The G5 is a great device and one of the newest on the market. One thing that makes it unique is its ability to shock in under 10 seconds, which few devices can claim to do. It also comes with proprietary technology like Adult Intellisense® CPR Feedback, also known as ICPR, Defibrillation Electrode Pads with CPR Device available. It comes pre-attached to the Adult Defibrillation Pads and is automatically recognized and synchronized with the G5. It offers clear, concise instructions and feedback in real-time on chest compression rate and depth. These are great features to have for a lay rescuer who has never had to use an AED or do CPR before.
