Cardiac Output

Cardiac output is the amount of blood pumped by the heart per minute and is measured in millilitres of blood per minute. In order to calculate cardiac output you have to times stroke volume (millilitres per beat) by heart rate (bpm).
The average person will have a stroke volume of about 70ml/min and a heart rate of 70bpm, cardiac output would be as follows:

70 x 70 =4,900ml of blood per minute.

This means that 4,900 ml of blood is being pushed out of the left ventricle per minute, which is equivalent to how much blood an average person has in their circulatory system. This measurement is a normal person at rest. During exercise cardiac output can increase up to 7 times.

Cardiac output is a measure of the amount of blood pumped around the body every minute. Blood carries all the essential nutrients that the body needs to function. If cardiac output is low then it could be a sign of cardiac disease, and as a result the body will not be getting the nutrients it need to function properly. This makes measuring cardiac output an important indicator of potential cardiac health problems.
