Please don't regret the taking or the posting of this video. Everyone's read, probably numerous times, about the effects of hypoxia but unless you've spent time in an altitude chamber you probably haven't actually seen how it can sneak up on people and to what degree it can affect them. Your video is a valuable tool in my opinion. Quote Share this post Link to post Share on other sites

Even if you didn't want it posted, thank you. I bet there are many people who are now for the first time thinking very seriously about what the risks on high altitude jumps are.Skydiving: wasting fossil fuels just for fun.

Thank you ok, here's the deal. Go to: http://www.faa.gov/about/office_org/field_offices/fsdo/hou/ Open the "NASA Physiological Training" pdf file which details application procedures. You'll contact the Houston Flight Standards office @ 281-929-7000 and let them know you'd like to get into an altitude chamber class with NASA. The pdf. is fairly explanatory. If you run into probs, let me know. Buck Quote Share this post Link to post Share on other sites
Beerlight 0 #56 February 16, 2007 QuoteWith regard to pre-breathing, are you actually breathing pure oxygen? For those not aware, oxygen is toxic.Quote Prebreathing is with 100% oxygen. I've personally breathed pure oxygen via aviator oxygen mask for 8 hours straight on many many occasions. 4 hour prebreathe at ground level followed by 4 hours at 30,000 ft. (this was in an altitude chamber). Medical oxygen protocols are entirely different. And yes, breathing 100% below about 66 feet sea water pressure and you can experience oxygen toxicity quite rapidly.

It was clear the guy stumbling around was experiencing issues within 20 seconds after the video started. He acted as if he had a very high alcohol content in his blood. Yet, at least two jumpers that I saw sat back and let him stumble to the door then fall out backwards on his back. That is some irresponsible shit. Not only dangerous to their own lives, but the fact that they actually helped that jumper out the door is sickening. I find myself a little pissed off after watching that video. I've had good experiences with other jumpers on the plane in the 24 jumps I've participated in so far and everyone has acted pretty mature and responsible. I have faith and trust in other jumpers due to my experiences with them to date, to see something like this makes me want me to be more cautious about who is on the plane. Whoever that was helping that jumper out needs to be grounded for a long time and given a long speech. They were able to stand up and jump correctly out the door, but not able to see that person rolling on the floor like they were on LSD trying to get out the door was a very bad thing? Then again, I'm one of those people that believe no matter how intoxicated you are on a substance your aware enough of your actions to prevent them and be responsible for them. Don't get me wrong I'm also not one of those people that think we should stop skydiving, just because of the mishaps that do occur. All in all this community is more responsible and mature than any group of people I've ever met. I'm just glad and very suprised the jumpers that did get out made it down alive.

Right. They were as "drunk" as he was. That's the insidious part of hypoxia - you can't fix the problem if your judgement is so impaired that you can't think straight. Often, hypoxic people will fix on one goal (i.e. getting out the door, tuning a radio, fixing a gauge) to the exclusion of all else. One of the scariest stories I heard about hypoxia involved a pilot flying cross country alone at night. He was flying at 14,000 feet to clear some turbulence. He was going to stop enroute to refuel, but as he watched his fuel state he thought he could get to the next airport beyond that. He flew along a little longer. The fuel gauge still showed 1/4 of a tank, and he kept tapping it to see if the needle moved. It didn't. Heck, he could make it all the way home! He focused most of his attention on the fuel gauge, tapping it occasionally and watching it slowly drop. Fortunately, at some point ATC heard something in his voice, figured out what was going on, and told him to descend immediately. He argued a bit, then descended to 8000 feet. As he descended, he realized - holy shit! I have less than 30 minutes of fuel left and I'm over unlit mountainous terrain at night! He asked for help and made it safely to an airport. Afterwards he said that everything else - the need for a 45 minute reserve at night, whether the next airport had runway lighting, his calculations for range based on headwinds - had completely left his mind. The only thing he was thinking about was that fuel gauge - and as long as it was above 0 he was fine. The scary part was he was still functional enough to fly the airplane and use the radio. He was just hypoxic enough that flying all the way home sounded like a good idea. >Whoever that was helping that jumper out needs to be grounded >for a long time and given a long speech. He was no more responsible for what he was doing than the guy who couldn't stand up. Heck, the guy in the back appeared to be off O2 for longer than the guy who couldn't stand up - so it would stand to reason that he was _more_ impaired.
