If you look around the public places you visit, you are likely to find an AED. An AED is both sophisticated and easy to use, providing lifesaving power in a user-friendly device. This makes the device useful for people who have no experience operating an AED and allows successful use in stressful scenarios. However, proper use of an AED is very important. The purpose of defibrillation is to "reset the electrical systems of the heart allowing a normal rhythm a chance to return."
Initial dose should be 2 to 4 J/kg (4 J/kg for refractory VF). Ideal energy levels yet to be determined.
2010 AHA GUIDELINES FOR AED USE
For 1-8 year olds, an AED with a pediatric dose to attenuator system should be used (if available). For infants under 1 year old, manual defibrillation is preferred. If neither pediatric dose attenuator or manual defibrillator available, a standard adult AED may be used.
