Question: 1 / 400

What is the formula for calculating cardiac output?

CO = HR x SV

The formula for calculating cardiac output is CO = HR x SV, where CO represents cardiac output, HR is heart rate, and SV stands for stroke volume. This formula indicates that cardiac output is the product of how many times the heart beats per minute (heart rate) and the amount of blood pumped out of the heart with each beat (stroke volume).

This relationship is essential in understanding how the heart functions to meet the body's demands for oxygen and nutrients. When either heart rate or stroke volume increases, cardiac output will also increase, which is crucial during exercise or in situations where the body requires more blood flow. This formula is fundamental in cardiovascular physiology and is widely used in clinical settings to assess heart function and overall cardiovascular health.
