*Patients were either not intubated (NoEDMV) or intubated (EDMV) and received propofol infusion + any amount of narcotic pain medication (PROP + Pain), no sedation (NoSedation), proprofol infusion only (OnlyProp), or any amount of benzodiazepine (OnlyBenzo), BPdepart - triage: Absolute change in blood pressure between departure from the ED and triage, BPSV: Successive variation of blood pressure, BPCV: Coefficient in variation of blood pressure, BPhigh - low: Absolute difference of high and low SBP during ED stay, BPSD: Standard deviation of blood pressure, Depart: Departure from emergency department, ED: Emergency department, GCS: Glasgow Coma Scale, ICU: Intensive care unit, SD: Standard deviation, EDMV: Invasive mechanical ventilation in the ED
