Cardiac Science Powerheart® G5 Adult Intellisense™ CPR Feedback (ICPR) Defibrillation Electrode Pads. Performing effective CPR is crucial during a cardiac emergency and often leads rescuers to wonder, "Am I doing CPR properly?" With Intellisense CPR Feedback, providing effective CPR compressions is now within reach. Thanks to a compact design, Intellisense CPR Feedback may be used on patients of all chest sizes. Motion sensor technology – the same technology used on most smart phones – provides rescuers with immediate voice prompts if their CPR compression rate and depth are outside the 2015 AHA-acceptable parameters.* The easy-to-use, intelligent CPR device works in combination with your Powerheart® G5 automated external defibrillator to deliver potentially life-saving CPR and defibrillator therapy.
