Fio2 and po2 ratio

WebSep 22, 2024 · The oxygenation factor (OF) (PaO2/[FiO2*MAP]) proposed and studied by EL Khatib et al. is a reciprocal of the oxygenation index (OI) ([FiO2*MAP]/PaO2) which is … WebThe partial pressure for oxygen at alveolar level (PAO2) is given by the alveolar air equation. PAO2 = (PB-PH2O) FIO2 – PACO2 x FIO2 + (1-FIO2/R) where R is the respiratory exchange ratio (VCO2/VO2; normally approximately 0.8). Simplifying for bedside use: PAO2 = 150 – PaCO2 x 1.25.
