Full Answer
Santa Barbara City College defines cardiac output as the volume of blood pumped by the heart per minute. This is calculated as the heart rate multiplied by the stroke volume of blood pumped by the heart with each beat. The average person has a resting heart rate of 70 beats per minute, and a stroke volume of 70 milliliters per beat, according to SBCC. This equals a cardiac output of 4900 milliliters per minute.
