 The objective of this study is to evaluate the safety and efficacy of four times daily Positive Expiratory Pressure maneuvers over three weeks in individuals with bronchiectasis and COPD with chronic sputum production. The oPEP device Aerobika combines positive expiratory pressure therapy and airway vibrations to help mobilize pulmonary secretions. oPEP therapy 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 mucus. An adjustable dial allows users to adjust the frequency and the flow resistance based on their individual needs. Subjects will take a device home and use four times daily during the active part of the study. We hypothesize that daily oPEP use will significantly improve dyspnea, movement of mucus, SGRQ score, and 6MWD after three weeks of four times daily administration.
