Question

The partial pressure of O2 in lungs is approximately 100 torr where the fractional O2saturation of hemoglobin is about ______. The partial pressure of O2 in venous blood is about 30 torr and the saturation of hemoglobin with O2 is approximately ______.

[A] 0.95, 0.35
[B] 0.95, 0.55
[C] 2.8 torr, 26 torr [D] 0.91, 0.27

Answer 1

(D)0.91,0.27

A healthy person may usually saturate 90 to 99 perecent of oxygen in blood from the partial pressure  .So option D) is the answer.

opt A) to Opt C) were not relate 90 to 99 percent of the partial pressure in the given question.
