Mechanical Ventilation Complication, Respiratory Acidosis
Conditions
Brief summary
This is a randomized, open-label study comparing intial settings made by clinicians with settings recommandation made by the VentilO application immediately after intensive care unit admission.The study will allow direct comparison of the frequency of acidosis when patients are ventilated using the parameters of the VentilO application versus parameters chosen by the clinician. The variables determined by the clinician or VentilO will be respiratory rate, tidal volume and resulting minute ventilation.
Interventions
Clinicians will determine respiratory parameters for mechanical ventilation upon arrival in the intensive care unit.
VentilO application (or web platerform) will determine respiratory parameters for mechanical ventilation upon arrival in the intensive care unit.
