Question

Cardiac output is given by:

• A. $\text{SV}\times \text{HR}=5L/m$
• B.
  $SV\times HR=500ml$
• C.
  $SV\times HR=72ml/m$
• D.
  $SV\times HR=70ml/m$

Answer 1

The correct option is A $\text{SV}\times \text{HR}=5L/m$

The stroke volume (SV) multiplied by the heart rate (HR) (no. of beats per min.) gives the cardiac output. Therefore, the cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and averages 5000 mL or 5 liters in a healthy individual.
