CARDIAC ARREST
Our interest is in bystander administration of Narcan, which has not been well studied. Most of the existing research on bystander emergency response is related to automated external defibrillators (AEDs). An AED is the leading emergency technology used for cardiac arrest. Bystander training in cardiopulmonary resuscitation (CPR) and AEDs is common and typically performed on manikins in controlled environments. The fundamental components of bystander training identified in AED research were used to inform the methodology of our study.The majority of untrained laypeople are not able to effectively operate an AED, despite its intention to be usable by all people in emergencies [Likewise, Biancardi et al. [When providing instructions, it is important to avoid cognitive overload for the bystander. Even if direct verbal instruction is used, the prompt may not be effective if it is accompanied by complex videos or diagrams. Ettl et al. [
