Intellivent Versus Conventional Ventilation (Intellivent)
Comparative Monocenter RCT Comparing Safety and Efficacy of an Automated Closed-loop Oxygenation and Ventilation(IntelliVent® System - HAMILTON MEDICAL AG) With Non-automated Conventional Ventilation and Oxygenation
Partial automation of mechanical ventilation in resuscitation has been available for several years. New modalities are being developed to completely automate ventilation and oxygenation parameters (IntelliVent®.
This pilot study compares over a 48h period the safety and efficacy of IntelliVent®, versus a conventional ventilation modality.

Detailed Description
Rational: Partial automation of mechanical ventilation in resuscitation has been available for several years. It can deliver a continuous ventilation adapted in real time to the patient's clinical condition,and decrease care workload and ventilation weaning duration. New modalities are being developed to completely automate ventilation and oxygenation parameters (IntelliVent®) and preliminary studies show that over short periods (2 to 4 h) such a system can ventilate patients more optimally and more safely, with a better ventilation efficiency (comparable effect on gas exchanges for a less "aggressive" ventilation). This pilot study compares over a longer period (48 hours), the safety and efficacy of IntelliVent®, versus a usual ventilation modality.
Type of study: Monocenter, comparative, prospective, randomized, parallel study.
Objective: To assess IntelliVent® safety, efficacy, and care workload.
Assessment criteria:
- Safety is assessed by measuring the number of times it is necessary to manually intervene on the ventilator settings because for one the following parameters: A range SpO2, EtCO2, plateau pressure (Pplat), tidal volume (VT), respiratory rate (RR),values considered as non-optimal, as defined a priori and consensually by a panel of experts.
- Efficacy, in terms of ventilation, is assessed by the time spent within a range EtCO2 and Pplat and VT and RR values considered as optimal, as defined a priori and consensually by a panel of experts.
Efficacy, in terms of oxygenation, is assessed by the time spent within a range SpO2 values considered as optimal, as defined a priori and consensually by a panel of experts.
- Care workload is assessed by the number of ventilator setting adjustments by nursing staff in each group.
Number of subjects: 80 patients receiving invasive mechanical ventilation for acute respiratory failure.
Methods: The selected patients presenting with inclusion criteria are ventilated either with IntelliVent® or with the unit's usual ventilation following a random selection.

Experimental: Intellivent
Intellivent is a ventilatory mode included in ventilator S1, Hamilton Medical. Intervention: the patient is ventilated with the same ventilator than in the conventionnal group; but the "ASV-Intellivent" ventilation has to be activated via a dedicated key on the ventilator screen. IntelliVent® activation requires selecting the kind of patient: ARDS, COPD and whether hemodynamic instability exists. The initial settings are IntelliVent® by default settings (% MV: 110%, PEEP: 5 cm H2O, FiO2: 60% - 100% in case of ARDS). Therefore modification of these various parameters is automatic. FiO2 and PEP are modified according to SpO2; %MV according to EtCO2. |
Intellivent allows an automatic adjustment of the following parameters: FiO2, PEEP and %VM according to adjusted parameters: Size, SpO2 and EtCO2
