Comparative Effects of Breather Device and Incentive Spirometer in Patients With COPD

Chronic obstructive pulmonary disease (COPD) is characterized and defined by limitation of expiratory airflow. This can result from several types of anatomical lesions, including loss of lung elastic recoil and fibrosis and narrowing of small airways. Inflammation, edema, and secretions also contribute variably to airflow limitation.it is a preventable and treatable disease characterized by persistent airflow limitation and respiratory symptoms, leading to cough, dyspnea, muscle weakness and fatigue affecting overall well-being and quality of life. The Breather is a respiratory muscle training device strengthening both inspiratory and expiratory muscles by breathing against a set resistance, which can be increased in line with training progress while. Another technique with proven effect in improvement of respiratory function and lung expansion is the incentive spirometry. incentive spirometry is used to encourage deep breathing and effective coughing, to achieve maximum dilation of the bronchi and prevent and treat pulmonary complications such as atelectasis in COPD patients.
