Blend Of Semifowler’s Position With Chair Sitting In Optimizing The PFT, PEFR And RPE Scale Post Operative Coronary Artery Bypass Graft Surgery: A Randomized Controlled Trial

Abstract

BACKGROUND: Coronary Artery Disease (CAD), characterized by inflammation and atherosclerosis, often necessitates the Coronary Artery Bypass Graft (CABG) procedure, especially for multi-vessel disease, reducing mortality and symptoms. Peak expiratory flow rate, pulmonary function test assess lung function; dyspnoea and RPE gauge breathing discomfort and exertion perception. Body position crucially affects pulmonary function.

OBJECTIVES: The purpose of the study was to find out the impact of body positions on PFT, PEFR and dyspnoea in patients with post op CABG.

METHODOLOGY:  Study Design- Experimental study design, study type: A Randomized control trial, subjects were selected based on inclusion and exclusion criteria with simple random sampling technique. Subjects with post op CABG were taken. PFFR, PFT and RPE scale were used to assess pre and post effect of semi fowlers position blending with chair sitting position.

RESULT: Student t-test analysis was used to examine the outcome. The analysis that met statistical significance was (p<0.001). The mean PEFR of the post-experimental group (309.52) is greater than that of the post-control group (223.81). While the post-experimental group's mean FVC (2.91) and FEV1 (2.45) is greater than the post-control group's mean FVC (2.11) and FEV1 (1.87), the post-experimental group's mean RPE is 7.81 points lower than the post-control group's (11.2). The mean FEV1/FVC of the post-experimental group (0.97) is greater than that of the post-control group (0.85).

CONCLUSION: The study concluded that improvement in PEFR, PFT and RPE scale values is seen after implementing blend of semi fowlers position with chair sitting position in post op CABG patients.
