards that had just been manufactured in Redding and by a by really fascinating British company. 337 00:38:55,840 --> 00:38:59,260 I forget their name at the moment, but quite an innovative, 338 00:38:59,260 --> 00:39:05,950 established company who manufacture printed circuit boards, custom custom interconnects, that sort of thing. 339 00:39:06,580 --> 00:39:13,870 And, and that yeah, we needed these circuit boards to be with us in Hull as soon as possible so we could put them in 340 00:39:13,870 --> 00:39:21,339 some ventilators that would then be sent out for evaluation testing by the healthcare regulator, 341 00:39:21,340 --> 00:39:25,750 the MHRA. Once, once again, time was of the essence. 342 00:39:26,440 --> 00:39:37,030 So through Chantelle's contacts and she managed to obtain permission for the Queen's helicopter to do the job. 343 00:39:37,690 --> 00:39:41,800 And so it was dispatched off to Redding, picked them up and flew them up to Hull. 344 00:39:41,920 --> 00:39:49,600 And we did all downed tools at that point and we all went to to the airfield by the helicopter was coming in and took some pictures. 345 00:39:49,600 --> 00:39:52,690 I think all of the teams, about 50 of us in total, 346 00:39:53,350 --> 00:40:02,230 went for that because that was partly things were no longer in the supercritical stage at that time. 347 00:40:02,890 --> 00:40:05,890 So we just needed to plug the circuit boards in. 348 00:40:05,890 --> 00:40:13,600 But a lot of the other work had been done and partly I think we all needed the morale boost at that moment in time because. 349 00:40:14,650 --> 00:40:23,980 We'd been in the deep, dark tunnel for quite a while, which is something I will now loop back to, to explain. 350 00:40:24,970 --> 00:40:30,520 So. So we arrived in. 351 00:40:30,520 --> 00:40:39,950 How? Initially the eight of us who'd come up from Oxford and let's call them the the core eight. 352 00:40:39,950 --> 00:40:43,760 We were the boots on the ground and the brief. 353 00:40:45,130 --> 00:40:54,080 Was. Well, I guess the brief was never explained as clearly as it could have been to everyone. 354 00:40:54,740 --> 00:41:02,180 My understanding was that the purpose of going up there was to hand over the project. 355 00:41:03,170 --> 00:41:07,040 It was you guys have you you've done a lovely effort. 356 00:41:07,040 --> 00:41:10,880 You've made your prototype design. Thanks very much. 357 00:41:11,180 --> 00:41:14,360 We've teamed you up with some professionals now who know what they're doing. 358 00:41:15,020 --> 00:41:20,900 So go up there, you know, explain it to them, hand it over, and just let them get on with it. 359 00:41:21,140 --> 00:41:24,600 Now they'll do the rest. And. 360 00:41:26,540 --> 00:41:31,520 I'm not sure what Smith and Nephew were expecting of from their side. 361 00:41:31,760 --> 00:41:35,990 And at any rate. It wasn't quite. 362 00:41:37,170 --> 00:41:44,200 But it wasn't quite that neat. Clean separation as this is now your project. 363 00:41:44,220 --> 00:41:49,140 I hand it over to you. Thanks very much. Good luck. It didn't quite work out like that. 364 00:41:49,740 --> 00:41:50,250 And. 365 00:41:51,420 --> 00:42:02,100 So we and the reason why that's important is because we initially went up thinking we'd be there for two or three days and so had to act accordingly. 366 00:42:03,060 --> 00:42:07,049 I remember I live quite close to the IBM at the time, 367 00:42:07,050 --> 00:42:16,200 so I remember sprinting home and picking up two sets of underwear in a shot and not set thinking we'd only be there for a few days. 368 00:42:17,070 --> 00:42:26,820 Of course, predictably we ended up staying for three and a half weeks, during which time I was still on massive underwear and t shirts and that's it. 369 00:42:29,290 --> 00:42:32,690 And. Yeah, well, what happened? 370 00:42:33,170 --> 00:42:40,940 The way things did play out was it was a handover, but it remained a much more collaborative effort. 371 00:42:41,360 --> 00:42:54,460 And in particular. The the system needed major redesigns in pretty much every respect before it could be manufactured at scale. 372 00:42:55,390 --> 00:43:05,610 However. Smith and nephew on their own would not have been able to achieve those redesigns in a quick enough timeframe. 373 00:43:05,850 --> 00:43:12,270 Let's say so in particular, the thing that Smith and Nephew excelled at was designed for manufacture. 374 00:43:12,840 --> 00:43:23,250 So that is, how can we redesign the device such that it becomes extremely easy to manufacture? 375 00:43:23,610 --> 00:43:30,090 So one specific example of this was the case of the device, the physical enclosure. 376 00:43:30,720 --> 00:43:35,129 And they very quickly through through what we'd done out the window, 377 00:43:35,130 --> 00:43:44,730 and they went for a single sheets of thin steel that is cut with a laser and the template is scored into it using a laser, 378 00:43:44,970 --> 00:43:48,210 and then it's robotically folded into a box. 379 00:43:49,110 --> 00:43:58,350 And and so just like that, that single step, you've dramatically simplified the assembly of the whole thing and it can all be automated. 380 00:43:59,160 --> 00:44:02,280 And that's it's a far superior solution. 381 00:44:02,520 --> 00:44:08,040 And so that kind of knowledge was, you know, was invaluable. 382 00:44:08,040 --> 00:44:15,540 And we would never have made those same decisions because we don't manufacture anything university engineering departments. 383 00:44:15,550 --> 00:44:19,860 We sit around having ideas. We don't actually ever have to build anything ourselves. 384 00:44:20,400 --> 00:44:30,870 With the exception of gym in the workshop. So so a lot of that design effort went into addressing those kinds of questions. 385 00:44:31,260 --> 00:44:34,409 And that's something I was involved in a bit as well. 386 00:44:34,410 --> 00:44:46,430 I remember we had. Quite a fun session in all of that boardrooms and where they had the heads of the manufacturing teams were all there. 387 00:44:47,450 --> 00:44:50,870 Four or five people, very senior in manufacturing were there. 388 00:44:51,590 --> 00:44:55,040 And then it was just me and one other from the Oxfam team. 389 00:44:55,730 --> 00:45:03,260 And we we were basically taking apart the prototype device we had and then reassembling it in different orders. 390 00:45:03,410 --> 00:45:11,690 So we kept taking apart and then trying to assembler in this order, in that order and, and time it how long it took each, each different route. 391 00:45:12,110 --> 00:45:21,380 And that's the kind of basic hands on work that they do to work out what is the optimal route to, to assemble it. 392 00:45:21,680 --> 00:45:26,330 And the reason that they were putting so much effort into this is because they'd already cleared out one of their 393 00:45:26,570 --> 00:45:35,750 warehouses on the site and they'd started putting together a manufacturing line for it with I believe they're about. 394 00:45:37,180 --> 00:45:40,900 That stations 30 or 40 stations on this manufacturing line. 395 00:45:41,290 --> 00:45:46,000 They already had a team of volunteers who were going to work the line. 396 00:45:46,780 --> 00:45:51,040 And so they were really pouring money and resources into this. 397 00:45:51,070 --> 00:45:55,450 In total, they spent in excess of £6 million, I think, on the project. 398 00:45:56,290 --> 00:46:00,849 Yeah. And they were really getting ready to to manufacture at scale because because 399 00:46:00,850 --> 00:46:06,340 that was what we were led to believe was going to happen by the government. 400 00:46:09,550 --> 00:46:21,160 But then for the other parts of the. Other aspects of the project in Oxford, it turns out, needed to remain much more involved, 401 00:46:21,580 --> 00:46:27,190 and in particular, the thing that caused by far and away the most headaches was the control software. 402 00:46:28,300 --> 00:46:32,470 So there's there's two types of software on the device. 403 00:46:33,160 --> 00:46:43,450 There's a basic interface, which is to say there's a small screen that has buttons on it and there are menus and you 404 00:46:43,450 --> 00:46:47,980 can scroll through the menus and you can change the settings and you do all of this. 405 00:46:49,240 --> 00:46:58,060 And it also measures in reports key metrics about the patient so that oxygen saturation and things like this. 406 00:46:59,200 --> 00:47:04,300 So that's one subset of the system of the system's software. 407 00:47:05,430 --> 00:47:10,560 And then the other subset of the system software is the the control software. 408 00:47:10,920 --> 00:47:21,180 So if the user has requested deliver 400 millilitres at 12 breaths per minute to this patient and do not exceed 25 centimetres of water pressure, 409 00:47:22,200 --> 00:47:27,710 what software actually. Takes responsibility for ensuring that happens. 410 00:47:27,730 --> 00:47:34,510 That's the control software. And unfortunately, it turns out the Smith and Nephew, 411 00:47:35,200 --> 00:47:43,089 I think this was a learning experience for them that surprised that in-house software team, unfortunately, 412 00:47:43,090 --> 00:47:53,470 just did not have the capability to address these problems at speed, and that particularly important in the context of a medical device because. 413 00:47:54,750 --> 00:47:58,970 You know, universities these days, a lot of what we produce is we we churn out software. 414 00:47:59,600 --> 00:48:05,060 A lot of my degree was churning out software algorithms that are now used in other universities, 415 00:48:05,750 --> 00:48:09,890 but they are far from perfect and they have bugs in them. They have bugs that I don't know about. 416 00:48:10,640 --> 00:48:20,030 And when a bug arises, someone can email me and hopefully they bring my attention to it and then I can fix it. 417 00:48:20,360 --> 00:48:24,290 But the bugs are never safety critical because the software I have written is never 418 00:48:24,290 --> 00:48:28,790 being used in a life or death situation to make a decision on someone's treatment. 419 00:48:30,570 --> 00:48:38,490 A the software that goes into a ventilator when someone's in acute respiratory distress is 100% safety critical. 420 00:48:39,090 --> 00:48:49,380 And therefore, there are extremely strict rules about how you can write software that goes on to such a device and how you have to test the software. 421 00:48:50,280 --> 00:48:55,860 And they make and they make the process very slow and difficult. 422 00:48:57,180 --> 00:49:02,730 It's a laborious process to write software in the correct manner in that kind of application. 423 00:49:05,040 --> 00:49:10,260 And so that this is where that was a very unfortunate skills gap. 424 00:49:10,380 --> 00:49:19,710 One would have assumed the Smith and Nephew in-house software team had the necessary skills, and they'd be able to do that quickly at speed. 425 00:49:20,580 --> 00:49:26,670 And unfortunately, Smith and nephews in our software capability was just not very strong at all. 426 00:49:28,400 --> 00:49:33,020 Largely, I think, because their existing product lines do not make heavy use of software. 427 00:49:33,030 --> 00:49:35,630 It's just not something they've had to do very much previously. 428 00:49:36,990 --> 00:49:50,930 And we Oxford people, we have a lot of capability in writing software, but we never have to do it in such a constrained safety critical manner. 429 00:49:51,980 --> 00:50:01,670 And so this was by far and away the biggest problem we faced in that second phase of the project when we were preparing to manufacture is with Nephew. 430 00:50:01,680 --> 00:50:07,340 We have continual issues with getting the software to work, verifying it was safe. 431 00:50:08,380 --> 00:50:14,140 And being in regulatory compliance. And that's why we had to to fly up. 432 00:50:14,860 --> 00:50:20,710 Paul Gula from Oxford, a very short notice. He was leading the control side of things. 433 00:50:21,460 --> 00:50:27,640 And also special mention should go at this point to Michael Garcia, who is another Ph.D. student. 434 00:50:29,080 --> 00:50:34,300 He was he's in Paul's group or was in Paul's group at the time, also at Trinity. 435 00:50:35,190 --> 00:50:44,170 And he he was the the magician of get it's called get is a software tool. 436 00:50:44,740 --> 00:50:49,180 And that in this context allows people to collaborate. 