CoughAssist is a noninvasive therapy that safely and consistently
removes secretions in patients with an ineffective ability to cough
(peak cough flow <270 l/m).
Typical CoughAssist patients include those with the following
conditions:
CoughAssist clears secretions by gradually applying a positive
pressure to the airway, then rapidly shifting to negative pressure.
The rapid shift in pressure produces a high expiratory flow,
simulating a natural cough.
