Question

What Is Compliance And Stiffness?

Answer 1

Compliance:

1. The change in volume relative to the change in pressure is referred to as compliance.
2. In a compliant heart, there might be an increase in volume with a significant change in pressure.
3. To avoid pulmonary congestion, diastole causes the ventricles to fill with enough blood at a low enough pressure.

Stiffness:

1. Stiffness is a measurement of pressure change vs volume change.
2. To allow for a bigger capacity, a stiff heart increases pressure over usual.
3. Pressure is excessively high for the amount of volume in stiffer ventricles.
4. Compliance and stiffness are inversely proportional.
