Enter the cardiac index (L/min/m^2) and the mean arterial pressure (mmHg) into the Calculator. The calculator will evaluate the Cardiac Power Index.

## Cardiac Power Index Formula

CPI = CI * MAP / 451

Variables:

- CPI is the Cardiac Power Index (W/m^2)
- CI is the cardiac index (L/min/m^2)
- MAP is the mean arterial pressure (mmHg)

To calculate Cardiac Power Index, multiply the cardiac index by the mean arterial pressure, then divide by 451.

## How to Calculate Cardiac Power Index?

The following steps outline how to calculate the Cardiac Power Index.

- First, determine the cardiac index (L/min/m^2).
- Next, determine the mean arterial pressure (mmHg).
- Next, gather the formula from above = CPI = CI * MAP / 451.
- Finally, calculate the Cardiac Power Index.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

cardiac index (L/min/m^2) = 14

mean arterial pressure (mmHg) = 12
