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.
