Pre-operative Respiratory Rehabilitation in Coronary Artery Bypass Graft Patients

After cardiac surgeries many postoperative changes occur that lead to pulmonary complication such as respiratory changes, functional capacity of lungs and gaseous changes that leads to hypoxemia and ischemic injury of lungs. CABG, although a successful procedure, post operative pulmonary complications still pursue a big challenge to the health and fitness of the patients. Although post operative complications have been managed in in-patient setup post CABG, there are pre-operative measures on the rise to prevent the complications to occur after CABG.

This study will contribute in describing the rate of improvement in pulmonary functions with rehabilitation program including preoperative out of bed mobilization, active cycle breathing techniques, forced expiratory technique and volume-based incentive spirometry as compared to the conventional treatment of flow-based incentive spirometry and chest percussion in prevention of post operative pulmonary complications occurring after CABG leading to delayed recovery of patients.
