Human Lung Air Pressure - CR4 Discussion Thread

Web23 jul. 2008 · A normal person is capable of a breath pressure of 1-2 psi, so by pressure breathing you can increase your lung pressure from 10.1 psi to 11.1-12.1 psi during each exhale, closer to the 14.7 psi you are used to. I'm kind of just talking out my ass, but that's what I gathered from the bit of reading I did. Web5 mei 2024 · Wikipedia reports that 9.8 kPa = 1.4 psi is lung pressure that a typical person can exert. But I'm not exactly sure how it will relate to blowing into a small silicone tube. Also the fact that one of Honeywell sensors is measured in mbars is confusing. Why did they suddenly use mbars instead of psis?
