Comparative Effect of Pursed Lip Breathing Alone and Combined With Alternate Nostril Breathing on Pulmonary Function Test and Quality of Life in Patients in Grade I COPD Patients.

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory condition characterized by persistent airflow limitation, chronic inflammation of the airways, and reduced lung function. It is commonly associated with long term exposure to harmful particles or gases, especially cigarette smoke. Patients with COPD often experience symptoms such as breathlessness, chronic cough, sputum production, and reduced exercise tolerance, which significantly affect their daily activities and overall quality of life. Pulmonary rehabilitation, particularly breathing exercises, plays an important role in the physiotherapy management of COPD.

Among the commonly used breathing techniques, pursed lip breathing is widely recommended for patients with COPD. This technique helps slow down expiration, prevents airway collapse, reduces air trapping, and improves ventilation efficiency. As a result, it may decrease dyspnea and enhance oxygen exchange. Another breathing technique, alternate nostril breathing, is a yogic breathing exercise that promotes better control of respiration, improves relaxation, and may enhance respiratory muscle coordination.

The purpose of this study is to investigate the effect of pursed lip breathing alone and in combination with alternate nostril breathing on patients with Grade I COPD. The study aims to determine whether the combined use of these breathing techniques can provide additional benefits compared to pursed lip breathing alone. By improving breathing patterns and respiratory mechanics, these interventions may help patients manage symptoms more effectively and enhance their functional capacity.

This research will follow an interventional study design in which participants will be divided into two groups. One group will receive pursed lip breathing exercises, while the second group will perform both pursed lip breathing and alternate nostril breathing. The intervention will be conducted over a specified period under proper supervision and guidance.

The findings of this study may contribute to the development of more effective physiotherapy based breathing exercise programs for patients with mild COPD and may support the integration of combined breathing techniques in pulmonary rehabilitation programs.
