Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will investigate the effects on the SIMEOX technology on flow and volume generated in healthy subjects and patients with COPD

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a crossover study assessing the immediate physiological effects of SIMEOX and a PEP device on the exhalation phase in healthy subjects and patients with COPD.

Participants will perform (1) a slow vital capacity, (2) a maximal expiration from total lung capacity to residual volume with SIMEOX, (3) a maximal expiration from total lung capacity to residual volume with a PEP device.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Spontaneous slow vital capacity

Participants will have to perform a slow vital capacity according to the guidelines, from total lung capacity to residual volume

Group Type ACTIVE_COMPARATOR

Spontaneous Exhalation

Intervention Type OTHER

A slow vital capacity maneuver will be performed according to the guidelines, from total lung capacity to residual volume

SIMEOX

Participants will have to perform a passive exhalation using the SIMEOX, starting from total lung capacity and going until achieving residual volume

Group Type ACTIVE_COMPARATOR

SIMEOX

Intervention Type DEVICE

SIMEOX is a device generating a succession of gentle depression at the mouth.

PEP

Participants will have to perform an active exhalation using a PEP device, starting from total lung capacity and going until achieving residual volume

Group Type ACTIVE_COMPARATOR

PEP

Intervention Type DEVICE

A PEP device (Pari-PEP) will be used to provoke a positive expiratory pressure while exhaling, thereby stabilizing the airways during expiration.
