The Cardiac Science Powerheart G5 Adult Defibrillation Pads are stored preconnected to the AED to expedite the rescue process. 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.
