Effectiveness of slow deep breathing therapy on lowering blood pressure in hypertensive patients: A case study

Introduction: Hypertension is a cerebral vascular disorder in the form of narrowing of cerebral blood vessels, resulting in reduced oxygen and nutrient supply to the brain. It is characterized by an increase in systolic blood pressure >140 mmHg and diastolic pressure >90 mmHg. Non-pharmacological management is needed to be applied in lowering blood pressure. Slow deep breathing therapy exercises are done by breathing long and deep breaths slowly can stimulate the secretion of endorphins neurotransmitters in the autonomic nervous system which has an effect on decreasing the work of sympathetic nerves, increasing the work of parasympathetic nerves whose effects can affect heart rate to be slow and also vasodilation occurs in blood vessels. Objective: To lower blood pressure in hypertensive patients by using slow deep breathing exercises. Methods: The method used in this study used a case study with pre and post intervention, patients were given slow deep breathing exercises by breathing in through the nose for 3 seconds until they felt that the stomach expanded then held their breath for 3 seconds, then exhaled slowly through the mouth for 6 seconds, and repeated all steps for 15 minutes. Results: Obtained results of a decrease in blood pressure in patients after being given slow deep breathing exercises. Conclusion: Slow deep breathing therapy exercises with appropriate methods and procedures can be an alternative to lower blood pressure in hypertensive patients
