 As stated, the ultimate responsibility of the cardiovascular system is to provide adequate oxygen to the working cells.

 CaO2 = ([Hb] × SaO2% × 1.36) + (PaO2 × 0.003)[Hb] = concentration of hemoglobin in the blood in gr/dlSaO2 = percent saturation of hemoglobin with oxygen1.36 = a constant (Hüfner's) describing the amount of oxygen bound by 1 g of HbPaO2 = the partial pressure of oxygen in arterial blood0.003 = the solubility coefficient of oxygen in blood (ml/mmHg of oxygen/dL of blood)

Note: The effect of decreases in [Hb] and SaO₂ on CaO₂ are shown in Box 3.1.
