From: A regional trauma system to optimize the pre-hospital triage of trauma patients
Grading system for on-scene evaluation of trauma victims, according to the French Vittel triage criteria [ 8 , 9 ]. Hemodynamic instability is defined as a systolic arterial blood pressure of less than 90 mmHg despite the use of vasopressors and more than 1 L crystalloid fluids and/or a pre-hospital blood transfusion. Respiratory instability is defined as a SpO2 < 90% despite the use of mechanical ventilation and/or the use of a face mask with high-flow oxygen. GCS: Glasgow coma scale; SpO2, pulse oxygen saturation.
