What is an AED?

An AED (or Automated External Defibrillator), is a vital life-saving medical device used to help those experiencing sudden cardiac arrest. AEDs are designed to deliver an electrical shock, or defibrillation if needed. The shock helps the heart re-establish an effective rhythm. While being a sophisticated piece of equipment, they are simple to use. 

The Mediana Heart On A15 and A16 AEDs are easy to use. The device literally talks the user through the process of delivering a shock with clear voice prompts, which means anyone can quickly make a difference by using them.

How do I use an AED?

AEDs are designed to be easy to use in an emergency. The Mediana A15 and Mediana A16 can be quickly and easily used by anyone. Simply by opening the lid on the AED starts voice instructions that literally talk the user through the process of using the device, applying the pads, and delivering a shock. An online course is also available!


Cardiac arrest can affect anyone at any time. Each year there are more than 30,000 out-of-hospital cardiac arrests in the UK, but fewer than one in ten people survive. Each minute that passes without CPR or access to an AED reduces the chances of survival by 10%. An AED is no replacement for professional emergency medical care but together with CPR, it can help to keep a patient alive while waiting for the emergency services to arrive.  

With greater demands on the NHS, ambulance response times are at record highs, there has never been a greater need for easy-to-access AEDs.
