The arterial oxygen content (CaO₂)for a patient with PaO₂ 100 mm Hg,SaO₂ 95%,and hemoglobin 15 g/dL is _____ mL oxygen/dL.
A) 19.4
B) 1909.8
C) 210
D) 21.05

Question

Quizplus · Accepted Answer

A hemoglobin level of 15 divided by 100 equals 0.15.Multiply by 1.34 mL and then multiply by saturation on 95%.The result is 19.1% oxyhemoglobin.Then add 0.3% volume dissolved in plasma to get the total content of oxygen/dL.The arterial blood oxygen content is the amount of oxygen carried in the arterial blood.1909.8 is an incorrect answer if the formula is followed correctly.210 is incorrect when the formula is applied correctly.21.05 is an incorrect response if the formula is applied correctly.
