The Heart Sync multi-function pediatric defibrillator pads from Vermed are a step above the other pads on the market. These cost-effective pads are designed to be compatible with all Physio-Control LifePak defibrillators. The Heart Sync multi-function pediatric defibrillator pads will save you the cost and hassle of replacing your pads frequently because they have a 36 month shelf life. They also feature the longest lead wires available. The 60 inch wires will give you plenty of room for positioning equipment. Smaller pad sizes make it easier to position the pads correctly on young patients. These pads are intended for use with pediatric patients who weigh less than 55 pounds.
