For use exclusively with the ZOLL AED 3?, CPR Uni-padz electrodes have an industry-leading shelf life of five years and can be used on both adult and child patients, so there is no need to maintain two separate sets of pads. The ZOLL AED 3 full-colour LCD display includes graphics that coincide with the electrode shapes and colours to support proper pad placement on both adults and children. By simply repositioning the pads and activating the Child Mode on the ZOLL AED 3, CPR Uni-padz can be used to treat child patients 8 years of age or younger or under 25 kg (55 lbs.).
