Acapella Versus Lung Flute in Treatment of COPD Patients the Study Aims to Identify the Preference Between the Two Devices According to Treatment of COPD Patients Regarding Pulmonary Function Tests , Exercise Tolerence and Quality of Life Questionnaire,

Chronic obstructive pulmonary disease (COPD) is a prevalent and progressive condition characterized by persistent airflow limitation and chronic respiratory symptoms. Among the many approaches to managing COPD, airway clearance techniques (ACTs) play a pivotal role in improving pulmonary function, reducing symptoms, and enhancing quality of life. So, this study aimed to investigate the comparative efficacy of two ACT devices-the Acapella® and the Lung Flute®- on improving pulmonary function, exercise capacity, and quality of life in COPD patients. The Acapella® and the Lung Flute®. Both devices utilize distinct mechanisms to facilitate mucus clearance and improve lung function. The Acapella® combines positive expiratory pressure (PEP) with oscillatory vibration, aiding in the loosening and mobilization of mucus . On the other hand, the Lung Flute® generates low-frequency sound waves through patient exhalation, stimulating mucus movement from the peripheral to central airways . While both devices have demonstrated efficacy in previous studies, there is limited comparative research evaluating their impact in COPD patients.
