What's cardiac output?

Heart pump volume: The cardiac output is the volume of blood per minute pumped by the heart. Cardiac output is equal to heart rate multiplied by stroke volume (the volume of blood ejected with each heartbeat).

Amound of blood: The cardiac output is the amount of blood cycled through the heart each minute and is usually reported as litres per minute. It correlates with weight and to standardize the cardiac output it is divided by the body surface area in meters squared which is the cardiac index.
