Oscillating Positive Expiratory Pressure Devices and Acute Exacerbation of Chronic Obstructive Pulmonary Disease

Summary

Sputum production increases in acute exacerbation of COPD, both in amount and consistency. It increases airways obstruction and hence delays improvement and prolongs hospital stay. oscillating positive expiratory pressure (OPEP) devices were extensively studied in cystic fibrosis and bronchiectasis. Only seldom studied in chronic bronchitis. This study aims to measure the effects of mucous clearing device in hospitalized patients with acute exacerbation of COPD.
