aye mate, make sure you keep your nasal cavaties clear of the flappy region and you should have adequate air
Aye, but I speak of major hypoxia here mate
Yesterday, I was at Andrews Air Force Base, and a bunch of my pilot classmates and I got to into a decompression chamber where they took us into altitudes up to 25,000 ft and got experience hypoxia. Once up there we took our oxygen masks off and had to do math problems, circle numbers in sequential order etc. all the while noting our various symptoms. Funny thing is, I was doing my work and I look up to see that everyone's put their masks back on because they got dizzy, nauseas, tunnel vision, or what ever they experienced but I hadn't felt anything and I was like "What the hel is wrong with everyone, I don't feel anything" So the 'instructor' outside on the mic, asked me if I was feeling anything and I was like "nope!". So then he wanted to me to start counting down from 99 by three's. Lol now, I dono if it was because my math sucked or what, but the counting went horrible and everyone was laughing, and at the end he asked me again if I was feeling anything and I said no again. Anyway, the only time I felt anything was the last seconds before putting on the oxygen. I felt as if I was high lol, everything felt slow and repetitive, kinda like an instant deja vu.
Anyway, it was a fun experience. The whole purpose was to realize our hypoxic symptoms so that if we were in a situation like it, we could realize that we were getting hypoxic and to descend in altitude or whatever. I asked my dad, whose a doctor, and he said that my late reaction might be because I am naturally less susceptible to hypoxia...I dono ,but it was pretty cool.
