 In blood, O2 exists in two forms:Dissolved in plasma.Combined with hemoglobin.

 O2 is poorly soluble, so the majority of O2 in the blood is carried in combination with hemoglobin (Hb).

 Oxygen content of the blood (CaO2) is calculated as the sum of the O2 bound by Hb and that dissolved in the plasma. Note: PaO2 is expressed in mmHg.

 Oxygen delivery to tissues (DO2) is a function of the arterial O2 content (CaO2) and cardiac output.DO2 (ml/min) = Cardiac Output (l/min) x CaO2 (ml/l)Note: it is important to convert CaO2 to (ml/l)
