The partial pressure of alveolar oxygen (PAO₂)when the atmospheric pressure is 3 atmospheric pressure (atm),the PACO₂ is 40 mm Hg,and the FɪO₂ is 0.80 is _____ mm Hg.

Question

Quizplus · Accepted Answer

PAO₂ = (Pbₐᵣ - PH₂O)FɪO₂ - PaCO₂ ÷ 0.8; Pbₐᵣ = 3 atm * 760 = 2280 mm Hg.
PAO₂ = (2280 - 47)0.8 - 40 ÷ 0.8.
PAO₂ = 1786.4 - 50 = 1736.4 mm Hg.
