- The amount of blood your heart pumps in one minute is called the cardiac output. Cardiac output is determined by this formula: s × p where s is the "stroke volume" and p is the pulse rate. The stroke volume is the amount of blood the heart squeezes out each time it beats. For a young teenager, the stroke volume is about 60 ml. Find your pulse. Use your pulse to figure out your cardiac output.
