CPR has been refined by leading researchers and performed by many rescuers. Without a doubt, the procedure helps to save many lives. However, CPR alone prolongs life, rather than saves it. The procedure simply buys the victim a few more minutes of precious time. That's where defibrillation comes in.
Defibrillation is the key to survival from a cardiac arrest.
In other words, defibrillation stops the lethal chaotic activity of the heart momentarily allowing the sinus node to resume its normal pace. Debunking the Myths AEDs were born from the need of the earliest possible defibrillation to restore the SCD victim's normal circulation. Unfortunately, myths have arisen with this newest generation of AEDs. The only effective means of conversion is through early defibrillation. And, of course, the earliest defibrillation will yield the best survival.
