Impact of Slow Deep Breathing Exercises using Incentive Spirometry on Functional Capacity among Patients with Coronary Artery Disease

Introduction A condition known as coronary artery disease occurs when the myocardium does not receive enough blood or oxygen. It is caused by blockage of the coronary arteries and is characterized by an imbalance in the supply and demand of oxygen. Usually, it involves blood flow obstruction caused by plaques that form in the coronary artery lumen. It is the leading global cause of death. Methods Participants in this quasi-experimental research design included patients with coronary artery diseases. Patients with severe respiratory conditions, a history of coughing, difficulty breathing deeply, non-pulmonary status at first examination, and inability to complete the study were among the exclusion criteria. the participants in the study were 50 samples (25 research groups and 25 control groups), the research groups were given an incentive spirometer in addition to hands-on instruction on how to use it and collect accurate measurements. Patients were told to lie down or sit in order to breathe in and out through the tube 10 times. Patients were instructed to do this exercise three times every eight hours for a duration of three weeks. Findings: Three weeks following the intervention, a re-assessment of the functional capacity, revealed an improvement in factional capacity solely in the study groups relative to the pre-test. Conclusion Using an innovative spirometer, the study demonstrated the impact of various deep breaths on the functional capacity of patients with CAD. Nearly all patients demonstrated a significant short-term improvement in their functional capacity, and no significant side effects were found. Consequently, this methodology can be applied in subsequent research to examine long-term impacts for weeks or months. Because it is simple to use and the measurement is non-intrusive, this method is perfect for self-monitoring at home.
