The Cardiac Science Powerheart G5 Fully-Automatic AED featuring dual language (English-Spanish) technology is an effective and highly popular package to have on hand. This AED is designed for use by individuals of all skill levels ranging from professional use to lay responder. The Rescue CoachTM technology will carefully guide the rescuer through each step of a rescue as well as provide step-by-step instructions to perform effective CPR. The G5 AED uses user-paced prompts to ensure any responder can successfully deploy the AED. For responders with MORE experience, the AED will skip all unnecessary prompts, and for LESS experienced responders, the AED will repeat prompts until the responder completes the previous step. With industry leading Variable-Escalating Energy technology, the G5 AED can deliver patient-specific therapy at a point of rescue, leading to a higher success rate for defibrillation during an emergency.
