Many people with neuromuscular impairments (such as muscular dystrophy, amyotrophic lateral sclerosis, and spinal cord injury) are not able to breathe on their own and require a ventilator (respirator) to sustain life. The ventilator must also be used to support speech; however, ventilator-supported speech is often abnormal because the way the ventilator delivers the breath is different than the way that a healthy individual moves air in and out of the lungs. Some work has been done to improve speech in ventilators that are connected to the person via a tracheostomy (Garguilo, et al. 2013; Hoit, et al. 2003; Lohmeier and Hoit 2003; Prigent, et al. 2010). However, in medical practice there has been a recent movement away from tracheostomy and an increased use of a noninvasive positive-pressure ventilation (NPPV) where the ventilator-delivered air is routed through the mouth and/or nose. This form of ventilation poses a completely different set of challenges for speaking and swallowing, including coordination of speaking and swallowing with breathing.
In this presentation, we will provide an overview of NPPV, along with preliminary data from a qualitative study examining the impact of NPPV on speaking and swallowing in individuals with neuromuscular disorders.
Learner Outcomes: At the completion of this presentation, participants will be able to describe selected forms of NPPV, understand the potential impact of various forms of NPPV on speaking and understand the potential impact of various forms of NPPV on swallowing.
