Brief Summary:


Many patients with respiratory failure related to neuromuscular disease receive chronic invasive ventilation through a tracheostomy. Improving quality of life, of which speech is an important component, is a major goal in these patients. The investigators compared the effects on breathing and speech of low-level positive end-expiratory pressure (PEEP, 5 cm H2O) and of a Passy-Muir speaking valve (PMV) during assist-control ventilation.


Flow will be measured using a pneumotachograph. Microphone speech recordings were subjected to both quantitative measurements and qualitative assessments; these last consisted of a perceptual score and an intelligibility score determined by two speech therapists using a French adaptation of the Frenchay Dysarthria Assessment.
