The Effects of Oscillatory Positive Expiratory Pressure (OPEP) Therapy in Patients With COPD

COPD

The goal of this non-pharmacologic interventional study is to learn if Oscillatory Positive Expiratory Pressure (OPEP) therapy can improve disease impact and respiratory system dynamics in patients with COPD. The main questions it aims to answer are:

Is OPEP therapy able to improve the impact of cough symptoms as measured on a validated symptom score? Is OPEP therapy able to improve the properties of the lung (called reactance) as measured by oscillometry?

Researchers will compare the results of the same tests performed before and after 4 weeks of OPEP treatment to see if OPEP treatment improves cough symptoms and lung mechanics.

* Participants with COPD will complete in-person baseline tests and will then receive the smart OPEP device.
* These participants will then use the smart OPEP device at home, at least twice a day, for 4 consecutive weeks.
* Finally, these participants will return to complete in-person end-of-study tests.
