Definition Total O2 content is expressed by the following equation: O2 content (CaO2) = ([SaO2 x Hgb x 1.31 ml/dl blood]) + ([0.003 ml/dl blood per mmHg x PO2) where Hgb is hemoglobin concentration and SaO2 is hemoglobin saturation at the given PO2. Oxygen transport is dependent on both respiratory and circulatory function. Total O2 […]
