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: Intervention Model: Single Group Assignment
Masking: None (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 Prof. Philippe Jolliet, University of Lausanne Hospitals:

Primary Outcome Measures:
  • Patient-ventilator synchrony
    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
    Patient's confort during NIV will be assessed using a visual analogic scale.

  • Ventilatory parameters
    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.

Enrollment: 22
Study Start Date: June 2012
Study Completion Date: April 2013
Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Inclusion Criteria:

  • respiratory failure

Exclusion Criteria:

  • Severe hypoxemia requiring an FiO2 > 0.6
  • Hemodynamic instability : defined as a variation of > 20% in mean arterial pressure (MAP) and heart rate (HR) during the previous 2 hours; the need for high doses of catecholamines (namely > 0.5 mcg/kg/min) and/or the need of major volume resuscitation (more than 2 liters of fluids in 2 hours)
  • Impaired consciousness or absence of patient cooperation;
  • Facial or laryngeal lesions contraindicating the use of NIV;
