  Purpose
Mechanical ventilation is one of the only treatment that has improved survival of patients with neuromuscular respiratory failure. As disease progresses, some patients may require longer ventilation period. Non invasive mechanical ventilation is the preferred method of ventilation but it may interfere with speech and communication of patients who require ventilation throughout the day. The investigators are evaluating the effect on speech and communication of a ventilation device which allows patients to momentarily and voluntarily withhold ventilation if they want to speak. This should allow the patients to have a more fluid speech.

Condition Intervention
Neuromuscular Disorder Respiratory Failure Device: Elysee 150 ventilator Device: Elysee 150 ventilator with a ventilation switch control

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Optimizing Communication During Nasal Mechanical Ventilation

Further study details as provided by Helene Prigent, Centre d'Investigation Clinique et Technologique 805:

Primary Outcome Measures:
  • Impact of patient's ventilation control on speech efficiency [ Time Frame: 1 hour 30 min ]
    Speech efficiency will be evaluated while using a ventilator which allows the patient to constantly control when he wants to be ventilated Speech evaluation is based on speech rhythm and text reading duration


Secondary Outcome Measures:
  • Patient ventilator synchronisation during speech [ Time Frame: 1hour 30 min ]
    Evaluated with the variation of respiratory frequency during speech, the number of auto-triggered ventilation cycles during speech.

  • User friendliness of the ventilator during speech [ Time Frame: 1hour 30 min ]
    evaluation of user friendliness by the patient using a visual analogical score

  • Respiratory comfort during speech [ Time Frame: 1hour 30 min ]
    evaluation of user friendliness by the patient using a visual analogical score and the Borg score

  • Speech comfort during ventilation [ Time Frame: 1hour 30 min ]
    evaluation of speech comfort during ventilation by the patient using a visual analogical score
