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