People with COPD who have chronic, moderate to severe mucus accumulation may benefit from a mucus clearance device—a small, handheld object shaped like a pipe.

Blowing into it creates vibrations in the chest that loosen mucus and help medication penetrate the lungs more easily. Some studies suggest that using a mucus clearance device before an inhaled bronchodilator can improve both lung function and exercise capacity while reducing shortness of breath.
