I know human can't dive too deep because there's pressure difference between inside and outside of the body. But how much pressure can human withstand if human is breathing components that is surrounding him?
So I have two questions: 1.How much pressure can human handle if he is surrounded by regular air (also breathing air)? 2. How much pressure can human handle if he is floating in oxygen-rich liquid and breathing it at the same time (Liquid Breathing, Wikipedia)?
There's a similar question, but it doesn't have answer that fully satisfies me. Highest Pressure Human Body Can Survive In?
