Overview
Brief Summary
To compare the effects of conventional preoperative respiratory rehabilitation and specific preoperative respiratory rehabilitation program on pulmonary functions in coronary artery bypass graft patients.
Detailed Description
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.

Outcomes
Primary Outcomes
Ratio of Forced expiratory volume in 1 second and Forced Vital Capacity (FEV1/FVC)
Time Frame: 4th postoperative day of coronary artery bypass graft (CABG)
FEV1/FVC: The FEV1/FVC Ratio (FEV1%) parameter is calculated by dividing the measured FEV1 value by the measured FVC value. In healthy adults of the same gender, height, and age, the normal Predicted percentage should be between 70% and 85.
Forced expiratory volume in one second (FEV1)
Time Frame: 4th postoperative day of coronary artery bypass graft (CABG)
The Forced Expiratory Volume in 1 Second parameter measures the volume of air that was exhaled into the mouthpiece in the first second after a full inhalation. The normal test values range between 80% and 120% of the average (predicted) values.
Forced Vital Capacity (FVC)
Time Frame: 4th postoperative day of coronary artery bypass graft (CABG)
Forced Vital Capacity measures the total volume of air that you were able to blow forcefully into the mouthpiece following a full inhalation
Secondary Outcomes
- Borg scale(4th postoperative day of coronary artery bypass graft (CABG))
- 6-minute walk test (6MWT)(4th postoperative day of coronary artery bypass graft (CABG))
