Incentive spirometer is indicated for patients who have had any surgery that might jeopardize respiratory function, particularly
surgery to the lungs, but also to patients recovering from
cardiac or other surgery involving extended time under
anesthesia and prolonged in-bed recovery. Under general anesthesia and inactivity, a patient's breathing may slow, causing air sacs in their lungs to not fully inflate.
Atelectasis can develop and, if unmanaged, lead to
pneumonia and
postoperative fever. Pneumonia is a major lung complication associated with increased morbidity and mortality, length of hospital stay, and likelihood of hospital readmissions. In conjunction with breathing exercises and early mobility, incentive spirometry use is therefore beneficial for patients recovering from pneumonia or rib damage to help minimize the chance of fluid build-up in the lungs. Because of its role in pulmonary rehabilitation and inspiratory muscle training, this device may theoretically benefit patients with
COVID-19. It may be used as well by wind instrument players who want to improve their air flow. ==Indications==
