This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a medical device called Simeox® to see if it can help people with advanced COPD who have too much air trapped in their lungs. The device applies gentle, high-frequency negative pressure during breathing to help mobilize that trapped air. Researchers want to understand whether a single 20-minute treatment session with the device can immediately improve how much air stays in your lungs after you breathe out.
People with severe COPD often have too much air trapped in their lungs, which makes them feel short of breath and limits how much they can exercise. Reducing this trapped air could significantly improve quality of life, but this particular use of the treatment hasn't been formally studied yet.

You would come in for a single visit where researchers first measure your lung function with breathing tests. Then you would receive one 20-minute treatment session with the Simeox® device while sitting comfortably—the device applies gentle pressure during four series of 10 breathing cycles, with rest breaks as needed. Immediately after the session, your lung function would be measured again to see if the device helped. Throughout the session, medical staff would monitor your heart rate, breathing rate, and oxygen levels to make sure you stay safe.
