Schematic representation of the patient flow in the prehospital period and after admission to the emergency department (ED; A). Blood sampling and near-infrared spectroscopy (NIRS) measurements were immediately initiated upon ED arrival. Cardiopulmonary resuscitation (CPR) time after ED admission was not of influence on the results of the blood analyses or the initial tissue oxygenation index as assessed by NIRS. (B) The variation in the time span between the emergency call and emergency medical service (EMS) team arrival at the location of out-of-hospital cardiac arrest and the duration of prehospital CPR by the EMS for patients with hyperfibrinolysis (HF; n = 13) or without HF (n = 24; table 1).
