Definition
Plethysmography is a test used to measure changes in blood flow or air volume in different parts of the body. It may be done to check for blood clots in the arms and legs, or to measure how much air you can hold in your lungs.
Penile pulse volume recording is a type of plethysmography done on the penis to check for causes of erectile dysfunction.
