Effects of Alternate Nostril Breathing and Bellows Breath in COPD Patients

COPD is a common respiratory disease characterized by progressive airflow obstruction, dyspnea, chronic cough, and sputum production. Alternate nostril breathing and bellows breath are pranayama-based breathing techniques that may improve respiratory function and overall well-being. This randomized clinical trial aims to compare the effects of these techniques on sputum clearance, pulmonary function tests, and quality of life in COPD patients. The study will be conducted at Punjab Institute of Cardiology using convenient sampling. Participants will be divided into two groups: Group A will perform alternate nostril breathing, while Group B will perform bellows breath exercises for 15-20 minutes daily over 3-4 weeks. Outcome measures include sputum clearance, spirometry, and quality of life questionnaires. Data will be analyzed using SPSS with significance set at p \< 0.05. The study may support the use of cost-effective, noninvasive breathing techniques for improving pulmonary function and quality of life in COPD patients.
