An automated external defibrillator could save your life

Sudden Cardiac Arrest (SCA) is an indiscriminate killer with a dismal survival rate of around 8% in the United Kingdom (UK). While half of victims are elderly and over the age of 67, SCA can strike anyone, anywhere including those appearing to be in excellent health. It’s the leading cause of death worldwide and is responsible for over 60,000 deaths a year in the UK alone.

High-quality CPR and early defibrillation are critical in a cardiac arrest. The ZOLL® AED Plus® automated external defibrillator (AED) is equipped to both shock a victim and support the user in helping the rescuer perform high-quality CPR. The AED Plus uses Real CPR Help® technology to deliver real-time feedback on the chest compressions being delivered and coaches the rescuer to the correct depth and rate using visual and audio prompts. It helps rescuers keep calm and respond appropriately whilst resuscitating a victim of sudden cardiac arrest by instructing them quickly and simply through every step of the rescue process. ZOLL’s Real CPR Help technology has been clinically proven to more than double the survival rate of a cardiac arrest victim1.

The provision of AEDs in the work place and wider community has been rapidly increasing over the last few years and it is estimated that there are over 10,000 deployed across the UK. “Over the last three years, we have seen consistent growth in the AED market in the UK with communities and businesses beginning to realize the importance of these life-saving devices,” said Jonathan A. Rennert, President of ZOLL.

AEDs are designed to be easy to use for the “lay rescuer” who is not used to dealing with a cardiac arrest situation on a regular basis. The ZOLL AED Plus has been specially designed to guide the rescuer through the complete Chain of Survival using a unique technology called Real CPR Help. This technology combines visual and audio prompts to encourage the rescuer to “PUSH HARDER” where necessary to ensure they are reaching the correct depth of 5-6cm2. It also features an adaptive metronome which will gradually bring rescuers up to the correct rate of 100-120 compression per minute2.

What many people don’t realise is that in about half of all rescues performed by responders, no shock is advised. If no shock is advised, only high-quality CPR can potentially save a victim. That’s because only high-quality CPR can restore the heart rhythm to one required for a shock to work. Even when an AED says ‘Shock Advised’, high-quality CPR is critical to help pump oxygenated blood to the heart, brain, and other vital organs. Without high-quality CPR and early defibrillation the victim’s chance of survival decreases by 10% every minute — meaning that by the time an ambulance arrives there could be as little as a 20% survival rate! However if high-quality CPR is delivered the survival rate will increase to 60%3. Through Real CPR Help technology the ZOLL AED Plus coaches rescuers through the complete Chain of Survival providing rescuers with the confidence to deliver high-quality CPR.
