Progressive Muscle Relaxation (PMR) Enhances Oxygen Saturation in Patients of Coronary Heart Disease

Abstract

Coronary Heart Disease (CHD) is a disorder of heart function due to heart muscle lacking blood due to the narrowing of coronary arteries. Attack of coronary heart disease will result in decreased blood supply to the heart muscle, so that blood pumped throughout the body will decrease. This can be indicated by the value of decreased oxygen saturation. The purpose of this study was to determine the effect of progressive muscle relaxation on oxygen saturation in coronary heart disease in General Hospital Ciamis Indonesia. This research is quantitative by using a research quasi-experimental design. The design used was a pre-test and post-test without a control group. The Technique sampling used in this study was consecutive, as many as 30 people. Analysis of data using univariate and bivariate analysis, dependent t-test (paired t-test) to test differences in oxygen saturation values before and after the intervention. Statistical test results obtained p-value 0,000 (p <0.05), it can be concluded that there is an increase in the value of oxygen saturation after progressive muscle training.
