Effects of sectional breathing on cardio-pulmonary function in a patient with coexisting bronchial asthma and pre-hypertension: a single case report

Non-communicable diseases (NCDs), such as cardiovascular diseases, chronic respiratory conditions, diabetes, and cancer, remain leading causes of morbidity and mortality worldwide. Hypertension and bronchial asthma are prevalent conditions that significantly contribute to cardiovascular risk. While pharmacological treatments are commonly used, alternative therapies like sectional breathing have gained attention for their potential role in improving cardiopulmonary function. This study explores the effects of sectional breathing on a patient with coexisting bronchial asthma and pre-hypertension. This single-case study involved a patient diagnosed with bronchial asthma and pre-hypertension. The intervention consisted of a structured, sectional breathing program over a specified period. Cardiopulmonary parameters, including pulmonary function tests (PFT), blood pressure, and heart rate, were assessed before and after the intervention. Patient adherence, comfort, and any adverse effects were also monitored throughout the study duration. Post-intervention, pulmonary function parameters, such as forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR), significantly improved. Additionally, blood pressure decreased, suggesting a potential autonomic regulatory effect of sectional breathing. Subjectively, the patient reported enhanced respiratory ease and a decrease in dyspnea episodes, reinforcing the physiological benefits of the intervention. The findings indicate that sectional breathing may be a promising adjunctive therapy for individuals with coexisting bronchial asthma and pre-hypertension. The observed improvements in pulmonary function and blood pressure suggest a potential role for non-pharmacological interventions in managing cardiopulmonary conditions. Further research with larger sample sizes and controlled study designs is recommended to validate these findings and elucidate the underlying physiological mechanisms.
