Infant/Child Training Electrode Pads Cartridges are available for training and demonstration purposes. These non-clinical electrode pads, when installed in the HeartStart OnSite, suspend the defibrillator's ability to deliver a shock and activate its training mode, enabling the user to run any of eight emergency scenarios. The defibrillator's voice instructions include cardiopulmonary resuscitation (CPR) coaching. A training electrode pads cartridge can also be used on a manikin, with the aid of External Manikin Adapter (M5089A).
