Definition Delivery of oxygen can be calculated with the equation: DO2 = CO x CaO2 Where CaO2 = [1.34 x Hgb x SaO2] + [PaO2 x 0.003] The portion contributed by dissolved O2 [PaO2 x 0.003] is usually negligible except in cases of extreme anemia (i.e. Hgb 5) or carbon monoxide poisoning. Factors that affect […]