437 00:50:49,510 --> 00:50:56,770 So get is a mechanism by which you can have ten people working on different aspects of the same project. 438 00:50:57,420 --> 00:51:00,540 But I think it's GitHub. I've heard of GitHub. Exactly. 439 00:51:00,550 --> 00:51:05,580 Yeah. Yeah. And it allows yeah, 440 00:51:05,590 --> 00:51:10,329 you can have ten people working on ten different sections of the same project and get 441 00:51:10,330 --> 00:51:16,600 is the mechanism that synchronises it all back together creates a centralised copy. 442 00:51:17,020 --> 00:51:26,320 It's a fabulously powerful tool but is quite difficult to use, particularly the advanced features. 443 00:51:27,100 --> 00:51:30,520 And Michael Garcia was a magician at this. 444 00:51:30,550 --> 00:51:35,170 He he was coordinating everything from his kitchen table. 445 00:51:35,200 --> 00:51:38,830 He never did come up to actually, he he was always remote, 446 00:51:39,730 --> 00:51:45,820 but I only learned relatively late in the project he was the guy taking responsibility for that. 447 00:51:47,060 --> 00:51:51,760 And in fact, in so doing, he inspired me after this to go out and don't get properly. 448 00:51:51,790 --> 00:51:56,380 Because at that point, I'd only ever done in a very superficial manner by now. 449 00:51:56,680 --> 00:52:05,170 And a bit better at that. But that's purely through having seen first hand what it's capable of in the hands of someone competent by Michael Gaskin. 450 00:52:06,760 --> 00:52:16,260 So, yeah, I think. That surmises the the further development work we had to do and how. 451 00:52:17,300 --> 00:52:21,080 And then the next the next phase. 452 00:52:21,470 --> 00:52:26,260 And also just to say it was really fun working with the team at Smith and Nephew. 453 00:52:27,950 --> 00:52:31,630 They. They were all volunteers. 454 00:52:31,650 --> 00:52:36,840 They didn't have to do it. And. It's not staff members, but volunteers. 455 00:52:37,180 --> 00:52:40,020 Yeah. Yeah. They were all stuff of Smith nephew, but. 456 00:52:41,990 --> 00:52:49,129 But all of you know, all the Smith nephew stuff had been sent home at this point, all the non-critical stuff. 457 00:52:49,130 --> 00:52:52,220 And so this was a group of people that had self-selected. 458 00:52:52,940 --> 00:52:57,410 We want to keep coming in to work on this. 459 00:52:58,250 --> 00:53:03,500 And there were there were lots of COVID controls on site, understandably so. 460 00:53:03,500 --> 00:53:12,390 In particular, they they split up their team into two halves and kept them completely isolated from each others. 461 00:53:12,420 --> 00:53:22,070 There was a design team and a manufacture team, and we only ever met the design team in person so we could interact physically with the design team, 462 00:53:22,970 --> 00:53:27,650 but we'd never met the manufacture team physically for COVID safety, of course, 463 00:53:27,650 --> 00:53:32,480 because we were worried that if COVID spread into that group, then they'd never be able to manufacture. 464 00:53:32,990 --> 00:53:36,770 So. So even though we're all on the same side, we were in buildings next to each other. 465 00:53:36,770 --> 00:53:45,740 We had to we had to video conference the whole time to the people next door, which which is a real pain when you're trying to. 466 00:53:46,780 --> 00:53:51,960 Yeah. If you're trying to troubleshoot a problem, particularly a problem that has such a physical, tangible form. 467 00:53:52,770 --> 00:53:53,579 For example, 468 00:53:53,580 --> 00:54:01,710 there's not enough space in the box to put the battery here and then the circuit board is going to hit it at this kind of really basic issue. 469 00:54:03,600 --> 00:54:07,830 Yeah, it's such a pain to have to be doing that over online the whole time. 470 00:54:08,940 --> 00:54:17,040 It's just not how people are meant to work. And where were you living during this period while you were in the. 471 00:54:18,500 --> 00:54:22,790 I think as a Holiday Inn Travelodge. Holiday Inn. Okay. So, yeah, a budget hotel? 472 00:54:23,180 --> 00:54:29,130 Yeah, budget hotel. It's right next door. We had a fleet of minis. 473 00:54:29,140 --> 00:54:36,410 I remember Mini Oxford gave us a load of minis too to run around in because I didn't have a car. 474 00:54:36,430 --> 00:54:40,830 Only a handful of people on the project had a car, so that was nice. 475 00:54:40,840 --> 00:54:45,550 Then we brought these minis out from Oxford. We were driving between the hotel and the. 476 00:54:46,780 --> 00:54:50,110 And like the Italian job. Yeah, pretty much. 477 00:54:50,770 --> 00:54:57,240 But I don't know why we would trade between those inside, because they're basically next door to each other as a five minute walk. 478 00:54:57,860 --> 00:55:07,540 And then towards the end, I started. I started walking anyway, because I needed time out, because I've used the phrase long, dark tunnel. 479 00:55:07,540 --> 00:55:16,300 I'm just waiting for it to get back to you. So to go to it. So, I mean, at this point, we're we're fairly in the tunnel because. 480 00:55:18,330 --> 00:55:24,220 It was really punishing at that. The days were really, really long. 481 00:55:25,210 --> 00:55:32,530 And we were regularly starting at seven or eight in the morning and regularly going past midnight. 482 00:55:33,070 --> 00:55:36,970 And then as things reached the crunch time. Yeah. 483 00:55:37,900 --> 00:55:44,330 The thing that I think really ramped up the pressure was when Boris Johnson went into 484 00:55:44,350 --> 00:55:49,240 hospital and he went into Guys and Thomas's and he was in the intensive care ward. 485 00:55:50,050 --> 00:55:58,450 And it so happened that because we had kings, people involved in the project and we, 486 00:55:58,450 --> 00:56:07,210 we had inside knowledge from the, the ward guys and Thomas's of what his status was. 487 00:56:08,080 --> 00:56:12,940 And it is my understanding that the news reports at the time, quite understandably, 488 00:56:13,090 --> 00:56:19,760 were airing on the more catastrophic side of things compared to what his situation actually was. 489 00:56:19,780 --> 00:56:30,280 It is my understanding, based purely on what I heard Second-hand from clinicians in the team, that he would probably be okay. 490 00:56:32,170 --> 00:56:36,790 Nevertheless, it was at that moment that. 491 00:56:38,290 --> 00:56:46,930 The yeah, the magnitude of things really started to sink in because the isolation was really kicking in at this point. 492 00:56:48,070 --> 00:56:53,190 We'd been up there about a week and a half. You're working in a very small team of people. 493 00:56:53,210 --> 00:56:56,830 You're not seeing the outside world. Your horizon has shrunk enormously. 494 00:56:58,720 --> 00:57:05,950 Also, I happened to be reading a book at the time. That is an excellent book, but it was quite bad timing. 495 00:57:06,730 --> 00:57:10,030 It's a sci fi book about the world ending in slow motion. 496 00:57:11,050 --> 00:57:20,230 It's called 7/8 by Neal Stephenson. But I got to the bit where the world starts to end, just as COVID was really kicking off. 497 00:57:21,130 --> 00:57:29,870 So I'm hoping it's out there reading this book before going to sleep, which probably wasn't helping my spirits enormously. 498 00:57:31,330 --> 00:57:36,639 But when Boris Johnson went into hospital, really started to, you know, thinking, wow, 499 00:57:36,640 --> 00:57:44,290 this could be much bigger than than we initially thought, because up to that point. 500 00:57:45,310 --> 00:57:51,010 Probably naively, given that I was in a slightly privileged position with the information, I had access to. 501 00:57:51,190 --> 00:58:02,050 The fundamental message that the government was still putting out was this will pass, will have quite a few difficult weeks. 502 00:58:02,560 --> 00:58:08,260 Lots of people will go to hospital, but it will pass and in a few months time we'll be out of this. 503 00:58:08,260 --> 00:58:12,400 And there's nothing, you know, nothing catastrophic is going to happen. 504 00:58:12,850 --> 00:58:19,210 And it's at that point when the magnitude of things really started landing for me, that it could be quite catastrophic. 505 00:58:19,870 --> 00:58:24,810 And then the thing that. The other important effect it had. 506 00:58:26,000 --> 00:58:34,910 Boris Johnson going into intensive care was at this point the ventilator challenge became complete chaos. 507 00:58:35,660 --> 00:58:39,770 Everything just the wheels came off at a national level. 508 00:58:40,850 --> 00:58:46,370 And I remember one day we we had a call from. 509 00:58:47,800 --> 00:58:50,490 I believe it's Lord Agnew. Phil Agnew. He was cool. 510 00:58:50,980 --> 00:59:00,310 He was the person in the Cabinet Office who, along with Michael Gove, was sort of taking responsibility at Cabinet level for the ventilator challenge. 511 00:59:01,510 --> 00:59:06,160 And in if we were waiting at this point for the go signal, 512 00:59:06,670 --> 00:59:15,610 we'd been told and the government had placed an order for 6000 units minimum, that was an option for 6000 more. 513 00:59:16,060 --> 00:59:21,070 And we'd been told to prepare to manufacture a rate of 5000 a week, I believe. 514 00:59:22,470 --> 00:59:24,900 So. Yeah. We, 515 00:59:25,440 --> 00:59:33,030 we've been told we we're going to need some upfront and we're probably going to need you to maintain a high rates of production for a period of time. 516 00:59:34,290 --> 00:59:40,410 And, and so in response to that, Smith and nephew, you know, started spending a lot of money. 517 00:59:41,710 --> 00:59:47,740 Getting hold of components became a huge challenge, which I'll also come back to in a minute, 518 00:59:47,740 --> 00:59:54,190 because this was one of the most chaotic and poorly thought out aspects of the ventilator challenge. 519 00:59:54,190 --> 00:59:57,940 It was shockingly coordinated. 520 01:00:00,540 --> 01:00:06,570 But when Boris Johnson went into hospital, we we got a phone call and we were candidly told off the record. 521 01:00:07,410 --> 01:00:14,219 While Boris is in intensive care, no one is going to make any decisions whether you should proceed or not. 522 01:00:14,220 --> 01:00:24,080 Proceed. Decision making stopped. Everything stopped and it was Michael Gove or Theo Agnew who told us that. 523 01:00:24,500 --> 01:00:30,650 And. And I think at this point, the politics becomes unavoidable. 524 01:00:31,040 --> 01:00:35,809 Something that was said about Boris Johnson's cabinet from day one way before COVID started, 525 01:00:35,810 --> 01:00:41,060 but something that was said about his cabinet was his cabinet of lightweights who have been put that because, 526 01:00:41,180 --> 01:00:44,390 you know, they're not going to rock the boat. They don't stand up to him. They agree with him. 527 01:00:45,170 --> 01:00:53,390 And yet we very clearly saw as soon as the man at the top was out of action, everything just grinds to a halt. 528 01:00:53,420 --> 01:00:56,630 No one was going to make a decision until he was back in action. 529 01:00:57,560 --> 01:01:06,530 And and that for me, and that's when I came to realise there are no adults in the room. 530 01:01:07,610 --> 01:01:14,409 That was the. The main take home of COVID for me, which hit me really hard, actually. 531 01:01:14,410 --> 01:01:20,550 But. Yeah, it was shocking. There's such chaos and there were no adults in the room. 532 01:01:21,660 --> 01:01:29,790 You expect when things get really bad, you expect that someone somewhere is going to take the lead and make it okay. 533 01:01:30,660 --> 01:01:34,050 This is a very childlike belief. It's very, you know, innocent belief. 534 01:01:34,830 --> 01:01:40,410 And it's these moments like that, you come to realise, no, that is not how the UK operates. 535 01:01:40,740 --> 01:01:45,150 I don't know about other countries. Very few countries came through COVID in a good way. 536 01:01:46,880 --> 01:01:51,800 Certainly in the UK there were no adults in the room at this point. It was complete pandemonium. 537 01:01:52,670 --> 01:01:58,930 And then. Because we had been led to believe we needed to manufacture thousands of units. 