Aschauer et al reported a tool for predicting survival of a patient having an out-of-hospital cardiac arrest. The authors are from the Medical University of Vienna.
Patient selection: out-of-hospital cardiac arrest
Outcome: 30-day mortality
Parameters:
(1) min2srosc (minutes between cardiac arrest and return of spontaneous circulation
(2) age in years
(3) shockable rhythm
(4) adrenaline dose in mg
