Cardiac Power Output (CPO)

Cardiac power output (Fincke 2004): (MAP x cardiac output) / 451 in watts, against the 0.6 W cardiogenic-shock threshold.

Example

Mean arterial pressure
80 mmHg
Cardiac output
5 L/min

Result: Cardiac power output 0.89 W, above the 0.6 W cardiogenic-shock threshold (Fincke).

The tool opens with these values already filled in. Replace them with your own.

What the result means

Threshold
CPO < 0.6 W was the strongest independent hemodynamic predictor of in-hospital mortality in cardiogenic shock.

What you enter

  • Mean arterial pressure
  • Cardiac output
How this is calculated
Formula
CPO = (MAP x cardiac output) / 451, in watts (451 converts mmHg.L/min to watts).
