effects of segmental breathing exercise in patients awaiting coronary artery bypass graft surgery (cabg)

Conditions: Complications Due to Coronary Artery Bypass Graft

Summary: to determine the effects of preoperative segmental breathing exercise on postoperative pulmonary complications in patients awaiting coronary artery bypass graft surgery (cabg). this study will be a randomized controlled trial. this study will be conducted in cardiac surgery department at faisalabad institute of cardiology. sample size will be 44including both male and female. non- probability purposive sampling technique will be used. modified healthy heart questionnaire will be used as a screening tool. baseline, postoperatively before discharge at week 5 assessment will be done by 6-minute walk test. subjects in group a (interventional group) will be treated using segmental breathing exercises combined with conventional treatment (deep breathing exercise ) and the group b (control group) will be treated with only conventional treatment. group-a (interventional group) will receive segmental breathing exercises for one month 5 days a week and 2 sessions per day for 15 minutes for each patient. conventional treatment will be for one month 5 days a week 10 to 15 repetitions of deep breathing exercise 2times a day. dyspnea will be checked baselineand at week5 by modified borg scale.sputum cup was used for expectoration of sputum . quality of life will be checked baseline and at week 5by sf-12 questionnaire. outcome variables will be 6mwt, dyspnea, quality of life, oxygen saturation, heart rate, blood pressure and expectoration of sputum. data will be analyzed on spss-25.
