Plethysmography

Definition

Plethysmography is used to measure changes in volume in different parts of the body. The test may be done to check for blood clots in the arms and legs. It is also done to measure how much air you can hold in your lungs.

Penile pulse volume recording is a type of this test. It is done on the penis to check for causes of erectile dysfunction.

Most commonly, this test is performed to check blood flow in the arteries of the legs. This is done in people with conditions like hardening of the arteries (atherosclerosis). Atherosclerosis causes pain during exercise or poor healing of leg wounds.
