- Grimburger 4y agoYou sure about that? Humans regularly work at 30x atmospheric pressure and can probably go to 100x https://space.stackexchange.com/questions/32640/what-is-the-maximum-atmospheric-pressure-a-human-can-tolerate https://space.stackexchange.com/questions/32640/what-is-the-...
- afterburner 4y agoThese seem to talk mostly about diving, where you breathe from a regulated air supply. I assume that air supply is not at 30-100x atmospheric pressure?
- bboygravity 4y agoIf the air supply wouldn't be at a slightly higher pressure than that, the air would get sucked out of your lungs as far as I understand. This is why dive tanks run out way way faster the deeper you go (around 1 hour at 18 meters deep and around 10 minutes at 30+ meters out the top of my head).
- heavenlyblue 4y agoAir supply is at that pressure, but they don't breathe the same mix as atmospheric air. Atmospheric air becomes narcotic at 4 atmospheres.
- Grimburger 4y agoThe air is at that pressure, as is the surrounding water pressure on the human body. We are remarkably good at handling higher pressures.
- mattashii 4y agoI don't think airplane hulls are designed for more than 1 Atm of pressure differential between cabin and the outside; according to the wikipedia article [0] on cabin pressurization normal values are between 540 and 690 hPa pressure differential are normal. If the cabin has an overpressure event, the hull might pop like a balloon, leading to a decompression event.
