Cough Assist


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:



  • Amyotrophic lateral sclerosis

  • Spinal muscular atrophy

  • Muscular dystrophy

  • Myasthenia gravis

  • Spinal cord injuries



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.
