Introduction: Chronic Obstructive pulmonary disease (COPD) is characterized by airflow obstruction with breathing-related symptoms such as chronic cough, exertion dyspnoea, expectoration, and wheeze [1]. The Buteyko concept is a system of breathing exercises originally devised in the 1950s by Professor Konstantin Buteyko, a Russian physician and academic personality [2]. Aim of The Study: To compare the better Effectiveness of Buteyko Breathing Technique and Pursed Lip Breathing in Chronic Obstructive Pulmonary Disease. Methodology: Fifty (50) subjects clinically diagnosed of chronic obstructive pulmonary disease (COPD). The subjects divided randomly into two groups; Group A (25) and Group B (25). Group A receivedButeyko Berthing Technique (BBT) and Group B received Pursed Lip Breathing (PLB) and done for 4 weeks. Discussion: The Buteyko method is a purported method of "retraining" the body's breathing pattern to correct for the presumed chronic hyperventilation and hypocapnea, and thereby treat or cure the body of these medical problems. Buteyko has been found to be effective in management of Asthma [10]. In our study daily Buteyko breathing exercise session of 30 to 35 minutes was given to patients. Progression of the exercise was made as per the exercise manual of Buteyko Institute of Breathing & Health. Conclusion: In the present study both of the techniques are effective but the Buteyko breathing technique found more effective than pursed lip breathingfor 4 weeks. There was significant improvement in Pulmonary Function Test in patients with COPD.
