Lung strength studies are commonly discussed on SCUBA forums. The general recommendation is not to risk more than 1.5PSI so as to leave a safety factor because lung health and conditioning make a large difference, but average maximum exhalation pressure of healthy adult men seems to be 2.5 to 2.75 psi if I'm interpreting the numbers correctly. thorax.bmj.com/content/thoraxjnl/47/11/961.full.pdf | |

Hypothermia wouldn't be an issue, easy enough to wrap up enough--I rejected suits for what they're made of, not for being bulky. Where are you getting the lung strength from? | |
| Jun 13, 2019 at 21:56 | comment | added | Perkins | Has oxygen-only ever been tested by anyone? The average human's lungs can withstand a 2-3 psi pressure differential and a human in good physical condition needs somewhat less than 2psi partial pressure of oxygen to remain conscious. I'd think nitrogen embolism (bends) or hypothermia from evaporating skin moisture would be the biggest issues, but it might well be possible to overcome them without a full suit with sufficient acclimatization and tolerance for pain... | |
