Positive pressure airway secretion-clearing device

Positive pressure airway secretion-clearing devices are handheld, reusable tools that help patients with lung conditions clear mucus or phlegm by generating positive expiratory pressure (PEP). When a patient exhales into the device, it creates vibrations—through mechanisms like oscillating balls or bubbles—to loosen secretions, making them easier to cough up and improving lung function in conditions like COPD or cystic fibrosis.

These devices are typically regulated as medical devices, often requiring compliance with safety and performance standards depending on the jurisdiction. They are designed for both clinical and home use, serving as single-patient tools to aid respiratory therapy. Classification varies by region, but they are generally considered for use in managing chronic or acute lung diseases.
