Additional Effects of Flutter With Conventional Chest Physiotherapy on Peak Expiratory Flow Rate and Chest Expansion in Post CABG Patients With COPD
Sponsor: Foundation University Islamabad
Summary
Flutter therapy is an oscillating positive expiratory pressure (OPEP) technique that combines positive expiratory pressure with airway oscillations to facilitate mobilization and clearance of respiratory secretions. Conventional chest physiotherapy includes deep breathing exercises, incentive spirometry, airway-clearance techniques, splinted coughing and early mobilization to promote lung expansion and secretion clearance. A total of 94 patients aged 40-70 years with mild-to-moderate COPD undergoing elective coronary artery bypass grafting (CABG) will be enrolled in this randomized controlled trial and will be randomly allocated into two groups, with 47 participants in each group. The intervention group will receive conventional chest physiotherapy combined with Flutter therapy, while the control group will receive conventional chest physiotherapy alone. Both groups will receive supervised treatment for 5 consecutive postoperative days, with 3 sessions per day, resulting in 15 treatment sessions. Baseline assessment will be performed on postoperative day 1 before commencement of the intervention, and post-intervention assessment will be conducted on postoperative day 5. The study will compare the effects of Flutter-assisted conventional chest physiotherapy versus conventional chest physiotherapy alone on postoperative peak expiratory flow rate, chest expansion and airway clearance.

Interventions
Conventional Chest Physiotherapy
1. Diaphragmatic Breathing Description: Slow deep breathing emphasizing diaphragmatic movement performed for10 repetitions × 3 sets per session. 2. Incentive Spirometry Description: Sustained maximal inspiration using an incentive spirometer 10 repetitions × 3 sets per session. 3. Chest Percussion Description: Rhythmic clapping of the chest wall with a cupped, 02-03 minutes on Day 1, 03-05 minutes on Days 2-5. 4. Splinted Coughing Description: Controlled coughing with support to the surgical incision using a pillow or hands to facilitate secretion clearance while minimizing discomfort as needed/occasional during the session. 5. Early Mobilization Description: Gradual progression of physical activity during the postoperative period, including sitting, standing and ambulation, as tolerated. A 05-day protocol will be followed.
Flutter device with conventional chest physiotherapy
Flutter therapy will be administered as an adjunct to conventional chest physiotherapy using a portable, oscillating positive expiratory pressure (OPEP) device, for 3 sessions per day for 5 consecutive postoperative days.
