A Survey of the Public’s Ability to Recognize and Willingness to Intervene in Out‐of‐hospital Cardiac Arrest and Opioid Overdose

Abstract

Out of hospital cardiac arrest (OHCA) and opioid overdose (OD) are two emergencies where prompt recognition and response-typically by untrained bystanders-are critical to ensure positive outcomes. The median incidence of EMS-treated OHCA across ten urban centres in North America is 52 per 100 000, (1) while the US incidence of fatal OD is around 14 per 100 000. (2).
