What is the purpose of an incentive spirometer in post-operative care?

The purpose of an incentive spirometer in post-operative care is to encourage deep breathing and prevent pneumonia. After surgery, particularly abdominal or thoracic procedures, patients may have a reduced incentive to breathe deeply due to pain or discomfort. The use of an incentive spirometer provides a visual and interactive means for patients to practice deep breathing exercises.

By inhaling slowly and deeply, patients can expand their lungs, which helps to mobilize secretions, enhance oxygenation, and prevent atelectasis (the collapse of lung tissue). This deep breathing is crucial in preventing pneumonia, a common complication after surgery that can occur due to stagnant secretions in the lungs. Thus, the incentive spirometer serves as a valuable tool to promote respiratory health and recovery during the post-operative period.

Other options listed, like measuring lung capacity or monitoring blood oxygen levels, do not directly pertain to the main function of an incentive spirometer. While the device does relate to the respiratory system, its primary role is to facilitate deep breathing rather than serve as a measurement or medication delivery system.
