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.

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.

spirometer
an instrument for measuring air taken into and expelled from the lungs. The spirometer provides a relatively simple method for determining most of the lung volumes and capacities that are measured in pulmonary function tests.

With substantial practice, however, children and adolescents with Down syndrome are able to achieve reproducible and valid results on spirometric testing (Dichter et al 1993).
Specifically the clinician notes the following information when determining the classification of asthma severity: how often the patient experiences symptoms of asthma each day, how frequently the patient awakens during the night because of asthma symptoms, how often the patient requires the use of a short-acting beta-two agonist to control asthma symptoms, the degree to which symptoms of asthma interfere with the patient's activity level, and spirometric data, specifically the FEV1.
