spirometry

 [spi-rom´ĕ-tre]
measurement of the breathing capacity by means of a spirometer; results can record total lung capacity, vital capacity, tidal volume, functional residual capacity, and residual volume.
incentive spirometry a goal-oriented inhalation maneuver in which the patient is encouraged by visual feedback from a spirometer to execute sustained maximal inhalation. Patients usually perform 10 to 20 sustained deep breath exercises an hour until they can achieve their predicted inspiratory reserve volume. See illustration.
Spirometry, showing respiratory volumes and capacities as subdivisions of total lung capacity. From Applegate, 2000.

spi·rom·e·try

(spī-rom'ĕ-trē),
Making pulmonary measurements with a spirometer.

spirometry

/spi·rom·e·try/ (spi-rom´ĕ-tre) the measurement of the breathing capacity of the lungs, such as in pulmonary function tests. See also spirography. spiromet´ric

spirometry

[spīrom′ətrē]
laboratory evaluation of the air capacity of the lungs by means of a spirometer. Compare blood gas determination. spirometric, adj.

spirometry

The measurement of the movement of air in and out of the lungs during various breathing maneuvers, which is the most important pulmonary function test. See Incentive spirometry, Pulmonary function test.

INCENTIVE SPIROMETER

incentive spirometry

Spirometry in which visual and vocal stimuli are given to the patient to produce maximum effort during deep breathing. Incentive spirometry is used most often in postoperative patients to prevent atelectasis.

spirometry

A lung function test used to determine the efficiency with which air passes from the atmosphere to the ALVEOLI of the lungs and carbon dioxide passes out. Spirometry can also be used to assess the maximum volume of air that can be made to pass in and out of the lungs (the vital capacity).

Spirometry

A test using an instrument called a spirometer that shows how difficult it is for an asthmatic patient to breathe. Used to determine the severity of asthma and to see how well it is responding to treatment.
