Automated External Defibrillator (AED)
AEDs are safe and effective, including if the rescuer has had minimal or no training. AEDs may make it possible to defibrillate a heart before ambulance services arrive. CPR providers should continue CPR with minimal interruption to chest compressions both while attaching an AED and during its use. CPR providers should concentrate on following the voice prompts, particularly when instructed to resume CPR, and minimising interruptions to chest compressions. Defibrillation is most effective if completed within 3–5 min of collapse. The device will determine if the victim requires a shock or not - this maybe automated or you maybe asked to press the button when prompted.
If a shockable rhythm is confirmed by the AED you must ensure that all rescuers are not touching the patient and if oxygen is being used, remove up to 1 meter away. Resuscitation steps must then be completed as prompted by the device without delay. Many leisure centres and shops now have these devices in locked cases on external walls of buildings - you must call 999 to get access to the code to use one of these so remember - Check the victim, Call for help, then start CPR.
