Cardiac Output

Cardiac output, called CO for short, is the amount of blood that flows out of the left ventricle per minute.  The easier way to define cardiac output is the amount of blood that leaves the heart each time the heart beats.

Why is Cardiac Output Important?

Cardiac output is extremely important as it is measuring the amount of blood that is being pump throughout the body.  If the cardiac output is too low, that means not enough blood is being pumped out of the heart.  When this occurs, the cells of the body are not receiving the oxygen they need to survive.  The body works EXCEPTIONALLY hard to maintain the correct cardiac output to keep the body alive and functioning.
