| plethysmograph | <physiology> An instrument for determining and registering the variations in the size or volume of a limb, as the arm or leg, and hence the variations in the amount of blood in the limb. Plethysmograph"ic. Origin: Gr. An enlargement + -graph. Source: Websters Dictionary (01 Mar 1998) |

| plethysmography | <physiology> The study, by means of the plethysmograph, of the variations in size of a limb, and hence of its blood supply. Source: Websters Dictionary (01 Mar 1998) |
| plethysmography, impedance | Recording changes in electrical impedance between electrodes placed on opposite sides of a part of the body, as a measure of volume changes in the path of the current. (12 Dec 1998) |
| plethysmography, whole body | Measurement of the volume of gas in the lungs, including that which is trapped in poorly communicating air spaces. It is of particular use in chronic obstructive pulmonary disease and emphysema. (12 Dec 1998) |
| pressure plethysmograph | A plethysmograph applied to part of the body, e.g., a limb segment, and arranged so that volume is measured during temporary application of sufficient pressure to the part to empty its blood vessels, a body plethysmograph in which changes of body volume are measured in terms of the consequent changes in air pressure in the body plethysmograph. Volume-displacement plethysmograph, a plethysmograph, usually a body plethysmograph, in which changes in volume displace a corresponding volume into or out of a very compliant measuring device, such as a Krogh spirometer or integrating flowmeter.
