Stroke Volume * Heart Rate

Calculates total blood flow in Liters per minute. Usually normalized as Cardiac Index (CI) by body surface area.

SV 70mL, HR 70bpm -> CO 4.9 L/min.

Usually 4 to 8 Liters per minute at rest.

It is the Cardiac Output divided by the patient’s Body Surface Area (BSA), which adjusts for different body sizes.

Typically via echocardiogram or other cardiac imaging.
