Abstract: In an embodiment, a medical device can be used with a power adapter system. In addition, it can receive a data set from the power adapter system, and examine the data set to determine whether the data set confirms or not an authentication of the power adapter for use with the medical device. If the authentication is not confirmed, the external medical device can operate differently than otherwise. For example, power can be drawn more slowly from the power adapter system.

Abstract: The invention includes a very fast voice coil actuator, in the range of 2-5 millisecond full stroke response with high force, a circuit board located in the enclosure, a pressure sensor sensing pressure internal to the system which in the preferred embodiment is located in the actuator cap assembly but could be located in other locations, a diaphragm, a link plate, a mating ring, and a mechanical pressure regulator.

Abstract: Devices, methods, and software implementing those methods for providing communicating external chest compression (ECC) devices and defibrillation (DF) devices, where the ECC and DF devices can be physically separate from each other. Both ECC and DF devices are able to operate autonomously, yet able to communicate with and cooperate with another device when present. Some ECC and DF devices are adapted to be physically and/or electrically coupled to each other. One ECC device includes a backboard, a chest compression member, a communication module, controller, and at least one sensor, electrode lead or electrode. One DF device includes a defibrillator module, a controller, and a communication module that can communicate with the ECC communication module. The communicating ECC and DF devices may deliver ECC, pacing, defibrillation, ventilation, and cooling therapies, and may deliver instructions to human assistants, in a coordinated and cooperative fashion.

Abstract: An electrically non-conductive back plate for supporting the back of a patient in a supine position comprises on its front face facing the back of the patient a pair or more of ECG electrodes capable of maintaining electrically conductive skin contact with the patient's back. The pair of ECG electrodes is disposed at a sharp angle with the mean heart vector, in particular so as to form an angle ? of about 45°±25° with the projection S of the patient's spine on the back plate. Also disclosed is an ECG electrode for mounting in a recess of the back plate and an apparatus for treating cardiac arrest by compression of the sternum comprising the back plate.

Abstract: Defibrillators, software and methods are provided, for issued verbal prompts to rescuers. A defibrillator may receive a muting input and, responsive thereto, cause a verbal prompt to not be issued or to be issued less loudly relative another verbal prompt.
