Web26 de jul. de 2024 · Mixed venous PCO2 is usually about 46 mmHg, and is determined by the total oxygen content of mixed venous blood and the shape of the CO 2 dissociation curve. The total CO2 content of mixed venous blood, which is usually about 520 ml/L, is described by the modified Fick equation: VCO2 = CO × k × (PvCO2 - PaCO2) where. WebPETCO2 correlated closely with the PaCO2 in the normal and acyanotic groups (r2 = 0.97 and 0.91, respectively) and the lines of regression for the relationship between PaCO2 and PETCO2 for both groups did not differ from the line of identity (P less than or equal to 0.05).
