| Summary: | There has been an increase in use of noninvasive positive-pressure
ventilators (NPPV) to provide breathing assistance to people who are limited
in their ability to breathe on their own as a result of neuromuscular
impairment. To date, essentially nothing is known about how NPPV
inspirations are used to power speech, beginning with whether or not
individuals actually use their NPPV device for the purposes of speech. This
project aimed to quantify inspirations that power speech in users of NPPV,
and the amount of speech that followed NPPV powered speech. While
participants claimed that NPPV helped them speak, NPPV was found to
power only 37% of their speech utterances. For those who did use NPPV to
power speech, NPPV-assisted inspirations were sometimes followed by a
greater number of syllables compared to those that followed non-assisted
inspirations (up to 35% greater). Preliminary results indicate that NPPV
users do not take advantage of the potential benefits of powering speech
with their ventilator and that speech-language pathologists may be of
assistance in helping them do that. |
