Emergency Defibrillator (AED) Instructions For Use

General News

HEARTSAFE® Life Saving Defibrillator

In the event of a suspected cardiac arrest, the following procedure should be used: 

1. Call 999 or 112 and ask for the ambulance service. 

2. When asked by the operator, please give the telephone number from where you are calling and the location of this cabinet which is:

An Example:

Cabinet No. 12345

Address Line 1

Address Line 2




3. The operator will ask a series of questions which you will need to answer to the best of your ability. This will only take a few moments and will not delay the ambulance. 

4. The operator will then provide you with the access code to open the cabinet (if the AED is located inside an external cabinet and registered with the ambulance service) or access the nearby defibrillator.

5. The defibrillator and resuscitation pack should be removed from the access point and the ambulance service will stay on the line and give verbal instruction if required. 

6. Switch on the defibrillator and it will then provide you with verbal instructions for use. 

7. The defibrillator cannot be used incorrectly as it will only deliver a shock to the patient if it detects it is necessary. 

8. There are scissors in the resuscitation pack to assist with removal of clothing and a pocket rescue breath mask for use with ventilations in CPR. 

9. If you are unable or unwilling to give ventilations, simply do “hands only” chest compressions.

Remember THINK safety. 

Look around before pushing the button to shock and SHOUT the command STAND CLEAR SHOCKING and then check to make sure everyone is clear.

What are the facts about Sudden Cardiac Arrest?

Sudden Cardiac Arrest (SCA) is the single most significant cause of death – around 100,000 deaths per year are as a result of SCA. It is estimated 60,000 occur out of the hospital. Less than 5% of sufferers survive a cardiac arrest. With the early use of an Automated External Defibrillator (AED) and effective CPR, the survival rate can increase to 50%. There is a likelihood that cardiac arrests will occur within the population of one of our business/projects whilst workmen, professionals or visitors are on the premises/site.

Many SCA victims can be saved if persons nearby recognise what has happened, summon the ambulance service with the minimum of delay, perform basic cardiopulmonary resuscitation (particularly chest compressions) and use an AED to provide a high energy electric shock to restore the heart’s normal rhythm. Each of these stages is a link in a chain of events that provide the best chance of success, but the critical factor is the speed with which the shock is given.

What are the features of an AED?

Purchasing a defibrillator can be confusing, as the technical ability and performance of the defibrillator may be only understood by trained personnel and sales persons! When in doubt, before money is spent, we recommend you discuss with us your specific requirements of where your defibrillator is to be positioned and who it is likely to be used by.
