You don't need to purchase a seperate set of pediatric pads every two years with the Philips FRx AED. When the Philips Heartstart® FRx® Infant / Child Key is inserted into the AED, it reduces the energy and allows you to use the adult pads on pediatric patients. This makes the Philips FRx very cost effective to own over a long period of time. The key can be used an unlimited amount of times and never needs to be replaced.
