Optimizing Communication During Ventilation

Centre d'Investigation Clinique et Technologique 80510 enrolled

Overview

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.

Poincaré Hospital. * Non invasive mechanical ventilation for a duration equal or above 14h per day. * Patient in a steady state at the time of the study * written informed consent Exclusion Criteria: * patient's refusal to participate to the study * Inability to read the selected text * Inability to use the ventilator switch * Inability to cooperate * Hemodynamic instability * Acute respiratory failure * No affiliation to social security

Outcomes

Primary Outcomes

Impact of patient's ventilation control on speech efficiency

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

Time frame: 1 hour 30 min

Secondary Outcomes

Patient ventilator synchronisation during speech

Evaluated with the variation of respiratory frequency during speech, the number of auto-triggered ventilation cycles during speech.

Time frame: 1hour 30 min

User friendliness of the ventilator during speech

evaluation of user friendliness by the patient using a visual analogical score

Time frame: 1hour 30 min

Respiratory comfort during speech

evaluation of user friendliness by the patient using a visual analogical score and the Borg score

Time frame: 1hour 30 min

Speech comfort during ventilation

evaluation of speech comfort during ventilation by the patient using a visual analogical score

Time frame: 1hour 30 min
