Web16 nov. 2024 · How to calculate alveolar gas equation ( PaO2 )? PH2O is vapour pressure of water at 37°C and is equal to 47 mmHg (760 mmHg – 47 mmHg). The respiratory quotient or respiratory coefficient (RQ) is the ratio of CO2 eliminated divided by the O2 consumed, and its value is typically 0.8 (RQ = CO2 eliminated / O2 consumed). WebIn summary, PaO2 is determined by alveolar PO2 and the state of the alveolar-capillary interface, not by the amount of hemoglobin available to soak them up. PaO2, in turn, determines the oxygen saturation of hemoglobin (along with other factors that affect the position of the O2-dissociation curve, discussed below).
