The Lifeline AUTO has all the same features as the Lifeline AED; with the difference being that the shock is delivered automatically without the need to press the shock button. This takes away the fear of the rescuer to use the defibrillator. Lifeline AUTO automatically detects when defibrillation is required, ensuring treatment is only delivered when needed. The Lifeline AUTO is able to identify and treat Ventricular Fibrillation, Ventricular Tachycardia and Supraventricular Tachycardia. If you are a non-medical organization that is looking for a defibrillator that provides you with all the simplicity of use of the Lifeline AED but also removes the responsibility of having to press the button to deliver the shock then the Lifeline AUTO is the defibrillator for you.
