Defi6 is a portable automatic external defibrillator (AED) that is lightweight, easy to use, and guides the user through the defibrillation process. It analyzes the patient's heart rhythm and will either prompt the user to deliver a shock if needed or begin CPR instructions. The AED is designed to be used in situations where emergency responders may be several minutes away. It uses adhesive pads to deliver the shock and has features like voice prompts, ECG analysis, and event recording for reporting.
