The study took place in Kanazawa city, where ambulances
without FAST™ (non–FAST™-equipped) were being progressively replaced by new FAST™-equipped

compared in the subgroup of OHCAs managed by emergency medical technicians without tracheal intubation
or epinephrine administration. The primary end-point of this study was one-year (1-Y) survival
