the measurement of changes in the volume of organs or other body parts, particularly those changes resulting from blood flow.

plethysmography

A technique that detects changes in the volume of an organ, limb or the body, by measuring the flow of blood through its veins. See Arterial plethysmography, Impedance plethysmography, Ocular plethysmography.
Plethysmography
Whole body plethysmography measures the volume of gas in the lungs, including that which is trapped in poorly communicating air spaces,  of particular use in COPD and emphysema
Impedance plethysmography Venous impedance plethysmography A technique used to diagnose acute venous obstruction or vascular insufficiency of an extremity by measuring the change in limb volume with each arterial pulse and during cuff occlusion of the venous flow from the limb, the manipulation of which allows evaluation of either the arterial or venous flow

Penile plethysmography (PPG) is traditionally the most popular approach for assessing sexual arousal, and has been recommended for individuals with developmental disabilities (Caparulo, 1991; Haaven & Schlank, 2001; Nezu, Nezu, & Dudek, 1998; see also Card & Byrne, 1997; Lalumiere & Earls, 1992).
