How much air pressure can a human survive?

A person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air – divers do it. If they are breathing air, the limit is just a handful of atmospheres.

How many atmospheres can a human handle?

NCBI provides a short paper with a theoretical limit of 1000m for humans, based on data we have collected from saturation divers to date. That would be 100atm of pressure. Somewhere in between is the claimed record for deep diving which is roughly 600m. Slightly higher than that, we find synthetic testing of Hydreliox.

How many atmospheres of pressure can a human withstand?

A person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air-divers do it. If they are breathing air, the limit is just a handful of atmospheres. Not sure exactly how many it takes before oxygen becomes toxic, though.

How much air can a human Breathe in the ocean?

Provided there is pure oxygen available, a human can still breathe in around 12.2 \% sea level air pressure. At the other extreme, the normal atmosphere which is referred to as 1 (atmosphere) is exceeded by deep sea divers to an amazing extent. I believe the record is 33 atmospheres whereas 3 would stress most of us.

How much psi can a human withstand?

Offer him 10,000 psi via a stick of dynamite, however, and his bodily response will be significantly less comfortable. And do you intend to have this person breathing air? A person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air – divers do it.

How much oxygen is in the atmosphere at 4000 meters?

The earth’s atmosphere contains 20.9\% oxygen, but the critical factor is its partial pressure. At sea level (1 Bar) this equates to 150mm Hg, but at 4000m it’s down to 70mm. Hg. At this altitude (as in some Andean communities) it’s just about impossible to have babies, though children will survive.
