An instrument that measures variations in the size of an organ or body part on the basis of the amount of blood passing through or present in the part.

The test involves sitting in an airtight booth and blowing into a mouthpiece while a computer records measurements. Body plethysmography is a well-established technique of lung function determination. Its frequency of clinical use appears to differ between countries, with the most intensive application in the German-speaking countries. Plethysmography is a noninvasive diagnostic manometric study used to measure changes in the size of blood vessels by determining volume changes in the blood vessels of the eye, extremities, and neck or to measure gas volume changes in the lungs. While photoplethysmography commonly requires some form of contact with the human skin (e.g., ear, finger), remote photoplethysmography allows to determine physiological processes such as blood flow without skin contact. When airway obstruction is present this will mean that you can’t blow your air out as fast as you should be able to.

A plethysmograph is an instrument for measuring changes in volume within an organ or whole body (usually resulting from fluctuations in the amount of blood or air it contains). The word is derived from the Greek "plethysmos" (increasing, enlarging, becoming full), and "graphein" (to write).

The average total lung capacity of an adult human male is about 6 litres of air. Lung volumes measurement is an integral part of pulmonary function test.

Air plethysmography uses a similar principle but based on an air-filled long cuff, which is more convenient but less accurate.
