A patient with a gunshot wound arrived via ambulance at the ER with Hb 4g%,SaO₂ 98% on F_IO₂ 1.0 and PaO₂ of 503 mm Hg.What would her oxygen content equal?

Question

Quizplus · Accepted Answer

The oxygen content (CaO2) in blood is calculated using the formula: CaO2 = (Hb x 1.34 x SaO2) + (PaO2 x 0.003). Given Hb = 4g%, SaO2 = 98%, and PaO2 = 503 mm Hg, substituting these values gives: CaO2 = (4 x 1.34 x 0.98) + (503 x 0.003) = 5.24 + 1.51 = 6.75 vol% O₂, which is approximately 6.76 vol% O₂.
