incentive spirometry


spirometry

 [spi-rom´ĕ-tre] measurement of the breathing capacity by means of a spirometer; results can record capacity" >total lung capacity, vital capacity, volume" >tidal volume, capacity" >functional residual capacity, and volume" >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.

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. See: illustrationSee also: spirometry
