In general, there are two types of AEDs: fully automated and semi-automated. Semi-automated AEDs: A. automatically charge up and deliver the appropriate electrical shock. B. have only one operational button. C. allow the operator to attach the device to the patient, push a button to turn on the power, and let the device do the rest. D. indicate to the operator when a shock is advised so he can push another button to deliver the shock.
