Measurement is done with the patient lying flat, with feet at heart level, using sphygmomanometry: the big toe is slightly emptied of blood by squeezing, and a small cuff is inflated around the base of the toe. Cuff pressure is then slowly lowered until flow can be detected in the distal part of the toe, e.g. by optical means (photocell), by ...
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema, in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.
The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
The ABI is a simple, non-invasive test that measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm. This is based on the idea that if blood pressure readings in the ankle are lower than those in the arm, a blockage in the arteries that provide blood from the heart to the ankle is suspected. [ 55 ]
Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .

Korotkoff sounds are the sounds that medical personnel listen for when they are taking blood pressure using a non-invasive procedure. They are named after Nikolai Korotkov , a Russian physician who discovered them in 1905, [ 1 ] when he was working at the Imperial Medical Academy in St. Petersburg , the Russian Empire.
The height of AC component of the photoplethysmogram is proportional to the pulse pressure, the difference between the systolic and diastolic pressure in the arteries. As seen in the figure showing premature ventricular contractions (PVCs), the PPG pulse for the cardiac cycle with the PVC results in lower amplitude blood pressure and a PPG.
