An incentive spirometer is a device specifically designed to encourage patients to take deep breaths by inhaling slowly and deeply to improve lung function. The primary measurement that an incentive spirometer provides is vital capacity, which is the maximum amount of air a person can expel from their lungs after a maximum inhalation. This measurement is crucial for assessing lung function, especially postoperatively or in patients with pulmonary conditions, as it helps evaluate the effectiveness of lung inflation and aids in preventing complications such as atelectasis.

By using the incentive spirometer, patients can visualize their lung capacity and track improvements over time, making it a valuable tool in respiratory rehabilitation. The goal of using an incentive spirometer is to help maximize lung expansion and ensure that the alveoli—the small air sacs in the lungs—are adequately ventilated and oxygenated, promoting better overall respiratory health.
