Conditions

Bronchiectasis

Brief 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.

Interventions

OTHERFlutter 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.

OTHERexpiration 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.

OTHERControl

Patients were instructed to stay comfortably seated during 15 minutes. After this period they were stimulated to cough during a five minutes period.

Design outcomes

Primary

Measure	Time frame	Description
Dynamic and static lung volumes	In the week 1, 2 and 3. Before (baseline) and after each intervention.	Dynamic and static lung volumes were assessed by forced spirometry and plethysmography.

Secondary

Measure	Time frame	Description
Sputum production	Sputum was colected during the interventions	The expectorated secretions were collected using a sputum trap and quantificated by its dry weight.
