In addition to the AEDs themselves, technology applications including mapping AEDs and automated alerting of nearby lay first responders have the potential to significantly strengthen the chain of survival
and increase survival rates.
"You are the first step in the chain of survival
," she said.
The chain of survival
was fully described and delineated in the 1992 guideline for CPR and emergency cardiac care by the American Heart Association (AHA).
Rapidly implementing the "chain of survival
" model (2) can help increase the chances of survival from sudden cardiac arrest.
Most cardiac arrests in adult patients are due to ventricular fibrillation (VF) or cardiac-related causes, and early defibrillation improves survival of such patients (1,2) and is therefore an important part of their immediate treatment (combined with the other links of the chain of survival
for both in- and out-of-hospital cardiac arrest).
"We need money urgently to strengthen the Chain Of Survival
all around Ireland.
Steve Walton, the brigade's Redcar District Manager said: "All members of the public can be taught life saving skills which could form a vital link in the chain of survival
Despite renewed worldwide interest in implementing effective resuscitation procedures in the pre-hospital environment, with emphasis on the much-acclaimed 'chain of survival
', and despite increased education and awareness of the general public and the training of health care providers in the use of the automated external defibrillator (AED), an unacceptably high number of deaths from cardiac arrest still occur outside hospital.
AHA, the American Red Cross (ARC), and the National Safety Council (NSC) rate early defibrillation as the most critical link in the chain of survival
. It is easy, safe, and effective, but it has to be done quickly because survival rates drop by seven percent to 10 percent for each minute that elapses between onset of SCA and the first defibrillation shock.
Feingold says, "a vital link in the chain of survival
can be strengthened, and more victims of cardiac arrest will have a fighting chance at survival."
The AHA identifies the critical steps of response to a cardiac arrest as the "chain of survival
." The four links in this chain are: (a) early access, (b) early CPR, (c) early defibrillation, and (d) early advanced cardiac life support (ACLS).
