ZOLL Pedi-Padz II Electrodes are designed for use on children up to eight years of age or weighing less than 55 pounds/25 kg. Anatomical diagrams on the package indicate proper placement and will generate an alert to confirm pediatric pads are being utilized when connected to the ZOLL AED Plus or ZOLL AED Pro. Separate and specific algorithms designed for children are used to provide pediatric-specific therapy with reduced energy.
