Abstract

A defibrillator is provided with two processors for enhancing the defibrillation process. A first processor is dedicated to controlling when an electrical charge is applied to a patient. A second processor is dedicated to data operations for enhancing the coaching of the defibrillation process. The second data processor is in communication with one or more external devices for transmission and receipt of network data for further enhancing the coaching process. The second data processor allows both the defibrillator to be maintained with updated network data and software and the one or more external devices to be maintained with updated defibrillator data. Independent controllers provide multiple processing paths on critical charge and coaching functions; with the second data processor further providing redundancy control in the event of any malfunction of the first charge processor.
