1 00:00:03,590 --> 00:00:02,070 hi everybody josh byerly here in mission 2 00:00:05,670 --> 00:00:03,600 control houston i'm joined by my friend 3 00:00:08,070 --> 00:00:05,680 ed powers who is a flight surgeon here 4 00:00:09,589 --> 00:00:08,080 at nasa and you know we talk a lot about 5 00:00:11,270 --> 00:00:09,599 uh experiment work and what the crew is 6 00:00:12,789 --> 00:00:11,280 doing they do quite a bit of human 7 00:00:14,310 --> 00:00:12,799 research and things like that on their 8 00:00:15,669 --> 00:00:14,320 own bodies while they're up there but 9 00:00:17,189 --> 00:00:15,679 figured you know a good chance to get a 10 00:00:19,269 --> 00:00:17,199 flight surgeon in here and actually 11 00:00:20,390 --> 00:00:19,279 talk about you know what you do first of 12 00:00:21,590 --> 00:00:20,400 all as a flight surgeon because it's a 13 00:00:23,590 --> 00:00:21,600 whole lot more than i think what people 14 00:00:25,109 --> 00:00:23,600 realize and also you know what are some 15 00:00:27,109 --> 00:00:25,119 of the difficulties of dealing with a 16 00:00:28,230 --> 00:00:27,119 crew member who's not here on earth so 17 00:00:30,790 --> 00:00:28,240 first of all welcome thank you for 18 00:00:33,430 --> 00:00:30,800 joining us talk just a minute about what 19 00:00:35,270 --> 00:00:33,440 you do on a just a daily basis okay well 20 00:00:36,709 --> 00:00:35,280 uh flight surgeons are 21 00:00:38,790 --> 00:00:36,719 kind of critical to 22 00:00:40,229 --> 00:00:38,800 maintaining the you know the status 23 00:00:42,549 --> 00:00:40,239 health status of the crew members by 24 00:00:45,270 --> 00:00:42,559 monitoring them basically 25 00:00:47,110 --> 00:00:45,280 every day we um 26 00:00:48,389 --> 00:00:47,120 the folks who are assigned to crew 27 00:00:50,470 --> 00:00:48,399 members to 28 00:00:52,470 --> 00:00:50,480 look out for them and um on a weekly 29 00:00:53,910 --> 00:00:52,480 basis we interview them and make sure 30 00:00:55,990 --> 00:00:53,920 for about 15 minutes at a time make sure 31 00:00:57,670 --> 00:00:56,000 they're doing well in orbit but really 32 00:00:58,709 --> 00:00:57,680 begins about two years before they 33 00:01:00,549 --> 00:00:58,719 launch 34 00:01:02,389 --> 00:01:00,559 the flight surgeons who are assigned to 35 00:01:04,149 --> 00:01:02,399 an astronaut basically get to know them 36 00:01:05,509 --> 00:01:04,159 very well and help in their training so 37 00:01:07,670 --> 00:01:05,519 that they know what to do in a medical 38 00:01:09,270 --> 00:01:07,680 emergency on board the space station i 39 00:01:12,230 --> 00:01:09,280 think with various training sessions 40 00:01:13,590 --> 00:01:12,240 including running cardiac resuscitation 41 00:01:15,030 --> 00:01:13,600 and uh and go through various 42 00:01:16,710 --> 00:01:15,040 simulations 43 00:01:18,149 --> 00:01:16,720 and uh so this allows us to get to know 44 00:01:19,830 --> 00:01:18,159 the crew members very well and we 45 00:01:21,429 --> 00:01:19,840 develop a relationship a very good 46 00:01:23,510 --> 00:01:21,439 working relationship with them an amount 47 00:01:24,310 --> 00:01:23,520 of trust you know that goes along with 48 00:01:25,510 --> 00:01:24,320 that 49 00:01:27,190 --> 00:01:25,520 what do they what do they have up on 50 00:01:28,469 --> 00:01:27,200 orbit i mean they got you know the crew 51 00:01:30,230 --> 00:01:28,479 healthcare basically what amounts to a 52 00:01:31,670 --> 00:01:30,240 mini hospital on board but talk about i 53 00:01:33,590 --> 00:01:31,680 mean because you can't just run down to 54 00:01:35,109 --> 00:01:33,600 the drugstore and get you know 55 00:01:36,710 --> 00:01:35,119 get some ibuprofen or something if you 56 00:01:38,390 --> 00:01:36,720 need