WebThe mean P/F change between FIO2 0.5 and 1 (Delta P/F) was 47% +/- 35%. Sixteen patients (67%) had a P/F >200 at FIO2 1 whereas P/F was <200 at FIO2 0.5. Venous admixture (Q(VA)/Q(T)) decreased linearly for each FIO2 step (p < 0.001). The Q(VA)/Q(T) change between FIO2 0.5 and 1 was strongly correlated with Delta P/F (r = 0.84). WebAlveolar gas equation: PAO2 = (FiO2 x [Patm - PH2O]) - PaCO2/RQ. FiO2 = fraction of inspired oxygen. Patm = atmospheric pressure: 760mmHg at sea level. PH2O = saturated vapor pressure of water: 47mmHg at body temperature of 37° Celsius. PaCO2 = the arterial partial pressure of CO2: normally 40mmHg. RQ = the respiratory quotient: normally 0.8.
