Oscillatory Positive Expiratory Pressure (OPEP) Therapy clinical trials

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

This study looks at whether a special breathing device called OPEP can help people with COPD breathe better and cough less. Participants will use the device at home for four weeks, and researchers will compare their breathing and cough symptoms before and after.
