- Cardiac output
- The amount of blood that is pumped by the heart per minute. 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 a minute. That is the cardiac output, the amount of blood the heart pumps through the circulatory system in a minute.
* * *cardiac out·put -'au̇t-.pu̇t n the volume of blood ejected from the left side of the heart in one minute called also minute volume
* * *(CO) the effective volume of blood expelled by either ventricle of the heart per unit of time (usually volume per minute); it is equal to the stroke volume multiplied by the heart rate.
