Question

If the HR is 72 bpm and the SV is 72 mL, the cardiac output would be approximately equal to...

1) 5.2 liters/minute
2) 144 mL/minute
3) neither of these choices are correct

Answer 1

The cardiac output can be calculated by multiplying the stroke volume by the heart rate. In this case, the cardiac output would be approximately 5.2 liters/minute.

Step-by-step explanation:

The cardiac output (CO) is the volume of blood pumped by each ventricle in one minute. It is calculated by multiplying the stroke volume (SV) by the heart rate (HR).

In this case, the given HR is 72 bpm and the SV is 72 mL. So, the cardiac output would be:

CO = HR x SV
CO = 72 bpm x 72 mL
CO = 5184 mL/min

In liters per minute, this would be approximately 5.2 liters/minute.