538 01:01:59,770 --> 01:02:02,170 We started going through our supply chain. 539 01:02:02,920 --> 01:02:12,430 So this was an exercise in contacting everyone who supplied components for the ventilator and and asking them how many parts have you got available, 540 01:02:12,440 --> 01:02:16,300 how quickly can you provide them? And there were a few bottlenecks. 541 01:02:16,780 --> 01:02:22,750 And were they all UK suppliers or was some of them overseas completely global? 542 01:02:23,170 --> 01:02:28,990 So so in some respects we were quite innovative and resourceful. 543 01:02:29,020 --> 01:02:35,170 So for example, our oxygen sensor that we used in us was a scuba diving oxygen sensor. 544 01:02:36,220 --> 01:02:42,940 And I believe that we were the only people to use a scuba diving oxygen sensor. 545 01:02:42,940 --> 01:02:48,190 But that was quite fortuitous for us because I was the one to actually make the call. 546 01:02:48,730 --> 01:02:57,970 And I called the supplier up one morning and told them that will buy your entire stock place and put it on the Smith and Nephew credit card. 547 01:02:58,540 --> 01:03:05,740 And that was half a million pounds of purchase in one go that I was making on behalf of Smith nephew. 548 01:03:06,610 --> 01:03:13,209 And that was that was one of those moments where you it's a lot of responsibility that I'd never previously had before. 549 01:03:13,210 --> 01:03:15,280 And you come to realise that, you know, 550 01:03:15,280 --> 01:03:24,220 Smith and Nephew really taking a huge amount of trust on this because they're letting 20 year old PhDs call up and just spend money on their behalf. 551 01:03:25,310 --> 01:03:31,150 And so that was something where the supply chain was good because no one else was using those devices. 552 01:03:31,930 --> 01:03:46,840 And so therefore we had a free run at it. Great. One of the really horrendous bottlenecks was nest hoses that caused NIST and in any NHS hospital. 553 01:03:48,530 --> 01:03:54,980 There's a when you need to access high flow oxygen or pressurised air, 554 01:03:55,550 --> 01:04:01,340 that is a plug on the wall and it has a special type of sitting on it like a garden hose almost. 555 01:04:01,970 --> 01:04:09,140 And you can just jam your pipe on the air and it will click and then you do whatever you needed to do. 556 01:04:09,440 --> 01:04:16,160 And that fitting is called a nest fitting and it's standardised across all hospitals in the U.K. I don't know if it's used elsewhere. 557 01:04:17,270 --> 01:04:27,250 I'm. And so therefore, for a ventilator, you need a hose to plug into the wall and then plug into the the device itself. 558 01:04:28,030 --> 01:04:31,140 And. By. 559 01:04:32,560 --> 01:04:37,389 But this is one of the lessons that we've learned globally since COVID is around 560 01:04:37,390 --> 01:04:42,969 supply chain concentration and the fact that it turns out in in a few key areas, 561 01:04:42,970 --> 01:04:47,410 the world is hugely dependent on the tiny number of supplies in the UK. 562 01:04:47,440 --> 01:04:51,970 To my knowledge, there's only one supplier of doses. 563 01:04:53,020 --> 01:04:57,790 And that's probably because day to day there is a tiny demand for nest houses. 564 01:04:58,630 --> 01:05:02,720 There's only so many hospitals in the country. They only need so many houses. 565 01:05:02,740 --> 01:05:06,940 Every now and then they probably break and replace them. But that's it. 566 01:05:08,140 --> 01:05:12,220 And what was not planned for is that. 567 01:05:13,150 --> 01:05:16,540 One day something like the ventilator challenge would come along. 568 01:05:17,660 --> 01:05:23,660 And the government would go round to all of British industry and say. 569 01:05:24,660 --> 01:05:28,860 And, you know, what's the maximum number of ventilators you can prepare? 570 01:05:29,940 --> 01:05:36,990 And start buying the components to do so. And they gave the green light to many teams, and I believe. 571 01:05:38,850 --> 01:05:46,380 I believe that the total demand for ventilators in the UK was projected at 50 or 60,000. 572 01:05:46,890 --> 01:05:52,680 That was the number that was required to get through the first wave, give or take. 573 01:05:53,070 --> 01:05:57,860 And how how many are then in normal times in operation in hospitals? 574 01:05:58,230 --> 01:06:05,220 Probably down to ten or 20,000. I believe I am less certain on that particular figure. 575 01:06:05,480 --> 01:06:10,150 And given it's not my not my day to day area of expertise. 576 01:06:12,360 --> 01:06:18,610 There was this. But this fateful phone call that happened between all the teams, 577 01:06:18,640 --> 01:06:24,360 the ventilator challenge with the Cabinet Office, I wasn't on the call, but then I heard about it. 578 01:06:24,780 --> 01:06:31,980 And one by one, and the person hosting the call for the Cabinet Office went round all the different teams and said, 579 01:06:32,700 --> 01:06:41,339 okay, how many ventilators can you produce? And the numbers that were coming back, I mean, for us, I think we we answered between ten and 15,000. 580 01:06:41,340 --> 01:06:51,060 We were one of the bigger numbers. But all the the big companies that come on board, companies like Ford, I believe Ford were doing them at Dagenham. 581 01:06:51,420 --> 01:06:58,440 Airbus had come on board. Dyson was still claiming that they would be able to manufacture lots. 582 01:06:58,440 --> 01:07:01,830 But I'm firmly of the opinion Dyson was only ever a publicity stunt. 583 01:07:02,670 --> 01:07:06,300 I do not believe that was ever a serious effort on that part. 584 01:07:07,140 --> 01:07:18,330 And the problem is that the total number of ventilators that were claimed could be delivered, I believe came back over 200,000. 585 01:07:20,120 --> 01:07:23,210 And so there was now this issue of we. 586 01:07:24,500 --> 01:07:25,730 We've cried wolf. 587 01:07:25,970 --> 01:07:35,600 We've got all of industry to put down their tools and focus on this problem all at the same time with zero coordination between the different groups. 588 01:07:35,990 --> 01:07:44,360 We've put more headlong onto this, and now actually the number that they've come back with is way over what is required. 589 01:07:45,590 --> 01:07:51,980 And yet they still weren't willing to coordinate the supply of resources. 590 01:07:52,790 --> 01:07:58,220 And this comes into this becomes visible. 591 01:07:59,380 --> 01:08:10,680 The morning I called the man who manufactures nest hoses in the UK, of which every single ventilator manufactured by any team would need a nest hose. 592 01:08:10,690 --> 01:08:15,540 That is a party you absolutely cannot design around. And I asked him, How many hoses have you got? 593 01:08:15,550 --> 01:08:19,030 How many can you supply? And he just broke down in tears. 594 01:08:19,450 --> 01:08:22,460 And he said, you're the fourth call I've had this morning. 595 01:08:23,740 --> 01:08:27,200 I've already been asked to provide tens of thousands. 596 01:08:27,220 --> 01:08:31,360 I have a thousand in stock. There are none in coming any time soon. 597 01:08:32,380 --> 01:08:36,610 And you guys keep calling me up and ordering tens of thousands. 598 01:08:37,550 --> 01:08:42,230 And then I said, okay, this is you know, this is a huge issue. 599 01:08:42,260 --> 01:08:46,790 Thank you for telling me. And I tried to find out more about the problem and what I was planning to do. 600 01:08:47,860 --> 01:08:54,100 Was relayed back to the Cabinet Office because we'd been given instructions to go out and check your supply chain. 601 01:08:54,400 --> 01:09:01,870 And if there are any issues, report them back to the Cabinet Office and we will try and coordinate centrally and try and get involved. 602 01:09:02,470 --> 01:09:11,020 And I said this to the guy and I said, I will I will report this back to the Cabinet Office and hopefully they can tidy up. 603 01:09:11,020 --> 01:09:17,470 And he said, The Cabinet Office have already called me and they just screamed at me and told me to, you know, make it happen, find a way. 604 01:09:18,220 --> 01:09:23,200 So there was no I don't know who placed that call from the Cabinet office. 605 01:09:24,400 --> 01:09:33,160 Maybe it was the Cabinet office, maybe it wasn't the Cabinet Office. Maybe it was someone trying to speak with the the authority of the Cabinet Office 606 01:09:33,160 --> 01:09:37,000 because there were dozens of consultants involved in the project at this point, 607 01:09:37,000 --> 01:09:39,940 unsurprisingly. Who knows what value they were adding? 608 01:09:40,180 --> 01:09:46,630 Certainly the consultant that was added to our project by the Cabinet Office was largely useless. 609 01:09:46,930 --> 01:09:52,330 Every morning they would tell us, Let me know whatever problems you have and I'll help you fix them. 610 01:09:52,900 --> 01:09:57,309 And every time a problem was brought to his attention, he'd say, Coralie, I hope you're not one. 611 01:09:57,310 --> 01:10:04,930 I'm afraid. So I don't know if this person who called up the next hose supplier was one of those consultants or not. 612 01:10:04,930 --> 01:10:10,990 But at any rate, the guy was pretty much having a breakdown on the phone. 613 01:10:11,350 --> 01:10:21,110 And all because. All because basically every team at this point genuinely thought they would be called on to deliver thousands of devices. 614 01:10:22,400 --> 01:10:28,900 And so were double and triple booking the same hoses. There was no rationalisation, no coordination. 615 01:10:29,950 --> 01:10:37,940 And then one of the final. Well, the final resourceful things we did in this phase to get hold of parts was. 616 01:10:39,740 --> 01:10:45,350 The central component of our ventilator was a rubber balloon, effectively a glorified rubber balloon. 617 01:10:45,770 --> 01:10:49,910 And when you squeeze that balloon, that's what pumps are into the patient. 618 01:10:50,840 --> 01:10:53,900 And the balloons are manufactured in China. 619 01:10:55,250 --> 01:11:03,350 And at this point, pretty much every country in the world had put down an export restriction on any medical product of any nature. 620 01:11:04,130 --> 01:11:10,010 And so we had. I think it was 50,000 of these. 621 01:11:11,810 --> 01:11:17,480 We managed to successfully buy 50,000 of them, and they were in Shanghai, in China, 622 01:11:18,020 --> 01:11:22,640 but we couldn't get them out of Shanghai because of the export restrictions. 623 01:11:24,380 --> 01:11:29,360 And so for a while, lots of lots of creative things were being looked at. 624 01:11:30,140 --> 01:11:34,850 Someone I can't remember who, but someone even had a relationship to Richard Branson. 625 01:11:35,300 --> 01:11:41,300 And so at one point we spoke to Richard Branson about could he send one of his jets over that to pick it up for us. 626 01:11:42,140 --> 01:11:46,790 And in the end, that didn't come off the way we got them out. 627 01:11:46,940 --> 01:11:51,050 This was Shontell as well. Johnson Edwards was doing a lot of this work. 628 01:11:51,470 --> 01:11:58,610 I believe somehow we persuaded someone on the ground in China to label them as footballs. 629 01:12:00,030 --> 01:12:03,960 And then Smith and Nephew were able to send one of their planes out to pick them up. 630 01:12:04,800 --> 01:12:11,310 We managed to get them out, but it was purely through creative accounting, let's call it. 631 01:12:12,090 --> 01:12:23,490 And so these are the kinds of issues that that were faced in trying to find enough components to to build tens of thousands of devices. 632 01:12:24,150 --> 01:12:28,020 But it was it was complete chaos all over the world. Complete chaos. 633 01:12:31,250 --> 01:12:38,380 So. Yeah. A very unusual way of spending what should have been the final year of your dphil? 634 01:12:39,520 --> 01:12:47,200 And so, yes, you ended up spending, what was it, three and a half weeks in in Holland. 635 01:12:47,200 --> 01:12:53,040 All that happened during that time? Yeah, it was very well, I mean, ultimately cut to the chase. 636 01:12:53,050 --> 01:12:56,350 Ultimately, the 6000 audit were never made. 637 01:12:56,470 --> 01:13:01,180 Is that is that correct? Yeah. So. So what happened is. 638 01:13:02,800 --> 01:13:13,990 Oh, device was sent off for testing in Birmingham and the first batch of tests came back that the devices and now it's fundamentally operable. 