ABI\PVR (ankle brachial index\pulse volume recording) Test
These non-invasive tests are used as measurement comparisons to gauge the level of blood flow at various segments of the foot or ankle. ABI short for ankle brachial index is a method to record and compare the systolic blood pressure of the arm to the ankle.
PVR stands for the Pulse Volume Recording, which measures blood flow in the artery. TBI represent toe brachial index measures the blood pressure levels in the toe. In order to make the most accurate interpretation of a condition like Peripheral Vascular Disease, physicians combine all three tests to indicators repeating tests over a diseases treatment cycle for presence of improvement or decline.
