Toe pressure
Toe Pressure
Toe pressure (pronunciation: /toʊ ˈprɛʃər/) is a medical term referring to the measurement of blood pressure in the arteries of the toes. It is often used in diagnosing and monitoring peripheral arterial disease (PAD).
Etymology
The term "toe pressure" is derived from the English words "toe", referring to the digit found at the end of a foot, and "pressure", which in this context refers to the force exerted by circulating blood upon the walls of blood vessels.
Procedure
Toe pressure is typically measured using a device called a photoplethysmograph, which uses infrared light to detect changes in blood volume in the small arteries of the toe. The patient's foot is first warmed to increase blood flow, then a small cuff is placed around the toe and inflated until blood flow is stopped. The cuff is then slowly deflated, and the pressure at which blood flow resumes is recorded as the toe pressure.
