spirometer

 [spi-rom´ĕ-ter]
an instrument for measuring air inhaled into and exhaled out of the lungs; it provides a simple way of determining most of the lung volumes and capacities that are measured in pulmonary function tests. One type is the water-seal spirometer, which consists of a hollow drum floating over a chamber of water and counterbalanced by weights so that it can move freely up and down. Inside the drum is a mixture of gases, usually oxygen and air. Leading from the hollow space in the drum to the outside is a tube that has a mouthpiece through which the patient breathes. As one inhales and exhales through the tube the drum rises and falls, causing a needle to move on a nearby rotating chart. The tracing recorded on the chart is called a spirogram.
Using a flow spirometer. From Lammon et al., 1995.

spi·rom·e·ter

(spī-rom'ĕ-tĕr),
In clinical practice and research, any device used for measuring flows and volumes, inspired and expired by the lungs, thus assessing pulmonary function. Considered the most basic measurement device of pulmonary function.
[L. spiro, to breathe, + G. metron, measure]

spirometer

[spīrom′ətər]
Etymology: Gk, speira + metron, measure
an instrument that measures and records the volume of inhaled and exhaled air, used to assess pulmonary function. Volumetric information is recorded on a chart, called a spirogram. spirometric, adj.
