Question

According to the concept of ventricular compliance, which of the following statements are true?

a. Increased compliance implies that for the same pressure, volume is smaller.

b. Decreased compliance implies that for the same pressure, volume is larger.

c Increased compliance implies that if volume is the same, pressure must be higher.

d. Increased compliance implies that for the same pressure, volume is larger.

e. Decreased compliance implies that if volume is the same, pressure must be lower.

Answer 1

Ventricular compliance is the ability of ventricles to accomodate large volume of blood with increase in pressure.   
If the ventricular compliance decrease, the pressure may rise but the volume may remain unchanged as seen in ventricular hypertrophy.
If the ventricular compliance increases, the volume in the ventricles rises but the pressure may remain unchanged.

So the correct statement is d. Increased compliance implies that for the same pressure, volume is larger.
