A Comparison of 2 Respiratory Devices for Sputum Clearance in Adults With Non-Cystic Fibrosis Bronchiectasis.

Background: Airway clearance techniques are a vital part of routine care for patients with bronchiectasis. There is no clear superior modality. The Flutter combines oscillations (6-20 Hz) and positive expiratory pressure; the Lung Flute combines positive expiratory pressure and low frequency acoustic waves (18-22 Hz), to augment clearance.
