There is nothing like the HeartSine Samaritan 500P public access defibrillator with CPR advisor technology. HeartSine Samaritan 500P Defibrillator contains technology that determines whether your compressions are effective, electrically through the defibrillation pads.
Not only will voice prompts guide you through the process of defibrillation, but this device will tell you to “Push Harder” or whether you are doing “Good Compressions” during CPR – all based on real cardiac output (real blood flow).
