More Information
Summary:This invention relates generally to defibrillators, and more specifically to portable, automated external defibrillators having a user interface for automatically providing an untrained rescuer with visual and aural instructions for performing emergency cardiopulmonary resuscitation and defibrillation therapy. An automated external defibrillator (AED) () designed for use by a rescuer with minimal or no training during a medical emergency is provided. The AED implements a user interface program () which guides the rescuer through operation of the AED and application of CPR and defibrillation therapy to a patient by displaying a series of visual instructions on a graphic display () or other visual output device, and by providing additional aural instructions via a speaker () or other aural output device. The rescuer merely needs to press a start button () to initiate operation of the AED and begin CPR and defibrillation instruction.
