Innovent Medical Solutions' technology for noninvasive airway clearance aids secretion management in critical care ventilated patients. Itspatented combination of a suction unit and a disposable valve simulates a natural cough in ventilated patients in order to clear their secretions noninvasively. As compared to catheter suction, Innovent's system is completely non-traumatic, does not introduce infection into the airways, can clear areas of the lung inaccessible to catheters, and may enable patients to avoid endotracheal intubation completely.
