Question

what is the cardiac output of a person whose pulse is 80 beats per minute with a stroke volume of 60 milliliters per beat?

Answer 1

Answer and Explanation:

Cardiac output is calculated as the product of heart rate and stroke volume. Stroke volume can be calculated as LVOT area x LVOT VTI. In this example, stroke volume is 60 ml. Therefore, if the heart rate is 90 beats/min, the cardiac output is 90 beats/min x 60 ml/beat = 5400 ml/min or 5.4 L/min.
