Distensibility Explained

Distensibility is a metric of the stiffness of blood vessels. It is defined as

D = (d _{sys} - d _{dias})/((p _{sys} - p _{dias} )d _{dias}) ,

where

d _{sys} and d _{dias} are the diameter of the vessel in systole and diastole, and p _{sys} and p _{dias} are the systolic and diastolic blood pressure.^[1]
