Efficacy and Safety of Non-invasive Ventilation by Calibrated Leak in the Treatment of Respiratory Acidosis in ICU

Not Applicable
Terminated
Conditions
Respiratory Acidosis in ICU Patients
Registration Number
NCT02630784
Lead Sponsor
University Hospital, Grenoble
Brief Summary

VNI Versus is a clinical, prospective, randomized, cross over study, aiming to compare two mechanical ventilators during non-invasive ventilation for patient suffering from respiratory acidosis.

This study will compare a dedicated ventilator for Non Invasive Ventilation (NIV) functioning with a turbine and with vented mask (exhalation by a calibrated leak) and a dedicated ventilator for Intensive Care Unit (ICU), functioning with non-vented masks and an exhalation valve.

Patient will be randomized before the first NIV session lasting 2 hours. After a two hours wash-out, a second NIV treatment will be delivered with the other ventilator for duration of 2 hours.

Arterial blood samples will be collected at the beginning and the end of each session of NIV. A transcutaneous captor of dioxide carbon pressure (PCO2) will also be used for patient monitoring.
