Study of 7000 patient in Paris, France, and Seattle, Washington.
Three criteria that predict, with almost 100% PPV, of death prior to hospital discharge:
- Arrest not witnessed by EMS personnel.
- Non-shockable rhythm on initial evaluation.
- No ROSC by 3rd dose of epinephrine 1mg.
Of the 2800 patients who met all 3 criteria, only 1 survived to hospital discharge.