639 01:13:14,530 --> 01:13:22,120 The device broadly meets what it's required to do, but it's one or two areas require major improvement. 640 01:13:22,510 --> 01:13:33,760 And could you also add this thing called respiratory controlled ventilation, which basically is a slightly different mode of operation? 641 01:13:35,230 --> 01:13:40,360 Where the ventilator will wait for the patient to start breathing again. 642 01:13:40,360 --> 01:13:44,440 And once it senses the patient has started breathing again, it will then help them along. 643 01:13:45,790 --> 01:13:50,570 So. And all of this. 644 01:13:51,600 --> 01:13:54,830 Came about what struck us as slightly odd. 645 01:13:55,280 --> 01:13:58,490 We weren't surprised that one or two areas were quite improvement. 646 01:13:58,610 --> 01:14:08,350 That was entirely predictable. But the fact that they the requirements had suddenly increased quite substantially to 647 01:14:08,360 --> 01:14:14,330 we would now like it to be as an assisted ventilation where it assists the patient. 648 01:14:15,200 --> 01:14:24,950 That was quite a big step up and had not previously been a requirement in the specification and it all was a little bit sneaky behind the back. 649 01:14:27,940 --> 01:14:36,580 That's the first red flag in hindsight. We then went ballistic for four or five days. 650 01:14:38,830 --> 01:14:44,590 Trying to trying to implement that change, which happily we could do that entirely in software. 651 01:14:44,590 --> 01:14:48,040 It didn't require a physical redesign of the device. 652 01:14:48,460 --> 01:14:51,850 It just required reworking the software quite substantially. 653 01:14:53,110 --> 01:15:02,830 The problem with that, though, is, as I already mentioned, writing software for a medical device at high speed is extremely complicated, 654 01:15:03,490 --> 01:15:09,280 let alone when you have a very, you know, stretched team in place to do it. 655 01:15:10,030 --> 01:15:16,689 I never wrote any software for the device. It's not something that's in my skill set or already a handful of people that 656 01:15:16,690 --> 01:15:22,360 were capable of doing so and they had already been worked to the to the bone. 657 01:15:24,280 --> 01:15:28,909 You at one point I. I can't remember what Paul Goulart did, 658 01:15:28,910 --> 01:15:38,209 but I effectively instructed Paul to leave his computer and go and sleep in the factory because he'd been at 659 01:15:38,210 --> 01:15:44,390 his computer for 22 hours or something non-stop and was visibly trembling and he couldn't type any more. 660 01:15:45,500 --> 01:15:52,970 So I noticed that on your CV you said that you had the title of Chief Morale Officer. 661 01:15:53,210 --> 01:15:57,080 Yeah. That was that official? Or was that just a role you took? 662 01:15:58,190 --> 01:16:03,300 It was. It was what? Someone described me as rich, which, yeah, I'm very proud of that. 663 01:16:03,370 --> 01:16:06,920 So. Yeah. Yeah. 664 01:16:09,670 --> 01:16:13,330 So anyway, we went to a great speed to do all of that. 665 01:16:14,710 --> 01:16:19,330 And this was the point when. Tim Denison described it as a death march. 666 01:16:20,870 --> 01:16:25,910 It was just a death march when you felt you knew the project was going nowhere? 667 01:16:26,450 --> 01:16:33,020 Yeah, because we we were in limbo. We'd been told, you need to be ready for thousands of devices ASAP. 668 01:16:33,260 --> 01:16:36,800 And the order never came in. We never got a go order. 669 01:16:37,400 --> 01:16:41,060 And for the first part, it was what's happening to Boris Johnson. 670 01:16:41,750 --> 01:16:46,310 No one's going to make a decision. So he comes out and then he came out and still no decision was coming. 671 01:16:47,270 --> 01:16:50,780 And so we didn't really know what was happening and. 672 01:16:51,830 --> 01:16:58,130 At this point, I think one or two people that had had to leave Hull and gone back to Oxford. 673 01:16:59,630 --> 01:17:03,110 I just kept breaking down, crying at random moments. 674 01:17:03,860 --> 01:17:09,920 I started walking in and out of the factory between the hotel just because I needed the time out. 675 01:17:09,930 --> 01:17:16,420 But I remember just crying all the time. It was a very intense period and. 676 01:17:17,680 --> 01:17:24,130 And and then we managed to get the device ready to go back for testing. 677 01:17:25,730 --> 01:17:29,750 Second time in Birmingham, and this time they came back. 678 01:17:30,620 --> 01:17:33,770 The test results came back. It met the requirements. 679 01:17:34,280 --> 01:17:39,670 It was a sufficient device. I forget the exact terminology that was used on the report. 680 01:17:39,680 --> 01:17:43,850 I have the report myself. We we all got a copy of the report, but it meets the requirements. 681 01:17:45,520 --> 01:17:50,839 And then we got a letter signed by Michael Gove shortly afterwards saying, you know, 682 01:17:50,840 --> 01:17:55,940 thanks so much for all the effort you put into it, but unfortunately your device is deficient. 683 01:17:56,300 --> 01:18:00,890 It just doesn't meet the requirements and so you can all pack up and go home. 684 01:18:03,140 --> 01:18:11,630 And that was that. And what effectively happened and this is why about that big article I mentioned earlier in the FT about the ventilator challenge. 685 01:18:13,210 --> 01:18:19,120 What happened is the government got everyone really wound uptight about it. 686 01:18:19,750 --> 01:18:24,700 Industry responded in a more forceful way than than was anticipated. 687 01:18:25,890 --> 01:18:33,060 And to put it bluntly, I think the government didn't want the embarrassment of going around shutting people down. 688 01:18:34,350 --> 01:18:40,410 And so they were doing it by the backdoor. By shifting the goalposts, they kept shifting the goalposts. 689 01:18:41,510 --> 01:18:45,680 Such that they could find an excuse to then say, Oh, your device doesn't matter anymore. 690 01:18:46,520 --> 01:18:50,750 And we were naive and stupid and we didn't read between the lines. 691 01:18:51,260 --> 01:18:56,810 The actually, it didn't matter whether we kept meeting the new requirements, 692 01:18:57,500 --> 01:19:02,540 the government would have just kept doing something to dismiss the whole project. 693 01:19:03,590 --> 01:19:07,430 Then there was a brief moment when we. 694 01:19:08,700 --> 01:19:11,219 I think Smith and Nephew were making the case that, look, 695 01:19:11,220 --> 01:19:17,280 we've we've already sunk huge sums of money into this and we've already acquired thousands of parts to build. 696 01:19:17,280 --> 01:19:20,490 Then let us build them and send them to India. 697 01:19:21,450 --> 01:19:24,479 So then there was this phase of the project of looking for alternative markets. 698 01:19:24,480 --> 01:19:28,470 So India was one of them. We looked into Mexico quite a lot. 699 01:19:29,550 --> 01:19:33,959 Interestingly, A, it could have gone to Mexico, 700 01:19:33,960 --> 01:19:43,680 but it would have struggled a little bit more because the the maximum volume that the ventilator can provide is 600 millilitres. 701 01:19:44,940 --> 01:19:50,610 And by the volume of that, you need to provide scales with the body mass of an individual. 702 01:19:51,210 --> 01:19:54,930 So you normally do a millilitres per kilogram of body mass figure. 703 01:19:56,220 --> 01:20:02,370 Interestingly in Mexico that if needed a ventilator up to about 800 and because average weight 704 01:20:02,460 --> 01:20:08,520 is higher in Mexico basically got heavier people so so it wouldn't have been so well suited, 705 01:20:08,520 --> 01:20:16,229 but it could have been perfectly operable for India. And and that's where the the Oxford Foundation comes in. 706 01:20:16,230 --> 01:20:23,310 It's effectively it's and people trying to find some use. 707 01:20:23,640 --> 01:20:32,350 So it's come out of the device. It could you know, it could be relevant for a future epidemic. 708 01:20:32,890 --> 01:20:37,930 Unfortunately, this is not going to be the last respiratory pandemic the world sees. 709 01:20:38,620 --> 01:20:46,360 So so it could be used for that. And also the the other argument that we various people tried to make to the government is. 710 01:20:47,720 --> 01:20:54,290 You could just spend the money now and buy 10,000 of them and stick them in a warehouse for the next time, 711 01:20:55,100 --> 01:20:59,390 because there will be a next time and top 10,000 emergency devices would be quite handy. 712 01:20:59,990 --> 01:21:07,030 To my knowledge. I believe at the time when the whole ventilator challenge disintegrated, 713 01:21:07,090 --> 01:21:10,390 I'm not going to say it was shut down because it was never shut down properly. 714 01:21:10,400 --> 01:21:17,440 It just disintegrated in a completely chaotic, uncontrolled fashion at that moment in time. 715 01:21:17,980 --> 01:21:25,240 I believe Oxford with Smith, the nephew, was the project that had the capacity to manufacture the most ventilators. 716 01:21:25,930 --> 01:21:34,870 It was the cheapest. It was about £1,000 per unit, whereas the cost of a typical ICU ventilator device is about £20,000. 717 01:21:35,590 --> 01:21:43,030 So it's an incredibly cheap device. Smith and Nephew had managed to get the manufacturing time down to 90 seconds per unit. 718 01:21:44,150 --> 01:21:48,260 And it was the only one that could be manufactured at thousands per week. 719 01:21:48,440 --> 01:21:55,890 None of the others could do thousands per week. But according to Michael Gove doesn't meet requirements. 720 01:21:56,370 --> 01:22:00,150 It was a deficient device according to him, 721 01:22:00,540 --> 01:22:07,200 although he doesn't probably know that we we have the report from the regulator ourselves anyway, so we know that's complete nonsense. 722 01:22:07,720 --> 01:22:12,660 Now you go and I mean, with hindsight, I mean, 723 01:22:12,660 --> 01:22:17,219 I think I've heard it said that it actually turned out we didn't need so many ventilators 724 01:22:17,220 --> 01:22:23,160 after all that that once they were redistributed from one hospital to another, 725 01:22:23,730 --> 01:22:29,160 there were more or less enough to go round. I mean, like the Nightingale, all these Nightingale hospitals that were set up. 726 01:22:29,160 --> 01:22:33,690 And in the end they turned out not to be needed. Yeah, no. 727 01:22:34,560 --> 01:22:42,750 Broadly you are absolutely correct. I think, you know, moments in time it would have been useful. 728 01:22:42,750 --> 01:22:47,280 Thompson Some more ventilators. I'm sure there were moments in time when. 729 01:22:48,820 --> 01:22:52,690 Hospitals were uncomfortably tight on ventilators, capacity. 730 01:22:54,040 --> 01:23:00,670 But broadly speaking, you are correct. We did not require tens of thousands of devices in the UK, thank God. 731 01:23:02,380 --> 01:23:06,610 But that was more than anything. It just turned out that way. 732 01:23:06,790 --> 01:23:14,740 With regards to the Nightingales, an interesting little fact about that is because we we designed our device for nightingales. 733 01:23:15,550 --> 01:23:22,600 So during the design process we because we had loads of clinicians on the team, which is a fantastic attribute to have. 734 01:23:23,080 --> 01:23:31,440 We were talking to the recently appointed heads of the Nightingales people setting them up and they were telling us what they wanted from our device. 735 01:23:31,450 --> 01:23:35,859 So for example, a standard ICU ventilator comes on the stand. 736 01:23:35,860 --> 01:23:41,229 It's got wheels, It's it is its own thing. Ours is a box that you can put on the floor. 737 01:23:41,230 --> 01:23:44,980 You can clip it to a bed, you could clip it to another thing. 738 01:23:46,210 --> 01:23:49,630 It's a big steel box so that if you walk into it, it doesn't matter. 739 01:23:50,290 --> 01:23:56,589 A is designed to be left lying around in a completely chaotic environment 740 01:23:56,590 --> 01:24:01,239 because that's what the heads of Nightingales that were calling us up saying, 741 01:24:01,240 --> 01:24:05,380 I want this on, I want bats on it. And we were saying, Yeah, we can do that. 742 01:24:05,960 --> 01:24:13,840 And interestingly with the Nightingales it is highly debateable whether they would, even if they had been required, 743 01:24:14,320 --> 01:24:18,940 it is highly debateable if they would have ever been useful because they would 744 01:24:18,940 --> 01:24:23,860 have been staffed by nurses who were already allocated to other hospitals. 