Incentive spirometry reduces the risk of atelectasis and pulmonary consolidation. 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.
