Evaluation of Oscillatory Positive Expiratory Pressure (oPEP) in Bronchiectasis and COPD

"The oPEP system (Aerobika ®) combines positive expiratory pressure therapy and airway vibrations to help mobilize pulmonary secretions. oPEP therapy (Aerobika ®) enforces a resistance to exhalation at the mouth, while the airway vibration technology transmits movements upstream during exhalation so that airway walls may become free from mucous. Subjects will take home the device and use four times daily during the active part of the study.~There is only one intervention for this study. Subjects are on treatment for three weeks and off for the alternate three weeks."