it so how well are they stocked 57 00:01:40,069 --> 00:01:38,400 what do they have up there well they 58 00:01:41,910 --> 00:01:40,079 have a variety of commonly used 59 00:01:45,109 --> 00:01:41,920 medicines you know tylenol and various 60 00:01:46,630 --> 00:01:45,119 other things are there but we also have 61 00:01:48,870 --> 00:01:46,640 medicines that we think 62 00:01:50,389 --> 00:01:48,880 could be useful in case some potential 63 00:01:51,030 --> 00:01:50,399 emergencies could occur you know we have 64 00:01:52,149 --> 00:01:51,040 the 65 00:01:53,910 --> 00:01:52,159 advanced cardiac life support 66 00:01:55,190 --> 00:01:53,920 medications on board they're trained 67 00:01:57,030 --> 00:01:55,200 with and 68 00:01:59,190 --> 00:01:57,040 in various antibiotics and things that 69 00:02:01,030 --> 00:01:59,200 we think might be necessary if something 70 00:02:02,950 --> 00:02:01,040 were to happen up there 71 00:02:05,429 --> 00:02:02,960 so talk as a doctor how you know doctors 72 00:02:06,870 --> 00:02:05,439 use a lot of their their senses their 73 00:02:09,190 --> 00:02:06,880 sight their hearing they listen you know 74 00:02:10,550 --> 00:02:09,200 the dutch you don't have any of that 75 00:02:13,030 --> 00:02:10,560 really you know one of your crew members 76 00:02:14,070 --> 00:02:13,040 250 miles up in space going around the 77 00:02:15,750 --> 00:02:14,080 earth so 78 00:02:17,110 --> 00:02:15,760 how difficult is that what what kind of 79 00:02:18,869 --> 00:02:17,120 challenges do you have well there's a 80 00:02:20,070 --> 00:02:18,879 bit of a challenge and that's part of 81 00:02:21,510 --> 00:02:20,080 part of the reason why we developed such 82 00:02:23,910 --> 00:02:21,520 a close relationship with them in this 83 00:02:26,630 --> 00:02:23,920 pre-launch time frame in the training is 84 00:02:29,110 --> 00:02:26,640 because uh we get to know sort of 85 00:02:30,869 --> 00:02:29,120 what they're capable of of doing and how 86 00:02:33,030 --> 00:02:30,879 and what their experience level is and 87 00:02:35,670 --> 00:02:33,040 how they approach a problem when it 88 00:02:37,110 --> 00:02:35,680 comes to medical issues and so so it is 89 00:02:39,030 --> 00:02:37,120 a little bit of a challenge but at the 90 00:02:41,830 --> 00:02:39,040 same time as we get to know them very 91 00:02:43,030 --> 00:02:41,840 closely we're able to to trust their 92 00:02:44,949 --> 00:02:43,040 eyes and ears 93 00:02:46,630 --> 00:02:44,959 and uh work with them to try to diagnose 94 00:02:48,309 --> 00:02:46,640 any issues that go unfortunately they 95 00:02:50,630 --> 00:02:48,319 tend to be extremely healthy when we 96 00:02:52,229 --> 00:02:50,640 launch them which is very helpful 97 00:02:54,070 --> 00:02:52,239 but occasionally something will come 98 00:02:55,190 --> 00:02:54,080 come about and of course we have the 99 00:02:57,190 --> 00:02:55,200 luxury once in a while having a 100 00:02:59,110 --> 00:02:57,200 physician astronaut on board right and 101 00:03:00,070 --> 00:02:59,120 uh that makes our jobs quite a bit 102 00:03:02,309 --> 00:03:00,080 easier 103 00:03:04,070 --> 00:03:02,319 so let's talk about we were out i guess 104 00:03:05,430 --> 00:03:04,080 it was a couple weeks ago out at the 105 00:03:06,470 --> 00:03:05,440 national space biomedical research 106 00:03:08,070 --> 00:03:06,480 institute here in houston they just 107 00:03:09,509 --> 00:03:08,080 opened up a brand new facility here and 108 00:03:12,149 --> 00:03:09,519 there's a lot of scientists there and 109 00:03:14,149 --> 00:03:12,159 and doctors and these phds talking about 110 00:03:15,830 --> 00:03:14,159 miniaturization and 111 00:03:17,350 --> 00:03:15,840 you know from what i understand that we 112 