Study Design

The workflow involves ongoing communication between the dispatch center and citizen responders via the Heartrunner application (APP), as well as the caller who is at the location of the out of hospital cardiac arrest (OHCA). The first citizen responder is dispatched directly to the OHCA location to perform cardiopulmonary resuscitation (CPR), and the next 4 responders are sent to retrieve automated external defibrillators (AEDs) and bring these to the OHCA location. This facilitates early delivery of both CPR and defibrillation when citizen responders arrive before the ambulance. ACLS = advanced cardiac life support; BLS = basic life support.
