Many people have been familiarising themselves with CPR and other life-saving techniques following the shocking scenes seen by millions around the world at the Euro 2020 championships.
Denmark's Christian Erikson collapsed during his team's game with Finland, suffering a cardiac arrest.
"He was gone. We did cardiac resuscitation, it was a cardiac arrest," said Danish team doctor Marten Boesen.
"How close were we to losing him? I don't know, but we got him back after one defib [defibrillation] so that's quite fast.
"The examinations that have been done so far look fine. We don't have an explanation to why it happened."
Automated External Defibrillators (AEDs) are located in many public places and could be crucial to saving someone's life if they are having a sudden cardiac arrest.
AEDs are easy to use, compact, portable and very effective. They guide the operator through the process by giving verbal instructions and visual prompts. They are safe and will not allow a shock to be given unless the heart’s rhythm requires it.
The Northern Ireland Ambulance Service has mapped where AEDs are located across Northern Ireland. Although it is not a tool to be used in an emergency to locate your nearest AED, its purpose is to support members of the public and organisations in understanding where AEDs across Northern Ireland are located. For example, you may be wishing to place an AED in your community and this will tell the location of existing AEDs.
There are some 272 AEDs in the Armagh City, Banbridge and Craigavon borough. Here, we've shown you where the AEDs are located around Lurgan and Craigavon.
