anterior–posterior, immediately at the beginning of the resuscitation and aid in preventing delays in rhythm checks and treatment In addition, many defibrillators, when pads are placed anterior–posterior, can give feedback to the user on key CPR parameters, such as depth and rate of compressions, and adequacy of release The initial dose for defibrillation is J/kg, increased to J/kg if the first attempt is unsuccessful Automated external defibrillators (AEDs) automatically interpret the cardiac rhythm and, if pulseless VT/VF is present, advise the operator to deliver a charge They are small, easy to use, and have batteries that last for years For patients with pulseless VT/VF, early rapid defibrillation is the treatment of choice AEDs have been proven to be highly sensitive and specific when used on adults, and there is good evidence that its use in the out-of-hospital setting has resulted in a dramatic improvement in survival of adults with VF Pediatric-based ECG rhythm analysis algorithms for AEDs are 99% sensitive and specific for determining shockable and nonshockable pediatric rhythms Available AEDs deliver a standard adult charge between 150 and 200 J; they can be used for children >1 year of age An attenuating pediatric electrode system is available which decreases the charge delivered to 50 J and is preferred if available for children to year old For infants
