WebDec 22, 2024 · The alveolar gas equation is used to calculate alveolar oxygen partial pressure: PAO2 = (Patm - PH2O) FiO2 - PACO2 / RQ. While PAO2 is the partial pressure of oxygen in the alveoli, Patm is the atmospheric pressure at sea level equaling 760 mm Hg. PH2O is the partial pressure of water equal to approximately 45 mm Hg. WebEach of these gases contributes to the total pressure of the air, the pressure that each gas contributes to the total is the partial pressure of that gas. For example, at sea level the total pressure is 760 mm Hg and oxygen makes up 21% of the gas, the partial pressure of oxygen in the atmosphere is 160 mm Hg (760 X 0.21 = 159.6). delphine wespiser ex compagnon
