This is a Zoll CPR-D-padz accessory kit that contains CPR barrier mask, scissors, gloves, prep razor, towel and a moist towelette in a small zip-lock pouch. It is meant to be used in conjunction with the Zoll CPR-D Padz.
This accessory kit is included in your AED Plus Defibrillator original purchase. These are disposable kits used one per rescue. Extra kits really come in handy and should be kept on-hand for additional rescues.
