Cardiac Output Print E-mail

Dr. Kennedy Cardiac output is the amount of blood that is pumped by the heart per unit time, measured in liters per minute (L/min). The amount of blood that is put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume multiplied by the heart rate is the cardiac output. A normal adult's heart can easily pump 5 quarts (4.7 liters) of blood each minute. Therefore 4.7 liters (4700 cc) is the cardiac output - the amount of blood the heart pumps through the circulatory system in one minute. If the heart rate is 60 per minute, then each contraction of the ventricle moves and average of 4700/60, or 78.33 cc. A cc, or cubic centimeter is the same volume as an ml. or milliliter (1/1000 of a liter). Athletic training can increase the cardiac output.
