Effects of SIMEOX on Static Hyperinflation in Patients With COPD

Not Applicable

Completed

• Conditions: Pulmonary Disease, Chronic Obstructive

• Registration Number: NCT04157972
• Lead Sponsor: Cliniques universitaires Saint-Luc- Université Catholique de Louvain

Brief Summary

This study will investigate the effects on the SIMEOX technology on static hyperinflation in patients with chronic obstructive pulmonary disease (COPD).

Detailed Description

This is a crossover study assessing the short-term effects of SIMEOX and PEP device on static hyperinflation in patients with COPD.

Patients will perform lung function tests (to assess the residual volume and functional residual capacity) before, after and 30 minutes after a 20-min long session of SIMEOX or PEP (depending of randomization).
