Oxygen in Blood
Oxygen is carried in the blood in two forms. Most is carried combined with hemoglobin but there is a very small amount dissolved in the plasma. Each gram of hemoglobin can carry 1.31ml of oxygen when it is fully saturated. Therefore every litre of blood with a Hb concentration of 15g/dl can carry about 200mls of oxygen when fully saturated (occupied) with oxygen (PO2>100mmHg). At this PO2 only 3ml of oxygen will dissolve in every litre of plasma. When considering the adequacy of oxygen delivery to the tissues, three factors need to be taken into account, hemoglobin concentration, cardiac output and oxygenation.
