Abstract

Objectives: The purpose of the study was to compare the volume and flow incentive spirometer on PEFR, SpO 2 , chest expansion, and QOL in patients undergoing CABG surgery. Patients and methods: This experimental study was performed with 50 patients (8 females, 42 males between the age group of 40-75 years). The patients were equally divided into two groups: Group 1: volume incentive spirometer along with conventional therapy (ACBT and deep breathing exercise) and Group 2: flow incentive spirometer along with conventional therapy (ACBT and deep breathing exercise). Evaluations were done at baseline, post-OP 2 nd day, post-OP 7 th day and 1 month follow up of QOL. PEFR, SpO 2 , chest expansion, and QOL were assessed. Results: No statistically significant difference observed in demographic details of patients at baseline in terms of age, BMI, and smoking history while in the case of gender, there was a significant difference observed (p=0.00*). Within group were analyzed by using repeated measures of ANOVA, the p-value at the level of p<0.001 was found to be statistically highly significant (p=0.000**) in both group at baseline, post-OP 2 nd day and post-OP 7 th day. Between groups were analyzed by using independent t-test and found that there was a highly significant difference observed in PEFR, SpO 2, and chest expansion between both groups at post-OP 7 th day (p≤0.05). Similarly, QOL also showed a highly significant level after 1-month follow-up (p≤0.05).
