Slide3Why is Defibrillation Important?
The problem of sudden cardiac arrest!
The background to defibrillation and AEDs
Slide4AEDs & 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.

Slide6Common 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

Slide9Sudden 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
A
ll 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 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
What is defibrillation?
Slide16Biphasic defibrillation
Current flows in
two
phases; first in one direction from one pad, the current then reverses from the other pad.

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?
Overview

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
Testing / Service

8-year warranty
Training aids available
Slide21Independent 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
Slide22CARDIAC SCIENCE |

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.
