Chronic obstructive pulmonary disease is one of the most common life threatening disease affecting population. It is a preventable and treatable lung disease. People with COPD must work harder to breathe, which can lead to shortness of breath and/or feeling tired. Autogenic drainage (AD) works by adapting your breathing and maximizing airflow within the airways to improve ventilation and clear sputum. Segmental breathing, also referred to as localized expansion breathing, is the exercise used to improve ventilation and oxygenation. This research of randomized controlled trial will check the combined effects of segmental breathing technique and autogenic drainage technique in chronic obstructive pulmonary disease by taking sample of 40 patients through non probability convenient sampling and randomly allocating them into two groups A and B out of which A will receive both autogenic drainage and segmental breathing technique, B will receive autogenic drainage only for upto the duration of 3 days per week(20-45 min) for upto 4 weeks.Pre and post training outcomes will be measured through pulse oximeter,spirometer and BCSS.The data will be analyzed through SPSS 25.
