In region of Moselle, Geocœur was launched in 2021. It is an innovative improvement for defibrillators which are devices used to treat cardiac arrhythmias by generating electric shocks through the chest of a patient suffering from such afflictions.
Modern automated external defibrillators (AED) are often found in public spaces as they require little to no training to be used. An onboard computer analyses the heart rhythm of the patient and then suggests a shock or not. All the user has to do is apply the defibrillation patches on the patient chest and follow the instructions of the machine to perform cardiopulmonary resuscitation (CPR) and, if needed, defibrillation.
Enters Geocœur, which adds a layer of efficiency in this process. The Geocœur devices are simple alarms placed right above AEDs. They are connected to the emergency medical services line and are activated as soon as a call for cardiac arrest is located nearby. This alerts nearby passers about the issue and allows them to scan the tag with their phone to receive further instructions on where exactly is located the victim.

A typical Geocœur panel equipped with a sound alarm, light indicator and 4G LTE chip connecting it to the internet.
It is then up to the person to get the AED to the patient. This significantly increases the chances of the defibrillator arriving earlier onset as irreversible brain damage occurs mere minutes after a cardiac arrest.
The company behind Geocœur has so far deployed 30 of these devices and aims to expand more in the Marne department.
