\[CPO=\frac{MAP \cdot CO}{451}\]
Variables
CPOcardiac power output (W)
MAPmean arterial pressure (mmHg)
COcardiac output (L/min)
Description
What is this formula?
Cardiac Power Output (CPO) is a comprehensive measure of cardiac performance that combines blood flow and arterial pressure. It represents the hydraulic power generated by the heart and is considered one of the strongest hemodynamic predictors of outcome in cardiogenic shock.
When to use it
Use this formula in critical care, cardiogenic shock assessment, advanced heart failure management, and cardiac catheterization studies.
Example
Data:
MAP = 90 mmHg
CO = 5.0 L/min
Formula:
CPO = (MAP × CO) / 451
Substitution:
CPO = (90 × 5.0) / 451
Result:
CPO = 1.00 W
Applications
- Cardiogenic shock evaluation
- Heart failure assessment
- Intensive care monitoring
- Mechanical circulatory support decisions
- Advanced hemodynamic analysis
