This prospective study aimed to identify clinical and laboratory predictors of return of spontaneous circulation (ROSC), 28-day survival, and favorable neurological outcomes in adult patients experiencing out-of-hospital cardiac arrest (OHCA) and brought to the emergency department (ED) by emergency medical services (EMS). Specifically, the prognostic value of hematologic, biochemical, and blood gas parameters on admission was assessed for ROSC, 28-day survival, and favorable neurological recovery. Additionally, the study investigated the influence of key patient-centered and prehospital variables, including demographic features, initial cardiac rhythm, and the timeliness and type of cardiopulmonary resuscitation (CPR), defibrillation, and airway interventions, on overall survival and neurological status.
