The arterial oxygen content (CaO₂) for a patient with PaO₂ 100 mm Hg, SaO₂ 95%, and hemoglobin 15 g/dl would be _____ ml oxygen/dl.

Question

Quizplus · Accepted Answer

The arterial oxygen content (CaO2) is calculated using the formula: CaO2 = (1.34 x Hb x SaO2) + (0.0031 x PaO2). Substituting the given values: CaO2 = (1.34 x 15 x 0.95) + (0.0031 x 100) = 19.095 + 0.31 = 19.405 ml/dl, which rounds to 19.4 ml/dl.
