Vascular Distensibility & Function

What is compliance?

The distensibility of the vessel
How does compliance affect volume and pressure of a vessel?
- High compliance: change in volume produces a small change in pressure
- Low compliance: change in volume produces a large change in pressure
How does blood pressure change with age? Which blood pressure changes the most?
- Blood pressure increases because arteries become less compliant
- Systolic increases the most
How does arteriosclerosis change blood pressure?

Increases systolic BP because reduces compliance
How does aortic stenosis change blood pressure?

Decreases systolic BP, may stay normal
How does a patent ductus arteriosus change blood pressure?

Decreases diastolic BP and increases systolic BP
How does aortic regurgitation change blood pressure?

Decreases diastolic BP and increases systolic BP