745 01:24:24,010 --> 01:24:27,940 Actually, they just weren't enough people to fill them. Yeah, yeah. 746 01:24:28,780 --> 01:24:29,800 But in the meantime, 747 01:24:30,310 --> 01:24:40,270 you and your colleagues have designed and prototyped and developed the manufacturing process for a device that sounds like a very good device. 748 01:24:40,780 --> 01:24:45,940 And does it does oxidant still exist as an entity and what are its plans for the future? 749 01:24:46,690 --> 01:24:51,520 So oxygen does still exist. It's a social enterprise. 750 01:24:52,720 --> 01:24:57,640 I myself, I'm not involved in it running Oxfam. 751 01:24:57,820 --> 01:25:06,010 I'm not involved in any regard. Actually in Oxfam, it's mainly it's mainly the professors who are involved in that. 752 01:25:06,940 --> 01:25:12,040 And I believe they they envisage going into. 753 01:25:14,530 --> 01:25:18,549 Other markets where ventilator capacity is more constrained. 754 01:25:18,550 --> 01:25:26,380 So broadly speaking, there are many contacts in the developing world where it'd be really handy to have a ventilator. 755 01:25:26,770 --> 01:25:32,739 So not just for respiratory disease, but, for example, in childbirth. 756 01:25:32,740 --> 01:25:35,680 I believe under some circumstances, if there's a complication, 757 01:25:35,680 --> 01:25:42,430 it can be very advantageous to have ventilator available and there's many aspects of the oxygen really nice. 758 01:25:42,820 --> 01:25:51,850 You can run it on a compressor, an industrial air compressor, whereas a conventional hospital ventilator requires a medical grade. 759 01:25:51,850 --> 01:25:58,870 Air supply is called. To put it simply, if you are in many regions of the world, 760 01:25:58,870 --> 01:26:04,509 you're not going to find a medical grade air supply, but a little industrial compressor, no problem at all. 761 01:26:04,510 --> 01:26:08,860 You'll be able to find that. So so that that's the vision for it. 762 01:26:08,860 --> 01:26:13,239 But I don't know if they've made any great strides in that direction. 763 01:26:13,240 --> 01:26:19,490 I believe not at this moment in time. So for you. 764 01:26:21,260 --> 01:26:27,370 All that drama in Hull was over by, what, the end of May? 765 01:26:28,180 --> 01:26:34,040 Yeah. Yeah. And then we. He came back down to Oxford. 766 01:26:34,460 --> 01:26:42,930 My housemates had been. Having a great time that's watched every day. 767 01:26:43,200 --> 01:26:50,640 Basically, they'd got baked part into the vernacular and been watching Lord of the Rings back to back. 768 01:26:51,540 --> 01:26:56,130 And they they'd been having a lovely time because really Sunday it was a beautiful spring. 769 01:26:57,720 --> 01:27:01,640 And it was a very jarring experience. 770 01:27:01,680 --> 01:27:04,770 I. To this day, I've lived through lockdown. 771 01:27:04,770 --> 01:27:08,430 Subsequently, of course, I have no idea what that first lockdown was like. 772 01:27:10,010 --> 01:27:14,089 I hear so much has been written and said about that lockdown. 773 01:27:14,090 --> 01:27:18,350 And people were wondering, Oh my God, the world could be different. The world could forever be different. 774 01:27:18,590 --> 01:27:20,570 What will it be like when the dust settles? 775 01:27:20,600 --> 01:27:31,730 There was a lot of curiosity and hope around that first lockdown, and I did not experience any of that because we were in the tunnel and. 776 01:27:32,770 --> 01:27:39,100 Yeah. And it took a long time to. I didn't work again until. 777 01:27:40,600 --> 01:27:46,680 So August that year. I mean, I was trying to work, but I wasn't really. 778 01:27:47,310 --> 01:27:53,910 What did you have left to do? Well, you just writing up your thesis or did you still have my my final. 779 01:27:54,390 --> 01:27:58,740 That was the start of my third year. So I was still about a year to go. 780 01:27:58,740 --> 01:28:02,160 I finished in the end, I actually finished entirely on time. 781 01:28:02,400 --> 01:28:11,550 And it just so happened that when COVID hit, I was ahead of schedule and then the effects of COVID wiped out that buffer. 782 01:28:12,360 --> 01:28:17,070 So in the end, I finished June of 21 and. 783 01:28:19,180 --> 01:28:23,170 I was very angry for quite a long time. 784 01:28:24,470 --> 01:28:28,310 I still I'm quite angry at various bowlers. It comes and goes. 785 01:28:29,810 --> 01:28:38,330 Yeah, just really, really angry. And I can't quite put my finger on why, but it is an incredibly demoralising experience. 786 01:28:40,340 --> 01:28:46,280 But you were, you were taken advantage of. I mean, all of you were in a very cynical way, it sounds like to me. 787 01:28:46,910 --> 01:28:49,790 Yeah, we were, you know, we were happy to do so. 788 01:28:51,670 --> 01:28:59,800 And when the rest of you I mean, how did you share your feelings with the other seven people in the group who'd been through all the. 789 01:29:01,340 --> 01:29:07,340 Yeah. I can't speak for everyone, but I know some people incredibly hard. 790 01:29:07,870 --> 01:29:11,930 Mm hmm. Yeah, it hit some people incredibly hard. 791 01:29:12,200 --> 01:29:18,170 Definitely. Yeah. Yeah. 792 01:29:18,410 --> 01:29:21,590 And then. And then there was Kofi, project number two. 793 01:29:21,830 --> 01:29:27,110 Yes. Which was a lot more fun and with a with a better outcome and lovely feedback from. 794 01:29:27,960 --> 01:29:39,030 Yeah. So tell me about that. Probably it's a more it's a less rollercoaster story, but it's still you know, 795 01:29:39,030 --> 01:29:44,270 it still unfortunately contains some pretty damning indictments of of the system. 796 01:29:46,250 --> 01:29:59,510 So that one starts again on Twitter. And it's also Rob Starke because he just cannot get enough of Twitter though it's early 2021. 797 01:30:00,700 --> 01:30:04,120 And the vaccination campaign is about to launch. 798 01:30:05,080 --> 01:30:15,750 And. There were the nine priority groups that had been identified by the Joint Committee on Vaccination and Immunisation. 799 01:30:16,910 --> 01:30:23,330 And I believe priority group number three or four was housebound individuals. 800 01:30:24,620 --> 01:30:27,680 And so they would not be able to come to a vaccination centre. 801 01:30:28,610 --> 01:30:34,010 The GP or nurse would need to go to the person's house and vaccinate them on site. 802 01:30:35,900 --> 01:30:45,530 And. The the original target was that those top four priority groups, the high vulnerability people, 803 01:30:46,910 --> 01:30:52,020 they had to be done within six weeks of the vaccination campaign starting. 804 01:30:52,040 --> 01:30:55,160 That was the first objective. We need all of them done in six weeks. 805 01:30:56,710 --> 01:31:01,690 And in order to incentivise GP's. 806 01:31:03,550 --> 01:31:08,770 But I should say also that unlike the majority of the vaccination campaign where. 807 01:31:10,110 --> 01:31:15,060 Individuals who could do so would go to a central vaccination site. 808 01:31:15,620 --> 01:31:21,240 You know, one of the big massive vaccination centres and they were organised centrally. 809 01:31:22,570 --> 01:31:29,530 And so. The NHS is all about layers of responsibility and who's looking after which patient. 810 01:31:30,100 --> 01:31:37,960 And so for a lot of people they could go to a central vaccination site and so the authority lies with some central body within the NHS. 811 01:31:39,520 --> 01:31:49,720 Housebound patients were only the responsibility of their local GP and there was no other way that they were going to be vaccinated. 812 01:31:50,260 --> 01:31:57,070 It was purely the responsibility of the GP surgery to make sure that housebound patients were taking care of. 813 01:31:59,270 --> 01:32:04,900 And. And that burden falls extremely asymmetrically. 814 01:32:05,020 --> 01:32:11,890 So if you look at the number of patients that are assigned, talking about all patients here, 815 01:32:12,850 --> 01:32:20,980 the number of patients assigned to each GP surgery in the country, I believe the figures range from about 1500. 816 01:32:21,940 --> 01:32:25,330 In some regions to over 3000. In other regions. 817 01:32:25,750 --> 01:32:31,660 So the density of patient to GP can vary by 100%. 818 01:32:33,830 --> 01:32:41,150 And so you can imagine when it comes to that and treating housebound patients, some regions of the country, in particular the South-West, 819 01:32:41,570 --> 01:32:51,140 Devon, Cornwall, the entire South-West region will have a much higher density of older patients who are frail and likely to be housebound. 820 01:32:52,010 --> 01:32:57,480 And so and who probably also live further apart from the very rural area. 821 01:32:57,890 --> 01:33:04,040 So there's this burden of you need to go and look after these patients is incredibly asymmetric. 822 01:33:04,760 --> 01:33:10,000 And also, astonishingly, no one has any idea how many there are. 823 01:33:11,880 --> 01:33:16,560 No one keeps the numbers I've made for Freedom of Information requests at this point. 824 01:33:16,710 --> 01:33:21,960 Two different authorities within the U.K. for the total number of housebound patients. 825 01:33:23,370 --> 01:33:32,280 The only figure I've been given that has any let's say credibility is a lower bound of 250,000. 826 01:33:33,150 --> 01:33:38,150 I'm led to believe the number is probably about 500, but no less than 250. 827 01:33:39,270 --> 01:33:42,380 But shockingly, no one actually has a number for it. 828 01:33:42,390 --> 01:33:43,620 No one's keeping track of that. 829 01:33:45,330 --> 01:33:53,670 And we've been told by someone at the Royal College of GPS that this this illustrates how the problem even exists in the first place, 830 01:33:54,270 --> 01:33:58,040 because no one has responsibility for them in the central NHS. 831 01:33:58,050 --> 01:34:01,320 And therefore, why would you count them? They're not my problem. 832 01:34:02,340 --> 01:34:06,900 These are patients that consistently fall through the cracks of the system 833 01:34:06,960 --> 01:34:13,590 because no one is charged with looking after them for essential points of view. 834 01:34:14,430 --> 01:34:23,700 So. In order to incentivise GP's to get through vaccinating these people as quick as possible. 835 01:34:24,150 --> 01:34:29,100 And they started putting incentives down. So there was a £10 uplift it was called. 836 01:34:29,730 --> 01:34:38,520 So for every housebound patient a GP vaccinated, they would get an extra £10 on top of the existing right as an incentive for doing so. 837 01:34:39,720 --> 01:34:45,480 The missing link was that there was no technology in place to do so. 838 01:34:47,250 --> 01:34:52,650 You can throw money at the problem. You can tell people I'll pay you twice as much money to do it, 839 01:34:53,280 --> 01:34:58,620 but unless you really give them the means to do so, that's not actually going to make the problem go away. 840 01:34:59,830 --> 01:35:05,889 And this is what Rob became aware of on Twitter in particular. 841 01:35:05,890 --> 01:35:12,130 There was one GP in Wales outside Merthyr Tydfil, who was. 842 01:35:13,330 --> 01:35:18,400 He was tweeting about the challenges he faced and he managed to find a plug in 843 01:35:19,090 --> 01:35:24,910 for Google Sheets whereby if he entered a list of postcodes into Google sheets, 844 01:35:25,510 --> 01:35:30,610 it would automatically locate all of them on a map on Google Maps. 845 01:35:31,210 --> 01:35:36,160 And then he could draw a line between the postcodes and he could make a route. 846 01:35:36,550 --> 01:35:40,780 And then he knew, okay, to do these ten patients, this is the route I'll follow. 847 01:35:41,380 --> 01:35:46,840 And he was very pleased with what he'd done and that he was tweeting about it so that he could share it with other GP's. 848 01:35:47,410 --> 01:35:56,860 And it was a very labour intensive solution, but it was a very crude solution to the problem of how do you efficiently do this? 849 01:35:57,580 --> 01:36:02,830 And so Rob brought this to me and said, surely we could automate this, surely we could do better. 