If you observe someone who may be suffering from sudden cardiac arrest, the best thing to do is act quickly. The Philips HeartStart M5068A Home Defibrillator has been equipped with integrated SMART pads. All you have to do is place the SMART Pads on the bare chest of the person’s skin and it will provide information to the AED so the voice instructions can adapt to your actions and pace. The SMART pads are able to sense when they are on the patient and know when you have completed each step. The Home AED won’t advance you to the next step until everything is ready. The voice prompts will be repeated, even rephrased and will include additional instructions to help you understand what needs to be done next.
