What is the purpose of an incentive spirometer?

The purpose of an incentive spirometer is to encourage deep breathing. This device is primarily used to help patients take deep breaths, which can enhance lung function and promote the expansion of the alveoli (the tiny air sacs in the lungs). Deep breathing is essential, especially after surgery or during recovery from respiratory illnesses, as it helps prevent complications such as pneumonia and atelectasis (lung collapse).

By using the incentive spirometer, patients are motivated to inhale deeply, which increases the amount of air in the lungs and can aid in clearing mucus. It also provides visual feedback through a measurable scale, motivating patients to achieve specific breathing goals, thereby improving their overall pulmonary function and promoting respiratory health.
