In-exsufflator

An in-exsufflator is a portable pneumatic device that uses rapid pressure changes through a face mask to generate high expiratory flow from the lungs, simulating a cough. It is used clinically to assist patients with ineffective coughs—such as those with neuromuscular disorders or paralysis—in clearing retained bronchial secretions and reducing the risk of respiratory complications.

Devices in this category are typically regulated as medical devices intended for respiratory support and secretion clearance. They are supplied as standalone units or as part of integrated respiratory therapy systems and are intended for use under clinical guidance, often in home or institutional settings, to support airway hygiene in patients with impaired cough mechanisms.