850 01:36:03,760 --> 01:36:09,040 It's a travelling salesman problem. Yeah, is exactly that. 851 01:36:09,370 --> 01:36:19,899 Yeah. And, and because it's the travelling salesman problem solutions that exist, this is a trivial problem to solve. 852 01:36:19,900 --> 01:36:24,920 Now there are many solutions out there. And so, so. 853 01:36:25,180 --> 01:36:28,720 So I got on with that and 48 hours later. 854 01:36:30,020 --> 01:36:36,560 I worked two days and two days, and then we put the basic version online. 855 01:36:38,010 --> 01:36:43,710 And yeah, if it went, it gained a lot of use very quickly. 856 01:36:44,610 --> 01:36:52,800 People started sharing it, word of mouth. So on Twitter and there's loads of WhatsApp groups for GPS. 857 01:36:53,130 --> 01:36:58,890 So in particular someone would come across it and then they would put it on a WhatsApp group and they would share it on. 858 01:36:59,820 --> 01:37:05,190 We kept the site free to use. So at no point have we charged for it and. 859 01:37:06,800 --> 01:37:15,410 Partly because we. Partly because we didn't want to and partly cause it to set up a whole payments processing system, which is really complicated. 860 01:37:15,770 --> 01:37:21,860 It's not the kind of thing you want to do at high speed, as much more interested in just solving the problem than getting it out there. 861 01:37:23,170 --> 01:37:28,750 But that was in my rush to do so. That was one thing that would sting in the tail a little bit further on. 862 01:37:29,590 --> 01:37:41,390 And so within. I think within two or three weeks we'd hit 100,000 patients had gone through the site. 863 01:37:41,750 --> 01:37:47,090 You know, at one point about 10,000 patients a day were running through the service. 864 01:37:48,380 --> 01:37:53,600 So how do you focus? Because people would upload their patients to the site so you could go out? 865 01:37:54,650 --> 01:38:02,510 Yes. So the doctors. The patients, Yeah. The doctors would export an Excel spreadsheet and then you upload the Excel spreadsheet. 866 01:38:02,510 --> 01:38:09,080 And so we can we can count. And all it was doing, it was an elaborate frontend to. 867 01:38:10,220 --> 01:38:15,080 To Google Maps. Basically, I would take the patients. 868 01:38:16,300 --> 01:38:20,460 And and the addresses and I would sort them into smaller groups. 869 01:38:20,470 --> 01:38:23,080 So some of ized. Obviously you didn't have the names. 870 01:38:23,800 --> 01:38:30,580 Yeah, no names and also postcodes, because postcodes are anonymized, you can't identify an individual from a postcode. 871 01:38:30,580 --> 01:38:38,650 It's too broad. But these kinds of data questions just capturing that, unfortunately not in a constructive way. 872 01:38:41,800 --> 01:38:47,500 And so say you upload 50 patients, you're not going to go off and vaccinate 50 at once. 873 01:38:47,500 --> 01:38:51,150 You split them into five groups of ten, for example. So that's what the service does. 874 01:38:51,160 --> 01:38:58,180 You can choose the group size, it splits them off into these clusters and then for each cluster, it goes off to Google Maps, 875 01:38:58,180 --> 01:39:04,150 it gets Google Maps to do the travelling salesman for you, and then it sends the result back to the user. 876 01:39:05,220 --> 01:39:08,760 This is incredibly simple and that's how it was able to be built so quickly. 877 01:39:09,750 --> 01:39:12,870 Nothing in there is novel or unique. 878 01:39:13,440 --> 01:39:21,510 It's just gluing together existing pieces of code already out there and it's going to give it its name. 879 01:39:22,080 --> 01:39:27,030 So you've got it's got a name fancy map facts about. 880 01:39:29,050 --> 01:39:32,490 Yeah. My name, actually. I thought I was quite loud and. 881 01:39:34,050 --> 01:39:41,160 And then, yeah, we had 100,000 patients really quickly. The problem with this is it was all running on my credit card. 882 01:39:42,620 --> 01:39:51,980 So the server costs you highly you pay to to have a server, but that's not actually that expensive. 883 01:39:52,340 --> 01:39:59,149 It's about $7 a month. That's fine. The thing that racks up is API costs code and that's that's a fee. 884 01:39:59,150 --> 01:40:02,420 You pay Google for every address that you look up and you route. 885 01:40:03,350 --> 01:40:06,590 So you as an individual, when you go on Google Maps, they don't charge you. 886 01:40:06,980 --> 01:40:13,460 But if you're starting to do large scale stuff programmatically, they start charging you for that. 887 01:40:14,120 --> 01:40:19,400 And I believe I worked out the final figure at some point was about. 888 01:40:20,390 --> 01:40:24,410 Is it? A couple of pennies per patient was the total cost we were paying. 889 01:40:24,740 --> 01:40:29,210 But then when you consider that for some reasons, I'm not entirely sure. 890 01:40:29,780 --> 01:40:31,939 There's really interesting usage patterns around it. 891 01:40:31,940 --> 01:40:38,900 What people tend to do with Vaccine App is they tend to upload their patients and then they'll generate some routes. 892 01:40:39,200 --> 01:40:44,960 They'll look at them, decide whether they like them or not, and then they'll change some settings and then they'll regenerate. 893 01:40:45,170 --> 01:40:48,620 So they'll actually they'll run the same request we call it. 894 01:40:48,920 --> 01:40:55,490 They'll run that four or five times before they're happy, and then they'll they'll save the final one and use that. 895 01:40:56,570 --> 01:41:00,800 But it means that you've paid four or five times to generate the salaries. 896 01:41:01,280 --> 01:41:09,380 And so long story short, very, very quickly, my credit card was £2,000 down in debt and. 897 01:41:10,940 --> 01:41:15,890 And so the logical thing at this point is you think, well, you'd go to the NHS and say, 898 01:41:16,700 --> 01:41:20,390 would you mind awfully just giving us a bit of money to cover this? 899 01:41:21,020 --> 01:41:25,940 And they say, absolutely not. And they don't want to know. 900 01:41:26,540 --> 01:41:33,100 And this. Just became a Kafkaesque mystery. 901 01:41:33,610 --> 01:41:41,019 We were calling around anyone and everyone trying to persuade them to get involved. 902 01:41:41,020 --> 01:41:46,460 So happily Modelling College said they would pay at least £2,000. 903 01:41:46,480 --> 01:41:49,600 Ideally, could we find someone else as well to match them? 904 01:41:51,220 --> 01:41:56,260 We spoke to Oxford University Innovation. The spin out of the uni. 905 01:41:56,260 --> 01:42:05,710 They they loved it and they were happy to put in, I think up to 15, but that the problem with Oxford funding is it's mainly benefits in-kind. 906 01:42:06,400 --> 01:42:14,020 So it's money towards lawyers fees and things like that. They don't really want to just give you a lump sum of cash and also. 907 01:42:15,840 --> 01:42:19,469 The project and you could call it a spin out, 908 01:42:19,470 --> 01:42:26,130 but it wasn't really a spin out in any meaningful sense of the word because we weren't really planning to monetise it in any sense. 909 01:42:26,610 --> 01:42:38,190 It's a very time limited problem that, you know, it might be a useful service for a year or two, but then thereafter it's not. 910 01:42:38,670 --> 01:42:42,049 You know, COVID vaccinations are not going to be going on large scale next year. 911 01:42:42,050 --> 01:42:44,580 And so therefore. Is there a business case for it? 912 01:42:45,380 --> 01:42:51,060 And we tried to get the news involved, you know, as if the news would publish some stories about it. 913 01:42:51,510 --> 01:42:54,629 But, you know, they didn't they didn't want to take it at all. They didn't care. 914 01:42:54,630 --> 01:42:59,220 They didn't even return emails, which I was quite disappointed about. 915 01:42:59,230 --> 01:43:02,370 I thought it would have been a really nice, nice little thing. 916 01:43:05,130 --> 01:43:08,280 And then at this point, we we had another really interesting idea. 917 01:43:08,280 --> 01:43:11,810 This wasn't my idea, actually. Another individual got involved to this point. 918 01:43:11,820 --> 01:43:20,550 A mutual friend of both myself and Robert called Adam Barker, and they had an idea together for. 919 01:43:22,390 --> 01:43:26,440 A a service to reallocate spare vaccine doses at the end of the day. 920 01:43:27,160 --> 01:43:35,290 So I don't know if you remember, people were queuing up outside GP's to try and get a spare shot and this was happening all over the world. 921 01:43:35,530 --> 01:43:39,760 It's this basic principle of at the end of the day, we just need to get the vaccine in someone. 922 01:43:39,770 --> 01:43:45,210 It doesn't matter who. And they quite, quite understandably had the idea. 923 01:43:45,220 --> 01:43:48,280 Many other people around the world had the same idea of. 924 01:43:49,840 --> 01:43:58,510 If you could make a system, an online website where you an individual member of the public at the end of the day, logs onto the website, 925 01:43:58,510 --> 01:44:08,559 puts in their address and gets told there are three spare doses this GP or they are to over that as you could do this really short notice allocation. 926 01:44:08,560 --> 01:44:15,340 If the people who are completely flexible on time, who are happy to just stop work whenever and walk out the door, 927 01:44:15,880 --> 01:44:19,630 it would be an ideal system and it would avoid people having to queue for hours. 928 01:44:20,770 --> 01:44:27,850 And so we we actually at this point started building a prototype of that, even though vaccine itself was still completely unfunded. 929 01:44:28,870 --> 01:44:35,110 We started building a prototype of this other one. And we we spent a few days on that. 930 01:44:35,860 --> 01:44:41,950 And then when we first brought it to the attention of the NHS, they basically said no, 931 01:44:42,610 --> 01:44:53,350 it would require a level of coordination that is not possible in the NHS at this time, which is basically the answer that we got. 932 01:44:53,860 --> 01:44:59,260 In particular, a company called Cure X were handling all the vaccine booking. 933 01:45:00,290 --> 01:45:09,670 They are a private company and they want the contract to manage the vast majority of vaccine appointment booking. 934 01:45:10,150 --> 01:45:16,540 And so I think for our system to have worked, it would have required a deal of integration with secure access. 935 01:45:17,320 --> 01:45:19,920 That was just not going to happen. 936 01:45:19,940 --> 01:45:30,520 Basically, it is a great shame it didn't happen because someone in France had the same idea and he built it and he's called David Meadows, 937 01:45:30,760 --> 01:45:39,400 which means quickly my dose. And he was awarded the Order of Merit for it very soon afterwards. 938 01:45:39,880 --> 01:45:43,930 So when I read that paper, then that was all right. 939 01:45:44,620 --> 01:45:51,470 We wanted to do that anyway and seek some recognition for both your project. 940 01:45:51,500 --> 01:45:55,270 So we should say that because it said a lot about compensation. 941 01:45:55,270 --> 01:46:03,220 So far it's been a little on the downbeat side, but that there have been awards of that not that was an award for the Oxford U.S. 942 01:46:04,120 --> 01:46:09,340 Institute of Engineering and Technology Global Challenge Grand Innovation Award. 943 01:46:09,610 --> 01:46:17,160 I believe it was called which which was a lovely surprise because we, I myself did not know we were in the running for that. 944 01:46:17,170 --> 01:46:21,420 So that was nice. And the vaccine at. 945 01:46:23,300 --> 01:46:27,140 No, not to my knowledge. And I must have been thinking of the Austin fun. 946 01:46:27,380 --> 01:46:35,810 Yeah, not to my knowledge. And so we were having these conversations with with different parts of the NHS. 947 01:46:37,260 --> 01:46:47,010 This is a important aspect of the way the UK health care system is structured is, you know, 948 01:46:47,290 --> 01:46:53,880 we talk about the NHS, but in reality there is no NHS, there is no monolithic NHS. 949 01:46:54,480 --> 01:47:01,200 What there is, is a large number of closely related but slightly independent groupings. 950 01:47:01,920 --> 01:47:05,880 So you have NHS England, for example, you have NHS Digital. 