Why does venous PO2 decrease in anemic hypoxia? Shouldn't it be constant as PO2 is a measure of the dissolved oxygen?

  • The linked reference to the condition states why. "The amount of functional hemoglobin is too small, and hence the capacity of the blood to carry oxygen is too low". Can you please explain what you don't quite understand? Then we hopefully can explain it to you – Chris Rogers May 17 at 6:01
