Abstract

Defibrillator electrodes having an identification element and a circuit which indicates to an AED the weight range of the patient being rescued. When the AED detects the presence of pediatric electrodes, it may select a different set of voice prompts that are specifically suited to a pediatric patient and/or it may select a pediatric dosage of electricity for the therapeutic shock.
