Cardiac output generated during cardiopulmonary resuscitation (CPR) is inversely proportional to the oxygen deficit (ml O2/min). Recall that oxygen deficit is defined as: (basal metabolic oxygen consumption − oxygen extracted from alveoli). In this case, the oxygen deficit was 155 ml O2/min, which extrapolates to a cardiac output during CPR of 39% of baseline.
