Effect of Active Cycle of Breathing Technique as Add on to Routine Chest Physical Therapy on Respiratory Parameters in Coronary Artery Bypass Graft Patients

A controlled trial was conducted to determine the effect of the active cycle of breathing technique (ACBT) in improving respiratory parameters after coronary artery bypass graft surgery. The main aim of this study was to determine the effects of pre and postoperative active cycle of breathing technique (ACBT) in coronary artery disease patients undergoing coronary artery bypass graft surgery in improving respiratory parameters such as arterial blood gas (ABG), oxygen saturation (SpO2) and respiratory rate. The intervention group performed an active cycle of breathing technique with routine chest physical therapy while the control group performed routine chest physical therapy. Arterial blood gas (ABG), oxygen saturation (SpO2), and respiratory rate were measured at baseline and five days after surgery, every 2 hours on postoperative days 1, 2, and 3 and 4 hours on days 4 and 5. Participants in the intervention group performed preoperative routine chest physical therapy sessions were followed as: * Incentive spirometry, 3 sessions per day, 10 repetitions * Percussions, 3 sessions per day, 20 repetitions * 3-minutes walking, 2 sessions per day * ACBT, 3 sessions per day The preoperative chest physiotherapy treatment plan was continued after CABG surgery. In addition to these, the following were included postoperatively: * Nebulization, 3 sessions per day * 3 minutes of walking, 2 sessions per day * ACBT, 3 sessions per day While participants in the control group performed the same pre and postoperative sessions except ACBT.
