AED guide to use
Cardiac arrest occurs when a person’s heart stops pumping blood around the body and they stop breathing normally. Early defibrillation can save a life. The chances of successful defibrillation decline at a rate of about 10% with each minute of delay, so early Cardio Pulmonary Resuscitation (CPR) and defibrillation is essential for survival before emergency services arrive on the scene.
Remember, if in any doubt, call the Emergency services on 999 (or instruct someone else to do this whilst you deal with the immediate situation).