00:03:18,790 --> 00:03:17,360 used to have a very large ultrasound 113 00:03:20,869 --> 00:03:18,800 cart onboard the station that took up an 114 00:03:22,630 --> 00:03:20,879 entire rack and now we've got things 115 00:03:23,670 --> 00:03:22,640 down to basically the size of a laptop 116 00:03:25,190 --> 00:03:23,680 so 117 00:03:27,270 --> 00:03:25,200 talk a little bit about how the space 118 00:03:28,789 --> 00:03:27,280 station and you know you know we sort of 119 00:03:30,390 --> 00:03:28,799 force ourselves to go small and go 120 00:03:31,910 --> 00:03:30,400 efficient how does that lead to better 121 00:03:34,550 --> 00:03:31,920 stuff here on earth for for hospitals 122 00:03:36,229 --> 00:03:34,560 and things like that well uh of course 123 00:03:37,750 --> 00:03:36,239 smaller is better when it comes as long 124 00:03:41,270 --> 00:03:37,760 as you can keep the same fidelity 125 00:03:42,949 --> 00:03:41,280 smaller is better and uh and as far as 126 00:03:44,789 --> 00:03:42,959 keeping track of inventory and launching 127 00:03:46,630 --> 00:03:44,799 into orbit that sort of thing from our 128 00:03:48,149 --> 00:03:46,640 standpoint is very helpful 129 00:03:49,509 --> 00:03:48,159 but there are remote applications as 130 00:03:51,030 --> 00:03:49,519 well you know there are places in the 131 00:03:52,070 --> 00:03:51,040 world where you just can't get medical 132 00:03:53,589 --> 00:03:52,080 care 133 00:03:55,589 --> 00:03:53,599 at the level that you would see say in 134 00:03:57,110 --> 00:03:55,599 houston right so to have a remote 135 00:03:59,429 --> 00:03:57,120 capability of something small and 136 00:04:01,270 --> 00:03:59,439 transportable is very helpful when you 137 00:04:03,509 --> 00:04:01,280 get out away from civilization a bit 138 00:04:04,869 --> 00:04:03,519 yeah how much do the crew members do uh 139 00:04:06,470 --> 00:04:04,879 you know basically finding out about how 140 00:04:07,910 --> 00:04:06,480 their own bodies react to being in space 141 00:04:10,149 --> 00:04:07,920 and and what is that going to teach us 142 00:04:11,509 --> 00:04:10,159 going on i mean you know is it the more 143 00:04:12,869 --> 00:04:11,519 that we investigate it the more we learn 144 00:04:14,390 --> 00:04:12,879 i mean is there more mysteries because 145 00:04:15,509 --> 00:04:14,400 you know we've talked about how we've 146 00:04:17,110 --> 00:04:15,519 even learned that the immune system 147 00:04:18,949 --> 00:04:17,120 reacts differently being up there with 148 00:04:20,629 --> 00:04:18,959 no gravity so what what do we learn 149 00:04:21,909 --> 00:04:20,639 that's true there's a number of 150 00:04:23,670 --> 00:04:21,919 research 151 00:04:25,189 --> 00:04:23,680 studies going on associated with 152 00:04:26,390 --> 00:04:25,199 universities that are looking at the 153 00:04:27,909 --> 00:04:26,400 immune system and there's a little bit 154 00:04:30,150 --> 00:04:27,919 of a decreased immune response when you 155 00:04:31,909 --> 00:04:30,160 get on orbit you know tendency to to 156 00:04:33,350 --> 00:04:31,919 maybe be a little bit more susceptible 157 00:04:35,830 --> 00:04:33,360 to getting a cold or something along 158 00:04:36,710 --> 00:04:35,840 those lines there are also bone density 159 00:04:38,390 --> 00:04:36,720 issues you know as you go in 160 00:04:39,909 --> 00:04:38,400 microgravity 161 00:04:41,430 --> 00:04:39,919 gravity is not pulling down on the bones 162 00:04:44,310 --> 00:04:41,440 it's not the stimulation there to keep 163 00:04:47,030 --> 00:04:44,320 bones healthy so we have learned how to 164 00:04:50,150 --> 00:04:47,040 supplement that by doing daily exercise 165 00:04:52,469 --> 00:04:50,160 both aerobic and resistive exercise that 166 00:04:54,310 --> 00:04:52,479 seems to be helping to mediate that 167 00:04:56,310 --> 00:04:54,320 problem with bone density and muscle 168 00:04:58,310 --> 00:04:56,320 weakness 169 00:05:00,550 --> 00:04:58,320 and then of course we recently have come 170 00:05:02,390 --> 00:05:00,560 across an issue with eyes and vision 171 00:05:03,990 --> 00:05:02,400 changes in space that 172 00:05:05,909 --> 00:05:04,000 we have gotten a little bit more detail 173 00:05:07,670 --> 00:05:05,919 understanding what's going on there as 174 00:05:09,749 --> 00:05:07,680 far as fluid shifting towards the 175 00:05:11,510 --> 00:05:09,759 towards the head when gravity is not 176 00:05:13,830 --> 00:05:11,520 pulling it down anymore it 177 00:05:14,790 --> 00:05:13,840 seems to affect the fine structures of 178 00:05:17,350 --> 00:05:14,800 the eye 179 00:05:19,270 --> 00:05:17,360 and produce potentially 180 00:05:20,790 --> 00:05:19,280 permanent changes in the vision and so 181 00:05:22,150 --> 00:05:20,800 we've been using some instrumentation up 182 00:05:23,189 --> 00:05:22,160 there now that hasn't been up there 183 00:05:25,189 --> 00:05:23,199 before 184 00:05:28,469 --> 00:05:25,199 small size ultrasonography look at the 185 00:05:29,670 --> 00:05:28,479 eye there's also a very high level 186 00:05:31,430 --> 00:05:29,680 optical camera that we're going to be 187 00:05:33,029 --> 00:05:31,440 flying soon that will be able to take a 188 00:05:35,270 --> 00:05:33,039 really good look at the back of the eye 189 00:05:37,510 --> 00:05:35,280 and try to assess the issues there we 190 00:05:39,590 --> 00:05:37,520 think it could be 191 00:05:41,590 --> 00:05:39,600 could be related to fluid shifting along 192 00:05:43,029 --> 00:05:41,600 with high salt diet that happens to be 193 00:05:44,790 --> 00:05:43,039 on the space station due to the fact 194 00:05:46,790 --> 00:05:44,800 that the food has to be 195 00:05:49,029 --> 00:05:46,800 preserved for a long time up there and 196 00:05:50,230 --> 00:05:49,039 uh maybe carbon dioxide levels may have 197 00:05:51,510 --> 00:05:50,240 something to do with this we try to keep 198 00:05:52,870 --> 00:05:51,520 the carbon dioxide levels down there are 199 00:05:54,950 --> 00:05:52,880 a number of factors that we're looking 200 00:05:56,629 --> 00:05:54,960 at up there that may affect 201 00:05:58,710 --> 00:05:56,639 certain situations here on earth you 202 00:05:59,830 --> 00:05:58,720 mentioned exercise uh have you guys seen 203 00:06:01,430 --> 00:05:59,840 a difference in you know the crew 204 00:06:03,029 --> 00:06:01,440 members coming back i mean it's one of 205 00:06:05,350 --> 00:06:03,039 the people that goes over to russian 206 00:06:07,749 --> 00:06:05,360 kazakhstan we spent many an hour on uh 207 00:06:09,189 --> 00:06:07,759 helicopters helicopters and airplanes 208 00:06:10,870 --> 00:06:09,199 going over there but have you guys seen 209 00:06:12,230 --> 00:06:10,880 a difference in 210 00:06:13,430 --> 00:06:12,240 now that you've got sort of a variety of 211 00:06:15,510 --> 00:06:13,440 different exercise equipment up there 212 00:06:16,790 --> 00:06:15,520 the crew members exercise quite a bit 213 00:06:18,550 --> 00:06:16,800 during the day do you see a difference 214 00:06:20,390 --> 00:06:18,560 now whenever they're coming back and how 215 00:06:22,309 --> 00:06:20,400 their body's reacting yes definitely 216 00:06:23,590 --> 00:06:22,319 they're many of them are coming back and 217 00:06:25,110 --> 00:06:23,600 even a little bit better shape than when 218 00:06:27,430 --> 00:06:25,120 they launched because they get a little 219 00:06:28,790 --> 00:06:27,440 distracted the first i mean the last 220 00:06:30,390 --> 00:06:28,800 month or so before they