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). 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. Typical CoughAssist patients include those with the following conditions: Amyotrophic lateral sclerosis, Spinal muscular atrophy, Muscular dystrophy, Myasthenia gravis, Spinal cord injuries and Post-polio.
CoughAssist removes secretions from the lungs and reduces the occurrence of respiratory infections.
