Question

You are given the following information on a patient
Blood volume= 5.2 L
Hematocrit = 47%
Hemoglobin Concentration = 12g/dl whole blood
Total amount of oxygen carried in blood = 1015 mL
Arterial Plasma Po2 = 100 mm Hg

You know that at a plasma Po2 of 100 mm Hg plasma contains .3 mL O2/dL, and that hemoglobin is 98% saturated. Each hemoglobin molecule can bind to a maximum of four molecules of oxygen. Using this information calculate the maximum oxygen-carrying capacity of hemoglobin (100% saturated)
Units will be mL O2/g Hb

Explanation / Answer

oxygen carrying capacity is 1.34 ml of oxygen per gram of hemoglobin....

taking amount of Hb mentioned in question as 12g/ dL , then oxygen carrying capacity for 100 ml of bood will be = 1.34*12 = 16.02 ml of oxygen approximately.
