The background to defibrillation and AEDs Why is Defibrillation Important? The problem of sudden cardiac arrest!

AEDs & SCA Sudden Cardiac Arrest (SCA) is an arrhythmia- abnormal heartbeat- which causes the heart’s normal rhythm to suddenly become chaotic. The heart can no longer pump oxygenated blood effectively around the body and the victim collapses, becomes unresponsive, and stops breathing. AED = "Automated External Defibrillator." An AED is used to administer an electric shock to a person who is having a cardiac arrest in order to allow the heart to reset to a normal rhythm.

Common causes of Sudden Cardiac Arrest Common causes for sudden cardiac arrest include but are not limited to: Asphyxiation, drowning, circulation problems, drug effects, electrocution, heart diseases, hypothermia, metabolic changes, respiratory problems, trauma to the chest Sources: Office for National Statistics; World Health Organisation; Department of Transport

Sudden Cardiac Arrest Defibrillation is the only way to treat a Sudden Cardiac Arrest The chance of survival drops by 10% every minute if victim is not treated – making early defibrillation crucial in the chain of survival. The chain of survival must be complete to maximise patient survival. If defibrillation is achieved within the first 3 minutes the chances of survival rise up to 70%. Early defibrillation is the weak link.

LIFE THREATENING ARRYTHMIAS All Automated External Defibrillators (AEDs) are designed to treat a patient that is: Unresponsive Not breathing normally AEDs treat two specific fast arrythmias: Ventricular fibrillation (VF) Pulseless ventricular tachycardia (VT) 90% of SCA patients initial rhythm is Ventricular Fibrillation Ventricular Fibrillation (VF) Ventricular Tachycardia (VT)

The importance of CPR Chest compressions/rescue breathing 30:2. Keeps oxygenated blood flowing to brain and heart to ‘buy time’. Push hard and fast. Min depth 5cm at 100 to 120 per min. Important part of the Chain of. Survival

What is defibrillation? The objective of defibrillation is to stop the wave-fronts of VF Current delivered across the heart Successful defibrillation “depolarizes” the heart’s cells Depolarization allows the cells to “reorganize” Defibrillation is the ONLY effective cure for VF! CONTRARY TO PUBLIC BELIEF, YOU ARE NOT ‘JUMP-STARTING’ THE HEART

Biphasic defibrillation Current Flow Biphasic defibrillation Current flows in two phases; first in one direction from one pad, the current then reverses from the other pad. Biphasic defibrillators incorporate two-way current flow in which electrical current flows in one direction, then reverses and flows in the opposite direction.

Overview When purchasing the AED one should consider: Will the AED work when I need it? Is it reliable? Am I going to use it in a stressful situation? Is it easy to use? Will the AED deliver the most effective treatment?

Testing / Service AEDs have 3 critical components: Battery Device electronics and software Pads It is vital that these components are tested regularly. All Defibtech AEDs carry out tests automatically on the following basis: Daily Weekly Monthly Quarterly

Lifeline AEDs Highly durable – tested to military standards for shock & vibration, drop tested on all corners & faces, crush tested to 450kg. Lifeline View is industry unique full colour video screen – including visual CPR coaching. On-screen instructions mean anyone can use- people who are heard of hearing; don’t speak English as their first language; in very noisy environments 1.9kg fully integrated unit – lightweight, portable, no confusing lids or moving parts. Rubber-grip handle big enough for a gloved hand. Easiest unit to use on the market – proven by independent usability study. Long life battery options Future proof – Free software upgrades when resuscitation guidelines change 8-year warranty Training aids available

Independent Usability Study The University of Illinois took the 5 leading AED manufacturers and tested them on 125 non medically trained people: The Defibtech AED came out as the easiest to use following this study 92% of users successfully administered a shock with the Defibtech AED, compared to 84% Philips, 72% for Medtronic (Physio Control) and Zoll, 36% for Cardiac Science Conclusion of the study : The Defibtech AED was more successfully used by non-medically trained bystanders than the other 4 leading manufacturers

Safety and Effectiveness No recorded cases of harm to rescuers and bystanders caused by an AED Part of the FDA test - the failsafe will not allow a shock to be delivered unless VF is detected AEDs have failsafe that is able to dump shock right up to the last second if someone touches the patient The quicker a shock is delivered to the SCA victim the more likely he or she will survive (<4 seconds). In SCA the only effective therapy is defibrillation. A reliable, easy to use and user friendly AED is paramount in increasing survival from SCA.
