©2013 UpToDate ® Print Email Key points regarding the use of Automatic External Defibrillators (AED) in infants and children • VF is the initial rhythm in 9 to 19 percent of children experiencing out-of-hospital cardiac arrests. • Survival with VF is better than survival with asystole. • Defibrillation is indicated for the treatment of VF and pulseless VT. • AEDs are computerized machines that automatically diagnose VF and use voice prompts to instruct rescuers to defibrillate , if appropriate. • AEDs have demonstrated both high sensitivity in detecting VF and high specificity in identifying nonshockale rhythms in children. • For infants and children with VF or pulseless VT, shock delivery may be accomplished by the following devices (in order of preference): Manual defibrillator (when used by a trained provider) AED with a dose attenutation device AED without a dose attenuation device • For in-hospital defibrillation, there are no data comparing manual defibrillators with AEDs or clear guidelines specifying the use of one over the other. • AEDs cannot be used for cardioversion. VF: ventricular fibrillation; VT: ventricular tachycardia.
