Clinical Trial Summary

This study aimed to evaluate the acute physiological effects of expiration with the glottis open in lateral posture (ELTGOL) and Flutter valve in dynamic and static lung volumes in patients with bronchiectasis and, secondarily, to study the effect of these techniques in sputum production.

Intervention

Other:
• Flutter valve
Flutter valve is a physiotherapy device commonly used for the treatment of pulmonary hypersecretive conditions. The patients is taught to exhale through the device, producing positive expiratory pressure and flow oscillations. In this study the intervention took 15 minutes. During this period the patients were free to cough.
• expiration with the glottis open in lateral posture (ELTGOL)
This technique is a maneuver of slow expiration with the glottis open, with the subject in lateral posture. The patients performed three sets of 10 repetitions in left and right lateral decubitus.
• Control
Patients were instructed to stay comfortably seated during 15 minutes. After this period they were stimulated to cough during a five minutes period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dynamic and static lung volumes	Dynamic and static lung volumes were assessed by forced spirometry and plethysmography.	In the week 1, 2 and 3. Before (baseline) and after each intervention.	No
Secondary	Sputum production	The expectorated secretions were collected using a sputum trap and quantificated by its dry weight.	Sputum was colected during the interventions	No
