plethysmograph [plĕ-thiz´mo-graf]
ple·thys·mo·graph (pl -th z m -gr f )n. 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. ple·thys mo·graphic adj. |
plethysmograph
[pləthiz′məgraf′]
an instrument for measuring and recording changes in the size and volume of extremities and organs by measuring changes in their blood volume. plethysmographic, adj.
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.
