plethysmograph

 [plĕ-thiz´mo-graf]
any device for measuring and recording variations in the volume of an organ, part, or limb.
body plethysmograph a device used in pulmonary function tests to measure parameters such as functional residual capacity (FRC) and lung-thorax compliance (CLT). It consists of a large box in which the subject can be sealed so that volume of the thorax can be determined from pressure changes in the box.

bod·y ple·thys·mo·graph

a chamber apparatus surrounding the entire body, commonly used in studies of respiratory function.

body plethysmograph

Etymology: AS, bodig + Gk, plethynein, to increase, graphein, to record
a device for studying alveolar pressures, lung volumes, and airway resistance. The patient sits or reclines in an airtight compartment and breathes normally. The pressure changes in the alveoli are reciprocated in the compartment and are recorded automatically.

body plethysmograph
a device used in pulmonary function tests to measure parameters such as functional residual capacity (FRC) and lung-thorax compliance (CLT). It consists of a large box in which the subject can be sealed so that volume of the thorax can be determined from pressure changes in the box while the lung volume and gas pressure in the lungs are measured by spirometry.

Body plethysmographs can register gas compression volume during the flow-volume manoeuvre with no extra effort by the user, and the investigation of the possible changes in gas compression after administration of a bronchodilator may be valuable in assessing the effect of bronchodilators.
