Pressurizing Life

Life without the bends...


"The bends" are a serious issue for deep-sea divers. What will the gases in our bodies do with prolonged exposure to various pressures from Jupiterian flying settlements or lunar colonies? We have an idea with some environments (the earth, our own shuttles, and the ISS). But what gases may be toxic in these extra-terrestrial environments?


Nitrogen under pressure builds up in the diver's body, so the diver uses a mix with less nitrogen in it. Are we going to find that pressure differentials in new environments is causing the same issue with oxygen, hydrogen, or some other gas we commonly breath on earth?


Unfortunately, I do not have the answers. Perhaps someone will soon.
