A patient is receiving 0.30 FɪO₂ with a barometric pressure at 750 mm Hg.The partial pressure of carbon dioxide (PCO₂₎ for this patient is 70 mm Hg; the partial pressure of arterial oxygen (PaO₂)is 60 mm Hg.The PAO₂ for this patient is _____ mm Hg.

Formula: PAO₂ = (Barometric pressure [PB] - pressure of water vapor [PH₂O])FɪO₂ - PaCO₂ (1.25).
PAO₂ = (750 mm Hg - 47)0.30 - 70 (1.25).
PAO₂ = 210.9 - 87.5.
PAO₂ = 123.4 mm Hg.
