Abstract

A defibrillator has a treatment mode and a training mode. The defibrillator includes an energy source; an electrode connector; a controller, including a feature for connecting the energy source to the electrode connector; and training mode features for stimulating the operation of the defibrillator in treatment mode. Also included is a method of operating a defibrillator including the steps of providing a defibrillator (with the defibrillator including a defibrillation energy source, a controller and electrode connectors, and with the controller including circuitry for actuating the defibrillator to deliver a defibrillation shock from the defibrillation energy source to the electrode connectors) and operating the defibrillator in a training mode to simulate delivery of a shock from the energy source to the electrode connectors without delivering a defibrillation shock from the energy source to the electrode connectors. An additional method of operating a defibrillator includes the following steps: providing a defibrillator having automatic or semiautomatic operation; activating the defibrillator to provide therapy to a patient; placing the defibrillator in a pause state by actuating a pause actuator; and ending the pause state to provide therapy to the patient.
