Physiological Effects of Expiration With the Glottis Open in Lateral Posture (ELTGOL) and Flutter Valve in Patients With Bronchiectasis

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.

Treatment and study plan

Flutter valve

Other

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)

Other

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

Other

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

Primary outcomes

  1. Dynamic and static lung volumes

    Time frame: 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 outcomes

  1. Sputum production

    Time frame: Sputum was colected during the interventions

    The expectorated secretions were collected using a sputum trap and quantificated by its dry weight.
