WebAug 1, 2010 · The state of arterial blood oxygenation is determined by the PaO 2. This reflects gas exchange in the lungs and normally the PaO 2 decreases with age. This is due to decreased elastic recoil in the lungs in the elderly, thereby yielding a greater ventilation-perfusion mismatch. WebOct 29, 2024 · The PAO 2 calculation is an estimated value using the following equation: PAO2 = FiO2 (PB-PH2O) – PaCO 2 /RQ FiO 2 = concentration of oxygen the patient is breathing PB = barometric pressure (usually kept at 760 mmHg) PH 2 O = partial pressure of water vapor (assumed to be 47 mmHg)
