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

Study Overview
=================
Brief Summary
-----------------
To compare the effects of active cycle of breathing technique and diaphragmatic breathing on pulmonary functions and sputum diary after coronary artery bypass graf

Detailed Description
-----------------
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

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6 Min walk test | The 6 min walk test is a sub-maximal exercise test used to assess aerobic capacity and endurance.It is also use to monitor your response to treatments for heart lung and other health problems. Provides a measure for integrated global response of multiple cardiopulmonary and musculoskeletal systems involved in exercise. | 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Borg Rating of Perceived scale | Is a way of measuring physical activity intensity level.It has a range from 6 to 20 ,scale correlates with a person heart rate or how hard they feel they are working.Ask you to rate the difficulty of your breathing. | 4 weeks |
