Cardiac output, also known as heart output is the amount of blood your heart pumps each minute.
Sufficient cardiac output helps keep blood pressure at the levels needed to supply oxygen-rich blood to your brain and other vital organs.
The normal range for cardiac output is about 4 to 8 L/min, but it can vary depending on the body’s metabolic needs.
Formula to calculate cardiac output.
Stroke volume is the volume of blood pumped from the left ventricle per beat.
Heart rate is the speed of the heartbeat measured by the number of contractions of the heart per minute.
Example:
If a patient’s stroke volume is 80 ml with each contraction and his heart rate is 70 beats/minute, Calculate the patients cardiac output.
Therefore, the patients cardiac output is 5,600 ml/minute.
