Summary

ELTGOL (Slow Expiration with the Opened Glottis in the Lateral posture) is an airway clearance technique performed in the lateral decubitus position. This technique focuses on optimizing ventilation of the infralateral lung (when the subject is lying in the lateral posture) to enhance local air-liquid interaction. Previous studies on ventilation differences between the infra- and supralateral lungs were conducted on healthy, young, male subjects, without the application of thoracic or abdominal pressure.

This study aimed to assess ventilation distribution in right lateral recumbency in patients with chronic obstructive pulmonary disease (COPD), as well as healthy individuals, and investigate the impact of thoracic and abdominal manual pressures during ELTGOL on ventilation distribution.

Conditions

Interventions

BEHAVIORAL

ELTGOL_Physio

The subject will be asked to slowly exhale with the glottis opened in the right lateral posture. The physiotherapist will accompany the subject by gently applying manual pressure on the chest wall and the abdomen during expiratory phases.

BEHAVIORAL

ELTGOL_Auto

The subject will be asked to slowly exhale with the glottis opened in the right lateral posture. The physiotherapist will not intervene in this arm.

DEVICE

PEP

The subject will be asked to exhale through a positive expiratory pressure (PEP) device (Threshold PEP) while being in the right lateral posture.

BEHAVIORAL

1L-Tidal-Breathing

The subject will be asked to breath with a fixed tidal-breathing of 1 liter per breath (monitored via a spirometer) while being in the right lateral posture.

BEHAVIORAL

Spontaneous Breathing

The subject will be asked to breath spontaneously while being in the right lateral posture.
