Mucus Clearing Devices
Mucus clearing devices are specialized respiratory aids designed to help patients mobilize and evacuate excessive bronchial secretions. In healthy individuals, the mucociliary escalator and cough reflex work together to transport mucus out of the airways. However, in patients with chronic respiratory conditions—such as cystic fibrosis, bronchiectasis, chronic obstructive pulmonary disease (COPD) or neuromuscular weakness—mucus can accumulate, obstructing airflow and predisposing to infection. Mucus clearing devices support or augment natural clearance mechanisms by applying mechanical forces, oscillations, or suction to loosen tenacious secretions, facilitate cough, and improve ventilation.
