Comparison of the effects of 4 ventilators dedicated to NIV (2 home ventilators and 2 ventilators designed for NIV) on patient-ventilator synchrony and comfort in patients admitted in the intensive care unit for respiratory failure and treated with NIV.

Condition Intervention
Respiratoy Failure Requiring NIV Treatment
Device: V-PAP III ventilator
Device: Stellar 150 ventilator
Device: BiPAP vision ventilator
Device: V60 ventilator

Study Type: Interventional
Study Design: Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Comparison of Four Different Ventilators for Noninvasive Ventilation in Terms of Patient-ventilator Synchrony and Comfort

Further study details as provided by University of Lausanne Hospitals:

Primary Outcome Measures:
  • Patient-ventilator synchrony [ Designated as safety issue: No ]
    Patient-ventilator synchrony will be assessed breath by brath on the basis of airway pressure, flow and diaphragmatic electrical activity recordings.

Secondary Outcome Measures:
  • comfort of patient under NIV [ Designated as safety issue: No ]
    Patient's confort during NIV will be assessed using a visual analogic scale.

  • Ventilatory parameters [ Designated as safety issue: No ]
    Tidal volume, respiratory rate, inspiratory time, expiratory time and maximal and mean airway pressure will be measured from the continuous recording of airway pressure and flow.
