Adult Intellisense defibrillation pads are stored pre-connected to the AED. The pads can be placed in either position on the chest to reduce confusion and save time during a rescue. Using patented Rescue Ready® technology and embedded circuitry, Intellisense defibrillation pads communicate presence, functionality, patient type, energy and CPR protocol, pad expiration, and other vital information directly to your Powerheart G5. The electrode pads have a 2-year shelf life.
