Every second counts. 

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.  

In December 2022 the average reported ambulance response time for chest pain was 93 minutes – five times the target of 18 minutes. The higher priority “life-threatening” category of calls (including those with suspected heart attacks) were also affected. In December 2022 Ambulance crews took almost 11 minutes on average to reach patients – 4 minutes more than the operational target. These figures illustrate how immediate action is required. 

How to do CPR on an adult in 5 steps  

  1. Check for a response. Firmly shake the person’s shoulders and loudly ask if they’re okay.   
  1. Call 999. If the person is unconscious and not breathing, or not breathing normally, start CPR. 
  1. If there is someone with you, ask them to find a defibrillator.   
  1. Start chest compressions. With the heel of your hand in the center of their chest, press down smoothly and firmly at a rate of 2 per second. Try pushing to the beat of Stayin’ Alive by the Bee Gees.   
  1. Use a defibrillator as soon as you can. Follow its instructions carefully while you continue to give CPR.  

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. Whilst 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. 

Why are AEDs Needed in the Workplace? 

  • Research has shown that deploying a defibrillator within 3-5 minutes of collapse can produce survival rates as high as 50%-70%. 
  • Approximately 13% of all workplace facilities are caused by sudden cardiac arrest (SCA).  
  • Only 15% of workplaces in the UK are reported to have a defibrillator on site. 
  • 90% of cardiac arrests occur outside of the hospital. Cardiac arrest can affect anyone regardless of age, anywhere. Employers have a duty of care to their staff, by providing an AED on the premises. 
  • AEDs are low maintenance and can remain in operation for c. 8 years – ready to be used when they are needed most, representing a sound investment by businesses in the safety of their staff and customers. By investing in a defibrillator, you signal to your employees how much you care about their health and safety. 


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 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.   

How Many AEDs does the workplace need?

Access time is an important factor in deciding the number of AEDs required for your workplace. AEDs should be available for staff, customers, and other visitors. All staff should be trained to know where the AED is so they can grab it quickly in an emergency. A maximum 3-minute access time should be considered when placing AEDs in the workplace. The 3 minutes include 90 seconds to locate the device and bring it to the victim and 90 seconds to prepare them and apply the AED to administer a shock.  Large workplaces will need more AEDs  – particularly if they can be accessed by the public. For example, a golf course should have an AED at the clubhouse and a number of AEDs positioned externally at locations around the course that can be accessed quickly in an emergency.
