AUTOMATED EXTERNAL DEFIBRILLATION Rationale for Early DefibrillationThe most frequent initial rhythm in cardiac arrest is ventricular fibrillationThe most effective treatment for ventricular fibrillation is defibrillationthe probability of successful defibrillation of ventricular fibrillation diminishes rapidly

PRINCIPLE OF EARLY DEFIBRILLATIONEmergency personnel who respond to cardiac arrests should be trained to operate, equipped with, and permitted to operate a defibrillator

AEDS PERMIT WIDESPREAD USE OF EARLY DEFIBRILLATION

IMPROVING SURVIVAL FROM CARDIAC ARREST INVOLVES THE CHAIN OF SURVIVAL CONCEPTEarly accessEarly CPREarly defibrillationEarly ACLS

STEPS FOR OPERATION OF ALL AEDSTurn on powerAttach device to patientInitiate analysis of rhythmdeliver shock, if indicated

SPECIAL FEATURES OF AEDSMicroprocessor-based circuits that analyze rhythm for tachyarrhythmiasAttachment to patient through dual-function (monitoring and defibrillating) adhesive padsRequirement that CPR and all contact with patient cease during AED operationInability to operate in analyze mode unless patient is in full cardiac arrest
