Question

How to calculate cardiac output?

Answer 1

Cardiac output:

1. The heart rate multiplied by the stroke volume gives the cardiac output.
2. The formula is given as CO = HR $\times$ SV.
3. It denotes the volume of blood being pumped out by the heart.
4. Heart rate is the number of times the heart beats in one minute.
5. Stroke volume is the volume of blood ejected from the left ventricle of the heart during each ventricular systole.
6. The normal range of cardiac output is 4 to 8L/min.
