Question

Value of cardiac output is

• A. Auricular volume $\times$ ventricular volume
• B. Stroke volume $\times$ Rate of heart beat
• C. Blood pumped in one minute
• D. Both B and C.

Answer 1

The correct option is D Both B and C.

Cardiac output (CO) is the product of the heart rate (HR), i.e. the number of heartbeats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the ventricle per beat; thus, CO = HR × SV. Values for cardiac output are usually denoted as L/min.

So, the correct option is D.
