Training responders to handle cardiac arrest emergencies just got easier with the Philips HeartStart OnSite Adult Training pads Cartridge. These training electrodes connect directly to the HeartStart OnSite Defibrillator or HeartStart Trainer. The training pads cartridge can also be used on a Manikin with the aid of an Internal Manikin Adapter or an External Manikin Adapter. Adult Training pads Cartridges are available for training and demonstration purposes. These special non-clinical pads, when installed in the HeartStart HS1 Defibrillator, 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 AED's voice instructions include cardiopulmonary resuscitation (CPR) coaching.
