Comparative Effects of ACBT and Diaphragmatic Breathing on Pulmonary Function and Sputum Diary After CABG

Comparative Effects of Active Cycle of Breathing Technique and Diaphragmatic Breathing on Pulmonary Function and Sputum Diary After Coronary Artery Bypass Graft

To compare the effects of active cycle of breathing technique and diaphragmatic breathing on pulmonary functions and sputum diary after coronary artery bypass graf

It will be a randomized clinical trial. Age of selected subjects will be between 40 to 60 years and data will be collected from intensive care units (ICUs) and cardiac care units (CCUs) of selected hospitals. There will be 2 groups i.e. group A will receive active cycle of breathing technique (ACBT) and group B will receive diaphragmatic breathing technique. Spirometer will be used to evaluate pulmonary functions and breathless, cough and sputum scale (BCSS) will be used to evaluate the improvement in sputum diary of patients. The trial will be completed in two days after patients admitted in the ICUs/CCUs and before and after each session, primary and secondary outcomes will be measured for both groups. After data collection, data will be analyzed using SPSS version 25
