Local DEA app: Saving lives with accessible and well-located automated external defibrillators.

Purpose: Developing technological solutions to reduce care delay and mortality in out-of-hospital cardiac arrest (OHCA) cases is a challenge both in Brazil and worldwide. The aim of this study was to develop and validate a geolocation application for locating automated external defibrillators (AEDs) in the urban area of a medium-sized city in southern Brazil.

Methods: A mobile application was developed to locate AEDs in public places, indicating the best route to the nearest AED with an intuitive design for emergency use.
