Actual aim of“this review article is to study and to make a report an overview on the efj“ects of“ breathing exercises and incentive spirometry in improving lung capacity on individuals with lung fibrosis. Incentive spirometer is a device that ofj“ers patients with visual and other positive response. Incentive Spirometry is exercises that have been used to enhance lung expansion. Incentive Spirometry is essential to the thoracotomy patients by increasing inspiratory capacity and improves inspiratory muscle strength in patients. The risk and severity of“ complications can be reduced by the use of“ therapeutic maneuvers that increase lung volume. Incentive spirometry has been routinely considered a part of“ the perioperative respiratory therapy strategies to prevent or treat complications. Incentive spirometry is designed to mimic natural sighing or yawning by encouraging the patient to take long, slow, deep breaths. People living with chronic lung diseases, such as chronic obstructive pulmonary disease (C’OPD), C’OVID 19, emphysema and pulmonary fibrosis, experience similar lung disease symptoms. Shortness of“breath and decreased lung function make breathing difficult. Sometimes, doctors recommend their patients use an incentive spirometer. Incentive spirometers are prescribed af“ter surgery or as part of“a lung disease treatment plan. Here are the f“acts you need to know about incentive spirometry benefits.
