2-17. INCENTIVE SPIROMETRY
a. An incentive spirometer is a device that stimulates the patient to achieve maximum voluntary lung expansion. The purpose of the device is to help the patient achieve deeper inspirations.
b. In performing the exercise, the patient places his lips securely over the mouthpiece of the spirometer and inhales as deeply as possible. At maximum inflation there should be a slight pause, and the patient then relaxes and exhales.
c. The spirometer is normally equipped with a visual reinforcement device for patient encouragement. For example, a light may come on at maximum inspiration or the patient may watch a plastic ball rise to the top of a chamber during inspiration.
d. The patient should be encouraged to cough and expectorate any secretions loosened by the deep breathing.
