Effect of Slow Deep Breathing Exercises by Using Incentive Spirometry on Cardio-pulmonary Parameters, Electrocardiographic Findings and Functional Capacity among Patients with Coronary Artery Disease

Abstract

A condition known as coronary artery disease occurs when the myocardium does not receive enough blood or oxygen caused by plaques that is formed in the coronary artery lumen. That supplies the heart with blood, a muscle that needs aerobic exercise to generate enough Adenosine Triphosphate to keep contracting. It is brought on by coronary artery blockage and is distinguished by an imbalance in the supply and demand of oxygen. The study aimed to investigate the impact of slow, deep breathing exercises using incentivized spirometry on cardio-pulmonary parameters, electrocardiographic findings, and functional ability in coronary artery disease patients. The study involved fifty participants, divided into two groups: control and study. To assess the impact of slow deep breathing exercises incentive spirometry was used instrument, which includes four parts. Each part has many items. The instrument’s validity was obtained by a 10-person pundit panel, while the instrument’s dependability was assessed using a test-and-retest approach. Data analysis was performed using inferential and descriptive statistics. Three weeks after the intervention, re-test of functional capacity investigated between two groups. The result of study shows significant in the functional capacity with self-care ability, family and social ability, movement ability, lifting ability, work ability, physical functional ability, with p-value= (.000). The study concluded that flow-oriented incentive spirometry was beneficial in improving functional capacity compared between control and the study groups, with no significant side effects. This methodology can be applied in future research to examine long-term impacts over weeks or months and is suitable for self-monitoring at home due to its simplicity and non-intrusive nature.
