Stroke Volume Calculator


The stroke volume calculator helps you calculate the stroke volume, body surface area, cardiac index, and stroke volume index.

Enter your cardiac output, heart rate, height, and weight to calculate the stroke volume and the index.

In case you don’t know, Cardiac output, or CO, is the amount of blood the heart pumps through the systemic circulation in a minute.

CO = SV x HR

Stroke volume (SV) is the blood pumped from the left ventricle during each systolic cardiac contraction.

HR is the heart rate.

Stroke Volume Index (SVI) compares SV to body surface area (BSA), so it can compare how well the heart works to how big a person is.
