cough assist device
Mechanical device that helps patients with weak cough reflexes clear airway secretions by providing positive and negative pressure cycles.
Full Definition
A cough assist device, also known as a mechanical insufflator-exsufflator, is a non-invasive respiratory therapy tool that mimics the natural cough mechanism. The device delivers positive pressure to inflate the lungs, followed immediately by negative pressure to rapidly deflate them, creating an artificial cough that helps mobilize and clear airway secretions. This therapy is particularly valuable for patients with neuromuscular disorders, spinal cord injuries, or other conditions that impair their ability to generate effective coughs. The treatment helps prevent pneumonia and other respiratory complications by maintaining airway clearance.
Usage
Usage note: Hyphenate as shown; avoid 'cough-assist' as a standalone adjective.
