With regard to ascending to high altitudes:

Question

TuteeHUB · Accepted Answer

in permanent residents of the Andes, arterial and venous PO2 is half normal levels

TuteeHUB · Answer

there is a linear decrease in inspired oxygen pressures with increasing altitude

TuteeHUB · Answer

the partial pressure of water vapour in moist inspired air decreases with PiO2

TuteeHUB · Answer

at 19,200m, barometric pressure = 47mmHg, PiO2 then is approx 9mmHg

TuteeHUB · Answer

at peak at Mt Everest, barometric pressure = 380mmHg, PiO2 is approx 70mmHg
