Out-of-hospital cardiac arrest must be discovered in time

A new project seeks to find out if a higher number of cardiac arrests can be discovered during the emergency call and thereby save lives.


When a person experiences cardiac arrest outside hospital it is survival depends on early resuscitation, the so called cardiopulmonary resuscitation (CPR).

Research shows that more than half of bystanders at a cardiac arrest that does not start CPR on their own initiative are willing to do so if encouraged by the personnel receiving the emergency call.

It is thus important to survival that the emergency operator at the emergency central identifies a cardiac arrest so that bystanders can be guided to perform CPR while help is being sent.

This project focuses on investigating and identifying differences in the number of cardiac arrests that are recognized during the emergency call and the pre-hospital treatment on both sides of Øresund, so that experiences can be exchanged and the systems optimized.

The more cardiac arrest that can be identified during the emergency call, the more times life-saving resuscitation can be initiated.

Investigating numbers and differences

In the Capital Region in Denmark it is to be investigated how many cardiac arrests that are identified during the emergency call and what prevents identification. For example, what characterizes an emergency call during which the cardiac arrest is not identified?

Furthermore it is to be investigated if there is an increase in the number of cardiac arrest that has been recognized during the emergency call since health care professionals with a supporting software tool were initiated as receivers of emergency calls in May 2011.

In the Skåne Region the investigation is centered around finding out how many of the 700 cardiac arrests each year that are identified as cardiac arrests upon receiving the emergency call.
