What is augmentation index?

The difference between the second and first systolic peaks is called augmentation index. It is expressed as a percentage of the pulse pressure.

What is the arterial compliance?

Compliance is the ability of an artery to increase the volume in response to a given increase in blood pressure.

What is pulse wave velocity?

PWV is the speed at which the pressure waveform travels (wave propagation) along the aorta and large arteries, during each cardiac cycle.

What is applanation tonometry?

The principle of applanation tonometry defines that the force acting on the plunger is proportional to the pressure in the artery when where the artery surface is flattened.
