CARDIAC OUTPUT

Written by

The volume of blood pumped out per minute by the ventricles of the heart. It is one measure of the heart’s efficiency. At rest, the heart of a healthy adult will pump between 2.5 and 4.5 litres of blood every minute. Exercise will raise this to as much as 30 litres a minute but, if this figure is low, it suggests that the heart muscle may be diseased or that the person has suffered severe blood loss.
