There is no clear superior modality. The Flutter combines oscillations (6\u201320 Hz) and positive expiratory pressure; the Lung Flute combines positive expiratory pressure and low frequency acoustic waves (18\u201322 Hz), to augment clearance. This project aimed to compare these devices.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>\n                      This was a randomized crossover study of adult subjects with stable non-cystic fibrosis bronchiectasis (expectorating &gt; 25 mL\/d). Subjects attended 2 separate out-patient visits, 1 week apart, and completed a supervised sputum clearance regime and Lickert scale (8 questions regarding subjects' perception of the experience using each device). Total sputum expectorated during supervised intervention (T1) and after 30 min from the end of T1 (T2) was recorded as wet sputum weight. Total wet sputum weight desiccated in a microwave (10 min at 300 watts), allowed measurement of total dry sputum weight.
