To facilitate training on the OnSite Defibrillator, Philips Infant/Child (M5074A) Training Pads Cartridges are available. These special purpose cartridge 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, including cardiopulmonary resuscitation (CPR) coaching, are appropriate for teaching how to treat an Infant/Child – the simulated victim.
