The response time, defined as the interval between call for and
arrival of an ambulance, is one of the major factors associated with
favorable outcomes of out-of-hospital cardiac arrests (OHCAs) [1,2].
Although reducing the response time may improve OHCA outcomes
[3-7], there are only a few ways to achieve it. For example, response
times can be improved by increasing the number of ambulance teams
and fire department offices, or by equipping additional first-line
responders with defibrillators, such as the fire fighters and police
services [8,9].
