Subjects and methods: Thirty men patients with AECOPD were included in the study. Patients were assigned to a single group with pre- and post- treatment protocol application. All patients received high frequency chest wall oscillation with vest system in addition to their prescribed medication. The data concerned with the ventilatory functions included, forced vital capacity (FVC), forced expiratory volume in first second (FEV1), ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC), and Forced expiratory flow (FEF25-75 %.) were evaluated at the beginning of the study and after three weeks. Six minute walk test and (CAT) was also performed. Results: showed statistical significant difference for the ventilatory functions (FVC, FEV1, FEV1/FVC, and FEF25-75%.), also improvement in 6MWT and CAT between pre and post treatment in favor of post treatment condition. Conclusion: The current respiratory device (Vest Clearance HFCWO) provided an adequate physiotherapy method to patients with AECOPD, helped sputum expectoration, contributes in stabilization and improvement of respiratory functions, enhance patients' compliance and independence ER -
