Abstract
Recently, it is reported that nasal-mask intermittent positive pressure ventilation (NIPPY) during sleep is most effective and non-invasive treatment of respiratory failure in patients with Duchenne muscular dystrophy. Although this system is excellent, longterm nasal ventilation causes tissue damages, especially persistent nasal bridge ulceration from a mask. A commercially available nasal plug (Puritan-Bennett Co.) resolves this problem. This nasal plug-IPPV minimized skin pressure and tissue damage, and achieved high effectiveness.
