WebSpecific questions will ask you to calculate the alveolar PO2 (PAO2), the alveolar-arterial oxygen gradient [P (A-a)O2], and the physiologic deadspace (VD/VT ratio). Terms in this set (15) Which of the following will determine the partial pressure of oxygen in the alveolus? A. (Hb x 1.34 x SaO2) + (PaO2 x .003) B. (PaCO2 - PECO2) / PaCO2 Web17 aug. 2024 · The basic formula is: A-a oxygen gradient = PAO2 - PaO2. PaO 2 is measured by arterial blood gas, while PAO 2 is calculated using the alveolar gas …

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). Web28 jan. 2024 · What is the PO2 in dry air at a barometric pressure of 760 mmHg? 760 x 0.21 = 159.6. 24. How do you calculate the PO2 of humidified air? ...
