EVapp, which stands for Emergency Volunteer Application, does exactly that. It is a smartphone application that, in case of an emergency, mobilizes trained medical volunteers to overlap the time between it’s occurrence and the arrival of the emergency services. Initially the system will be self-contained: Alarms are sent from the application and received by volunteers using it. In the long term, however, it is our goal to integrate our system with existing emergency dispatching. In this case, mostly volunteers will be using the app. The dispatcher would then decide whether CPR or other urgent medical care could be provided by a nearby volunteer and send out the alarm using our system.
