A Comparative Study on the Effects of Incentive Spirometry and Deep Breathing Exercise on Pulmonary Functions after Uncomplicated Coronary Artery Bypass Grafting Surgery
Subscribe/Renew Journal
Purpose
Compare the effects of Incentive spirometry and deep breathing exercise on pulmonary functions after uncomplicated coronary artery bypass surgery.
Methods
Thirty two patients for elective coronary artery bypass surgery with age group of 38-68 years were included for the study. They were trained preoperatively and randomly assigned to two groups and performed either incentive spirometry or deep breathing exercises according to the group they assigned.
Measurements
Pulmonary function test variables including; FEV1, FVC, and FEV1/FVC were measured preoperatively and third postoperative day. Arterial Blood Gas analysis for PaO2, PaCO2 were done on first three postoperative days before and after the breathing exercises.
Results
Independent paired test was performed to compare between the groups, and paired test was used to compare all variables within each group. Significant differences were found in PaO2 and PaCO2 in all three postoperative days after breathing exercises. There was no significant difference between the groups.
Conclusion
The results of this study suggest that, deep breathing exercises and incentive spirometry are of equal effect, provided the patients do not have any complication after coronary artery bypass surgery.