launch and 221 00:06:31,590 --> 00:06:30,400 sometimes exercise falls off so when 222 00:06:33,350 --> 00:06:31,600 they get up there 223 00:06:36,070 --> 00:06:33,360 and they have a concentrated exercise 224 00:06:37,909 --> 00:06:36,080 program daily exercise program you know 225 00:06:39,749 --> 00:06:37,919 at least an hour of resistive exercise 226 00:06:42,790 --> 00:06:39,759 at least an hour of cardiovascular 227 00:06:44,070 --> 00:06:42,800 workout every day then sometimes uh they 228 00:06:46,469 --> 00:06:44,080 they actually come back in a little bit 229 00:06:48,390 --> 00:06:46,479 better shape now i think we finally over 230 00:06:50,390 --> 00:06:48,400 the years and many crews i think we 231 00:06:52,230 --> 00:06:50,400 finally have got the right approach to 232 00:06:53,510 --> 00:06:52,240 this and uh we've got the right exercise 233 00:06:55,589 --> 00:06:53,520 equipment on board and they're actually 234 00:06:56,950 --> 00:06:55,599 doing very well that's good so talk a 235 00:06:57,909 --> 00:06:56,960 bit about your background i mean we get 236 00:06:59,830 --> 00:06:57,919 this question all the time how did you 237 00:07:02,230 --> 00:06:59,840 get the job at nasa so how do you go 238 00:07:04,150 --> 00:07:02,240 from medical school into being being a 239 00:07:06,550 --> 00:07:04,160 flight surgeon well i grew up in the 240 00:07:08,710 --> 00:07:06,560 chicago area and so i went to medical 241 00:07:10,469 --> 00:07:08,720 school at rush university in chicago and 242 00:07:12,790 --> 00:07:10,479 i was very interested in surgery and 243 00:07:14,870 --> 00:07:12,800 emergency medicine and so i did a 244 00:07:16,790 --> 00:07:14,880 post-graduate training program first 245 00:07:18,230 --> 00:07:16,800 general surgery internship 246 00:07:19,510 --> 00:07:18,240 and then two additional years of 247 00:07:21,670 --> 00:07:19,520 emergency medicine and became an 248 00:07:23,909 --> 00:07:21,680 emergency medicine specialist and it 249 00:07:25,589 --> 00:07:23,919 just so happens i've always had the 250 00:07:27,990 --> 00:07:25,599 fondness of flying i started flying when 251 00:07:30,629 --> 00:07:28,000 i was 15 yeah with a friend's airplane 252 00:07:32,550 --> 00:07:30,639 and so i was trying to combine those 253 00:07:34,950 --> 00:07:32,560 different interests emergency medicine 254 00:07:37,510 --> 00:07:34,960 and flying and space program and i 255 00:07:39,589 --> 00:07:37,520 wound up doing another residency program 256 00:07:41,110 --> 00:07:39,599 in aerospace medicine two-year program 257 00:07:43,990 --> 00:07:41,120 in dayton ohio 258 00:07:45,589 --> 00:07:44,000 and uh eventually wound up in nasa so 259 00:07:47,189 --> 00:07:45,599 i've been working as an emergency 260 00:07:49,350 --> 00:07:47,199 physician and an aerospace medicine 261 00:07:51,510 --> 00:07:49,360 physician for uh much of the last 10 or 262 00:07:54,390 --> 00:07:51,520 15 years it's still fascinating to you 263 00:07:55,909 --> 00:07:54,400 oh yes very much so lots to learn yeah 264 00:07:57,749 --> 00:07:55,919 well thanks for joining us it's dr ed 265 00:07:58,950 --> 00:07:57,759 powers one of the flight surges here at 266 00:08:00,390 --> 00:07:58,960 nasa if you would like to learn more 267 00:08:01,670 --> 00:08:00,400 about all these different types of 268 00:08:03,430 --> 00:08:01,680 experiments that the the crew is 269 00:08:04,469 --> 00:08:03,440 actually doing on a daily basis about 270 00:08:06,070 --> 00:08:04,479 you know with their own bodies and how 271 00:08:07,350 --> 00:08:06,080 the human body reacts to being in space 272 00:08:11,749 --> 00:08:07,360 you can always log on to the nasa 273 00:08:15,110 --> 00:08:13,589 station just click on research and take