951 01:47:05,910 --> 01:47:11,760 You'd have thought that that was a very obvious place for for this vaccine project to be parked. 952 01:47:11,790 --> 01:47:21,000 NHS Digital, that was NHS X, which is the innovation section of the NHS and introductions were made for us. 953 01:47:21,330 --> 01:47:33,060 Lots and lots of people were. Very generously exerting themselves on our part to try and get the powers that be to take notice of this thing. 954 01:47:33,540 --> 01:47:36,570 And we weren't even trying to sell it to the NHS. 955 01:47:36,600 --> 01:47:42,850 We were not trying to sell the whole system to them. We would have happily gifted it to them. 956 01:47:43,630 --> 01:47:49,840 We were simply looking for a sum of around £10,000 to just cover the costs. 957 01:47:50,110 --> 01:47:57,360 Because I did some calculations and I calculated the £10,000 would more than cover all the costs we could foreseeably hit. 958 01:47:58,510 --> 01:48:03,280 And that's not even including any payment for the time that Rob and I put into it. 959 01:48:03,310 --> 01:48:07,360 It just covers the actual costs of the running it and. 960 01:48:08,360 --> 01:48:13,340 Eventually even. They went all the way to Patrick Vallance. 961 01:48:13,760 --> 01:48:20,030 I have an email from Patrick Vallance on my phone that I got forwarded and forwarded saying, 962 01:48:20,030 --> 01:48:26,270 look, can can vaccination not resource this and he just sent forwarded to vaccination needs. 963 01:48:26,300 --> 01:48:30,920 Thanks for bringing my to my attention and unfortunately nothing ever came of that. 964 01:48:31,460 --> 01:48:38,540 And in essence the way it went is every single conversation we had with people in the 965 01:48:38,540 --> 01:48:43,880 NHS would be along the lines of This is lovely and we really should resource this. 966 01:48:44,360 --> 01:48:57,169 But it's not in my purview to do so. No one was willing to take responsibility and I think a big part of that is because because conventionally 967 01:48:57,170 --> 01:49:03,240 primary care is actually one of the bits of the NHS that is more privatised than the rest. 968 01:49:03,260 --> 01:49:05,780 GP surgeries are actually independent businesses. 969 01:49:06,920 --> 01:49:16,610 So when you have something that is very explicitly geared towards primary care but has this national level strategic value, 970 01:49:18,110 --> 01:49:21,259 no one knows what to make of it and they don't know where to fit it in. 971 01:49:21,260 --> 01:49:30,860 And it obviously it didn't make sense to go around asking individual GP's to pay for it on an individual basis because look, I'm not going to do that. 972 01:49:31,430 --> 01:49:36,169 I'm not going to set up shop as an individual, calling around, making sales and booking all of it. 973 01:49:36,170 --> 01:49:42,229 I've got better things to do. So that's why we just wanted someone in the middle to give us the lump sum of money. 974 01:49:42,230 --> 01:49:54,020 And then then the more we spoke to the NHS, the more they started asking difficult questions around data security and and privacy. 975 01:49:54,470 --> 01:49:59,990 And from the beginning, we've been very I had been very careful around the way I wrote the code. 976 01:50:00,440 --> 01:50:05,620 At this point. I'd already had the experience with Oxfam, so I was much more aware of the, 977 01:50:06,100 --> 01:50:11,750 the implications of writing code that is used in a large scale medical context. 978 01:50:12,770 --> 01:50:22,700 So I believe we'd made many I had made many reasonable attempts to take care of the data privacy and the security aspects of it. 979 01:50:23,770 --> 01:50:33,129 And furthermore, there is guidance online from from the Information Commissioner's Office that quite clearly states that there are no privacy 980 01:50:33,130 --> 01:50:39,670 concerns around what we were doing because we were just using postcodes and postcodes and not regarded as identifying information. 981 01:50:40,900 --> 01:50:45,130 The problem is again dealing with an organisation like the NHS. 982 01:50:46,000 --> 01:50:53,410 You will get asked this question over and over and over again and people don't really they're not willing to take yes for an answer. 983 01:50:54,100 --> 01:51:01,360 They'll take they'll ask the question because, you know, it is their responsibility to do so, which is understandable. 984 01:51:01,660 --> 01:51:05,709 They must always be critical of a new technology that comes in front of them. 985 01:51:05,710 --> 01:51:08,410 They must look at it quite carefully and you can understand that. 986 01:51:09,400 --> 01:51:18,670 But none of them are really willing to take yes for an answer, because if you take yes for an answer, you're that implicitly taking responsibility. 987 01:51:18,910 --> 01:51:27,250 You yourself, you are the person who said, okay, I believe this is acceptable and they don't really want that decision tied to them. 988 01:51:28,330 --> 01:51:33,790 So I then spend hours joining phone calls with various information, 989 01:51:33,790 --> 01:51:39,310 leads across different sections of the NHS, answering the same question again and again and again. 990 01:51:40,690 --> 01:51:45,310 But they would never respond to my answers and say, okay, yes, I'm satisfied. 991 01:51:46,120 --> 01:51:50,760 They would just. They basically just let the conversation die. 992 01:51:51,870 --> 01:51:57,840 And that is why at no point did any section of the NHS ever encourage the uptake of vaccine out. 993 01:51:58,170 --> 01:52:01,590 Never did they condone it, Never did they resource it? 994 01:52:01,590 --> 01:52:05,640 Never. Did they recommend it to be used at primary care level? 995 01:52:06,030 --> 01:52:12,750 Instead, we were adopted entirely by a grassroots effort, word of mouth. 996 01:52:13,770 --> 01:52:17,220 And in the end the people who funded it were the UK Army. 997 01:52:17,490 --> 01:52:22,440 The Ministry of Defence put the money in because they had seconded. 998 01:52:24,030 --> 01:52:29,580 Military medics had been seconded to vaccination teams that were roving around the country. 999 01:52:30,620 --> 01:52:36,680 That was it was called Operation Script was the the Army's contribution to COVID response. 1000 01:52:37,430 --> 01:52:44,720 And because all of the military vaccination teams had adopted vaccine, that they were all using it of their own initiative. 1001 01:52:45,990 --> 01:52:50,900 Eventually, the person who heads up medical innovation within the army, 1002 01:52:52,250 --> 01:53:02,210 it was him who he who took the initiative and he found the money for us because it was so useful to what the army were doing. 1003 01:53:04,460 --> 01:53:08,030 Mm. So if you want a decision taken, go to the army. 1004 01:53:09,850 --> 01:53:13,160 No, They are in the business of making decisions. Yes, indeed. Yeah. 1005 01:53:13,640 --> 01:53:18,120 No, he was. Who knows? Maybe I'll cross paths with him again. 1006 01:53:18,830 --> 01:53:25,190 But it was. He's one of the few people who is willing to stick his neck out and make a decision. 1007 01:53:26,060 --> 01:53:32,150 And it just baffles me. And by the time the money landed, I think I was close to £3,000 in debt. 1008 01:53:32,690 --> 01:53:35,870 Me as an individual, unpaid drawing. 1009 01:53:35,870 --> 01:53:39,770 No salary. Not having a job. Just having a stipend. 1010 01:53:40,010 --> 01:53:43,130 And I'm bankrolling part of the UK's vaccination effort. 1011 01:53:43,580 --> 01:53:48,590 And no one cares. No one wants to listen within the NHS. 1012 01:53:49,160 --> 01:53:52,350 No one wants to do anything. And the sums of money that are involved. 1013 01:53:52,370 --> 01:53:57,049 A trivial. Absolutely. And when you hear these two, it well, 1014 01:53:57,050 --> 01:54:01,640 it must make you absolutely furious when you hear these stories of multi-billion 1015 01:54:01,760 --> 01:54:06,140 pound contracts handed out to private companies of one kind or another. 1016 01:54:06,320 --> 01:54:13,620 So yeah, we spoke to there was an individual at the Royal College of GPS, the Informatics Lead at the Royal College of GPS. 1017 01:54:14,120 --> 01:54:18,049 And he he made some good efforts to help us. And it was very telling. 1018 01:54:18,050 --> 01:54:23,330 At one point he said, you know what, if you were a consultancy, we buy this off for you for 5 million. 1019 01:54:24,560 --> 01:54:29,240 But you're not a consultancy, so we're not going to buy off you and nor are we going to deal with you. 1020 01:54:30,200 --> 01:54:35,810 And the NHS just does not have the the processes are not in place for engaging. 1021 01:54:37,080 --> 01:54:41,280 Like that. They're very familiar with dealing with consultants. 1022 01:54:41,280 --> 01:54:46,889 They know how to do that. The commercial department will draw up a contract and legal will swing in and the 1023 01:54:46,890 --> 01:54:51,390 process is there and they do it all day long and they waste loads of money by doing so. 1024 01:54:52,380 --> 01:54:56,400 But as soon as there's any kind of grassroots innovation, particularly ironically, 1025 01:54:56,400 --> 01:55:05,270 given that Rob is a military medic, so Rob is half in the NHS anyway, that kind of process just does not exist. 1026 01:55:05,280 --> 01:55:08,520 They do not know how to comprehend it and how to engage with it. 1027 01:55:09,550 --> 01:55:16,510 Mm hmm. So now you're you've moved on to the next stage in your in your life? 1028 01:55:17,050 --> 01:55:20,740 Yes. Yeah. What are you working on now? 1029 01:55:21,640 --> 01:55:27,490 So now I am working with Michael Chappell, my supervisor from Oxford, 1030 01:55:28,060 --> 01:55:37,210 and we are in the process of spinning out a company, a medical imaging company, which is related to. 1031 01:55:38,430 --> 01:55:42,569 Well, part of the work I did during my Ph.D. will be in the company, 1032 01:55:42,570 --> 01:55:50,670 but what I did in my Ph.D. is just the latest in a long line of research efforts that have been made in the group. 1033 01:55:51,180 --> 01:55:59,850 And and it's that long line, that body of historical research that we've done that we're we're now looking to commercialised sites. 1034 01:56:00,450 --> 01:56:05,579 It is an imaging company mainly focussed on the brain at this moment in time. 1035 01:56:05,580 --> 01:56:17,010 But maybe we'll be able to spread out in the future and we will be addressing to, to areas of application. 1036 01:56:17,460 --> 01:56:20,650 So. One of them will be clinical trials. 1037 01:56:21,640 --> 01:56:29,080 So hopefully we believe our type of MRI can be very useful in drug discovery. 1038 01:56:30,480 --> 01:56:36,420 And in fact, the day we are recording this, the 6th of December 2022. 1039 01:56:37,710 --> 01:56:42,510 Just recently there's been a lot of discussion around the first Alzheimer's drug. 1040 01:56:42,780 --> 01:56:45,750 Yes. That has significant positive evidence behind it. 1041 01:56:46,380 --> 01:56:56,580 And and this is very interesting because Alzheimer's is one of the holy grails in disease research at the moment. 1042 01:56:57,300 --> 01:57:00,000 And. We hope. 1043 01:57:01,050 --> 01:57:08,850 And when I say we, we as the collective community of people around the world who work on asylum, because there are many, many, many of us. 1044 01:57:09,570 --> 01:57:17,730 And we hope that ESL will be extremely useful in the context of Alzheimer's and. 1045 01:57:18,620 --> 01:57:24,440 We hope that it will be very sensitive to the early signs of Alzheimer's. 1046 01:57:25,730 --> 01:57:31,219 And this this is quite interesting in the context of the drug that's just come 1047 01:57:31,220 --> 01:57:38,780 through because that drug has been entirely developed around pet pets imaging. 1048 01:57:39,980 --> 01:57:44,780 So the drug on emission tomography, I guess we should spell it out. 1049 01:57:45,110 --> 01:57:48,120 Yes. Yes. 1050 01:57:48,120 --> 01:57:53,600 It's a nuclear imaging techniques that involves the use of radioactivity and. 1051 01:57:54,670 --> 01:57:59,170 The the drug that's just been just been reported on. 1052 01:57:59,170 --> 01:58:04,870 I think it's called like minimap lacuna map. I'm terrible with drug names. 