Could a simple pressure adjustment help ALS patients breathe easier?

This study looks at whether adding a specific pressure setting (PEP) to a standard cough-assist machine can help people with ALS cough more effectively. ALS weakens the muscles needed to cough, raising the risk of lung infections. The trial will compare cough strength with and without the extra pressure in 11 adults with ALS who already use or are starting cough-assist therapy.
