Protocol of an Observational, Follow up, Single Arm Study for Knowing the Compliance of Patients Scheduled for Major Abdominal and Thoracic Surgeries Who Were Instructed to Perform Spirometry in a Single Specialty Centre

Peri-operative incentive spirometry (IS) helps in improving pulmonary function, facilitates sputum clearance and prevents unwanted postoperative pulmonary complications after major abdominal and thoracic surgery. In our hospital, all patients are instructed to practice IS before abdominal and thoracic surgeries so that they can perform it in the postoperative period effectively. However, many patients do not follow our advice. A few unfortunate patients land up with pulmonary complications as it becomes difficult to train them after surgery.
