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).
