What is an Automated External Defibrillator?
An Automated External Defibrillator (AED) is a device that can assess a person’s heart rhythm, determine if it abnormal, and if necessary, administer an electric shock to restore it back to a normal rhythm. The computer algorithm in an AED is designed to assess the patient’s heart rhythm. The AED differentiates normal from abnormal heart rhythms and advises a shock only if needed. Visual and/or audible prompts guide the user through the exact procedure.
