At body temperature, how much oxygen will physically dissolve in plasma at a PO₂ of 40 mm Hg?

Question

Quizplus · Accepted Answer

At body temperature (37°C) and a partial pressure of oxygen (PO2) of 40 mm Hg, the amount of dissolved oxygen in plasma would be 0.12 ml/dl. This is based on the oxygen-dissociation curve, which shows that at a PO2 of 40 mm Hg, the dissolved oxygen content is approximately 0.3 ml/dl, but at body temperature, only one-third of this will physically dissolve in plasma, resulting in a value of 0.12 ml/dl.
