Effectiveness of Pursed Lip Breathing Exercise on Selected Physiological Parameters among COPD Patients

Most of the respiratory problems are chronic in nature associated with advancing age and accompanied by breathing difficulty and poor quality of life. Respiratory exercise practice facilitate for structural and physiological adaptations thus enhances survival and daily performance. The present study examines the effectiveness of pursed lip breathing exercise on physiological parameters such as respiratory rate, heart rate and peak expiratory flow rate among COPD patients residing in communities of Udupi district, Karnataka. Patients were evaluated before and after pulse lip breathing exercise using physiological parameters assessment scale. Statistical calculations were done using paired t-test and Chi-square test. The study drew the conclusion that pursed lip breathing exercise is effective in normalizing the physiological parameters such as respiratory rate, heart rate and peak expiratory flow rate among COPD patients.
