Figure 4. Cardiac Power Output (CPO) in Cardiogenic Shock
CPO is calculated as the product of mean arterial pressure (MAP) × CO/451 (a
correction factor to convert units into watts of energ y). In the SHOCK trial, a higher
CPO was associated with lower in-hospital mortality. Reprinted with permission from
