said by cdru:An AED wouldn't even charge and fire if the person still has a heart beat, which the baby did.
Who told you that? An AED will fire in cases of tachycardia and fibrillation. That's the whole point of an AED. If you learned otherwise you should fire the person doing first aid training for your company. From Wikipedia, emphasis mine:
An automated external defibrillator is used in cases of life threatening cardiac arrhythmias which lead to cardiac arrest. The rhythms that the device will treat are usually limited to:
1. Pulseless Ventricular tachycardia (shortened to VT or V-Tach)[1]
2. Ventricular fibrillation (shortened to VF or V-Fib)
In each of these two types of shockable cardiac arrhythmia,
the heart is active, but in a life-threatening, dysfunctional pattern. In ventricular tachycardia, the heart beats too fast to effectively pump blood. Ultimately, ventricular tachycardia leads to ventricular fibrillation. In ventricular fibrillation, the electrical activity of the heart becomes chaotic, preventing the ventricle from effectively pumping blood. The fibrillation in the heart decreases over time, and will eventually reach asystole.
