Adult Intellisense® defibrillation pads are stored preconnected to the AED; a technology originally developed by Cardiac Science 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 St John G3 Elite defibrillator.
