Cardiac Power Output Calculator — MAP × CO / 451

Calculate Cardiac Power Output (CPO) using the formula CPO = MAP × CO / 451 to assess global cardiac work capacity, with CPO <0.6 W being the strongest predictor of in-hospital mortality in cardiogenic shock.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate Cardiac Power Output (CPO) using the formula CPO = MAP × CO / 451 to assess global cardiac work capacity, with CPO <0.6 W being the strongest predictor of in-hospital mortality in cardiogenic shock

Each component has a specific meaning:

  • Formula CPO = MAP × CO / 451 — The formula cpo = map × co / 451 recorded for the scenario being assessed.

Note: Interpret the cardiac power output result against the thresholds and context described above.

How to Use

Enter the formula CPO = MAP × CO / 451 for the scenario you are assessing. Calculate Cardiac Power Output (CPO) using the formula CPO = MAP × CO / 451 to assess global cardiac work capacity, with CPO <0.6 W being the strongest predictor of in-hospital mortality in cardiogenic shock. Use the cardiac power output result to inform your calculation.
