WebThe delivery of oxygen (DO 2) to the myocardium (oxygen supply) is determined by two factors: coronary blood flow (CBF) and the oxygen content (concentration) of the arterial blood (CaO 2 ). O 2 Delivery = CBF × CaO 2 where CBF = mL/min and CaO2 = mL O2/mL blood Therefore, the units for O 2 delivery are mL O 2 /min.
