The Philips HeartStart OnSite Infant/Child Training Pad Cartridge can be used on the HeartStart OnSite Trainer or the HeartStart OnSite AED to train students. When placed on the real HeartStart OnSite AED, the pads will convert the AED into a trainer, suspending its ability to shock. While the training cartridge is connected to either unit, 8 rescue scenarios are activated to give the user a hand-on experience of how a real rescue will feel. When the infant/child pads are connected, the voice prompts will be specific for pediatric use just as in a real rescue. The training pads cartridge consists of a removable clear protective lid with a handle, a resealable film cover, and a pair of reusable adhesive pads.
