The highest elevation in the french alps is 15,771 feet above sea level. the barometric pressure is approximately 420 mm hg. (the barometric pressure at sea level is 760 mm hg.)
(a)-what is the fractional concentration of o2 (fio2) in atmospheric air at 15,771 ft?
(b)-what is the partial pressure of oxygen (po2) of humidified air?
(c)-how does this value of po2 compare with the po2 of humidified air at sea level?