1053 01:58:05,080 --> 01:58:08,920 I'm glad I did. Memorable, aren't they? 1054 01:58:09,370 --> 01:58:12,879 Yeah. And there is a reason. And now there are monoclonal antibody. 1055 01:58:12,880 --> 01:58:18,420 That's. That's. Most of the new ones seem to do that right where you have that knowledge. 1056 01:58:18,430 --> 01:58:23,320 I did not notice that you will be able to qualify that in the debate of drug discovery myself. 1057 01:58:23,980 --> 01:58:33,610 And so the one that's just going through, it's it targets the the plaques, the amyloid plaque. 1058 01:58:34,480 --> 01:58:41,290 And and this is important because it fits under the amyloid hypothesis, 1059 01:58:41,290 --> 01:58:46,719 which is remains controversial, although now this is more evidence for I guess. 1060 01:58:46,720 --> 01:58:52,420 But the the amyloid hypothesis is one explanation of how Alzheimer's comes about. 1061 01:58:53,560 --> 01:59:00,790 And therefore, under the amyloid hypothesis, if your drug can remove the amyloid plaques from the brain, 1062 01:59:01,270 --> 01:59:04,480 that will alleviate the symptoms of the disease. 1063 01:59:04,690 --> 01:59:10,059 That's the thinking. And the drug does that and it reduces the amyloid. 1064 01:59:10,060 --> 01:59:17,020 And I think the figure they reported is about 27% improvement in cognitive function. 1065 01:59:18,130 --> 01:59:28,330 And the reason why this is all interesting in the context today is so the MRI we're working with is the missing link in all of this. 1066 01:59:28,330 --> 01:59:34,900 Good news is that for the treatment to be successful, it has to start early. 1067 01:59:35,620 --> 01:59:47,949 Yes, to start really quite early. And at the moment, there remains no good systematic way of screening for the early signs of Alzheimer's. 1068 01:59:47,950 --> 01:59:55,630 The way that they do it at the moment is either doing a CSF sample, which involves taking small amounts of fluid from the body. 1069 01:59:56,110 --> 02:00:02,720 So that's an invasive procedure. Or they do a pet image of positron emission tomography. 1070 02:00:03,350 --> 02:00:07,520 And that also involves injecting the body with a radioactive compound. 1071 02:00:07,610 --> 02:00:15,260 So these techniques are they're well understood that say they're not challenging per say, 1072 02:00:15,860 --> 02:00:21,259 but they're labour intensive and you could never run a screening program at national scale on that. 1073 02:00:21,260 --> 02:00:26,510 And they said it's just too much work. And so this is where the big hope is for MRI. 1074 02:00:26,510 --> 02:00:33,320 That MRI could hopefully be used to run a screening program to pick up the early signs of Alzheimer's, 1075 02:00:33,800 --> 02:00:37,460 and then you could put them on a treatment pathway using this new drug. 1076 02:00:38,480 --> 02:00:45,260 So so the fact that we now have a treatment in place or it looks like we have a fast treatment in place, Alzheimer's, 1077 02:00:45,830 --> 02:00:54,020 it may increase demand for the screening technology to then identify the patients, because at the moment, 1078 02:00:54,350 --> 02:01:01,610 one reservation that you hear in the UK, it's quite a cynical and depressing points of view, 1079 02:01:01,610 --> 02:01:10,220 but is understandable is there is no point screening for Alzheimer's because if we find it, we can't do anything. 1080 02:01:10,580 --> 02:01:17,480 Yep. So why would you bother? But now maybe the calculus has shifted in the other direction. 1081 02:01:17,560 --> 02:01:21,610 So this is an interesting project. Companies very small at the moment. 1082 02:01:22,030 --> 02:01:32,870 It's just me and the supervisor. We're applying for funding early next year, so if we get that, then the company will exist and. 1083 02:01:34,180 --> 02:01:38,340 And I think it will remain. Who knows? 1084 02:01:38,350 --> 02:01:40,989 I mean, maybe it will be very successful and take off very quickly. 1085 02:01:40,990 --> 02:01:47,890 But I think it will always remain quite a tight knit company, actually, because we have a company called Quantified Imaging. 1086 02:01:48,670 --> 02:01:51,670 It's the name of the company, but we haven't even registered yet. All right. 1087 02:01:52,180 --> 02:01:55,270 The company is just a twinkle in our collective eyes at this moment in time. 1088 02:01:57,940 --> 02:02:05,230 Yeah, it will be interesting to work in a team again and I do enjoy working in the same room. 1089 02:02:05,560 --> 02:02:09,070 That was definitely the upside of. 1090 02:02:10,800 --> 02:02:17,060 The upside of oxtail. And the upside of having done vaccine was that. 1091 02:02:18,620 --> 02:02:23,720 I gained ten years worth of career experience and three months. 1092 02:02:24,700 --> 02:02:29,460 The the level of work that I had to just suddenly jump up to. 1093 02:02:30,130 --> 02:02:39,760 I personally authored many of the reports that went to the MHRA regulator in the UK, and I did a lot of the data analysis. 1094 02:02:39,760 --> 02:02:43,150 I believe some of them went to an FDA submission in the US. 1095 02:02:43,900 --> 02:02:50,710 So yeah, I mean, in a very short period of time I gained ten years worth of career experience and. 1096 02:02:52,730 --> 02:02:56,870 I learned a lot about how much I'm worth, actually, as well in the context of work. 1097 02:02:57,320 --> 02:03:00,860 Not that I'm a millionaire at this instance. I'm definitely not that. 1098 02:03:01,640 --> 02:03:08,150 But yes, that. I'm sorry that I shouldn't use the word unique because it's probably not unique, 1099 02:03:08,150 --> 02:03:14,930 but being able to acquire that level of experience is what he had experience working in an academic context. 1100 02:03:14,930 --> 02:03:24,889 And then you had to liaise with both clinical researchers and then clinical practitioners, and then also with a medical device manufacturing company. 1101 02:03:24,890 --> 02:03:28,310 So you see something about the commercial world and then also with government and 1102 02:03:28,310 --> 02:03:37,400 regulatory bodies that that universe of experience must be extraordinarily unusual for, 1103 02:03:37,400 --> 02:03:40,670 as you say, a 20 year old in the second year of that field. 1104 02:03:41,030 --> 02:03:46,030 Yeah, I think I'm. You're right. It's not completely unique, but it's almost unique. 1105 02:03:46,570 --> 02:03:50,110 A few other individuals were in that similar situation. 1106 02:03:51,100 --> 02:03:55,840 There was undoubtedly there was a silver lining to go that for me. 1107 02:03:56,500 --> 02:04:06,280 I also I didn't get COVID and to Christmas of last year, actually, I managed to avoid it for almost two years before I finally got COVID. 1108 02:04:06,820 --> 02:04:14,379 Now, I usually ask everybody how frightened they were of getting it, and the onset tends to scale by age. 1109 02:04:14,380 --> 02:04:20,050 So obviously people who are older or who have co-morbidities are more likely to have been quite frightened about getting it, 1110 02:04:20,050 --> 02:04:24,150 but in younger people, less so. I don't know how you felt initially. 1111 02:04:25,000 --> 02:04:32,320 Yeah, initially I wasn't too frightened. So that really was the very first period. 1112 02:04:32,440 --> 02:04:37,870 And then and then by the time I was doing oxygen and stuff, I was like, Fair enough. 1113 02:04:37,910 --> 02:04:43,140 It doesn't look. It doesn't look as harmless as was initially made out. 1114 02:04:44,160 --> 02:04:48,960 And then by the time I did get it, I was I was vaccinated at that point. 1115 02:04:49,440 --> 02:04:56,310 And I almost certainly had I believe I was the data was the wave going through at the time. 1116 02:04:57,090 --> 02:05:03,180 And I was supposed to go to France for Christmas because I'm French. 1117 02:05:03,180 --> 02:05:12,750 Half of my family is in France and I was supposed to go out there and then just before going, I finally fell ill with it and. 1118 02:05:14,170 --> 02:05:20,020 I'm pleased that I didn't get it earlier because it definitely knocked me out for a few days. 1119 02:05:20,290 --> 02:05:23,759 It's not. Not a pleasant experience. Who knows? 1120 02:05:23,760 --> 02:05:28,650 Maybe on the very first wave. The severity would have been different. 1121 02:05:28,660 --> 02:05:34,240 But but by the time I was vaccinated and I had it, yeah, I really knew I had it. 1122 02:05:34,580 --> 02:05:39,380 Yeah. Did you have experience of friends, colleagues, or family members having it? 1123 02:05:39,500 --> 02:05:43,460 Having severe illness with it? Being badly affected. 1124 02:05:43,850 --> 02:05:48,230 I am. So I think. 1125 02:05:49,850 --> 02:05:53,630 Yeah. I believe my mum lost her sense of smell for a while. 1126 02:05:57,340 --> 02:06:00,620 And. I only know of one. 1127 02:06:01,930 --> 02:06:08,090 Person. Let's say an acquaintance who he was a model in college. 1128 02:06:09,090 --> 02:06:15,360 Who died. And. That was very sad, actually, because a. 1129 02:06:17,720 --> 02:06:25,580 He was a person. For which he reacted very badly to two lockdowns. 1130 02:06:27,170 --> 02:06:30,500 And I became incredibly anxious. 1131 02:06:32,170 --> 02:06:36,760 And didn't handle it well at all. And then he puts on a lot of weight. 1132 02:06:37,990 --> 02:06:43,090 We're talking 30, 40% of his body weight he gained in that period of time. 1133 02:06:43,990 --> 02:06:52,960 And then tragically, it was a week before his first vaccination was due April. 1134 02:06:53,940 --> 02:06:56,100 21 may be May 21. 1135 02:06:56,970 --> 02:07:06,570 He caught COVID, and by this point, I think he was so obese, you know, he'd taken on so much weight that he died very soon afterwards. 1136 02:07:06,990 --> 02:07:12,300 It's a classic case of the co-morbidity COVID and obesity is quite well established, I believe. 1137 02:07:12,990 --> 02:07:18,180 And I didn't know him as an individual in any meaningful sense. 1138 02:07:18,180 --> 02:07:21,720 I just knew him as someone around college. But. 1139 02:07:23,500 --> 02:07:30,120 Yeah I'm very much of the opinion he. He's one of those people that lockdown killed inadvertently. 1140 02:07:31,200 --> 02:07:36,810 Which is not. I'm not going to turn that into a broader argument of lockdown was the wrong course of action to take. 1141 02:07:36,840 --> 02:07:42,110 I genuinely don't know. That question is is too big of a question for me to to pronounce upon. 1142 02:07:42,120 --> 02:07:48,600 I'm not qualified that some he I firmly believe he's one of those inadvertent. 1143 02:07:49,600 --> 02:07:58,450 Costs of lockdown. So I think we really need to just think what in summary, 1144 02:07:58,450 --> 02:08:05,829 what would you say are the key lessons that you're going to take forward in in how you plan 1145 02:08:05,830 --> 02:08:11,200 your life and career in future from the time you spent working on these COVID projects? 1146 02:08:11,770 --> 02:08:16,330 I think the vaccine map taught me that nothing is ever so simple and so obvious. 1147 02:08:17,380 --> 02:08:27,730 That it hasn't already been tried. I unless Rob had been able to point to people on Twitter saying, I need help for this right now, 1148 02:08:27,940 --> 02:08:32,409 I would have never even started working on that because I would have thought, no, it's a solved problem. 1149 02:08:32,410 --> 02:08:35,410 It's done, not needed. But there you go. 1150 02:08:35,410 --> 02:08:38,710 Nothing is ever so simple and so obvious that it shouldn't be tried. 1151 02:08:40,150 --> 02:08:45,570 And from Oxfam's. Yeah. 1152 02:08:45,610 --> 02:08:49,460 From Oxford. There are no adults in the room. I firmly stand by that conclusion. 1153 02:08:49,480 --> 02:08:56,920 And in the future, I. I believe I want to leave the UK for a period of time and go and live and work abroad. 1154 02:08:57,220 --> 02:09:01,760 And. And experience something a bit different. 1155 02:09:01,770 --> 02:09:07,499 I don't think I'm going to find a utopia anywhere. I don't think anywhere is a paragon of that being well-run. 1156 02:09:07,500 --> 02:09:18,240 But I think the UK is afflicted by an inability to to critically look in upon itself and address the problems that are here, 1157 02:09:19,140 --> 02:09:26,850 where we're very good at deflecting and blaming everything but ourselves, I believe, and in COVID that really came home to roost. 1158 02:09:32,100 --> 02:09:32,580 Great.
