Analyze option button for an automated external defibrillator (aed) with dual ecg analysis algorithms

An automated external defibrillator (AED) for use during cardiopulmonary resuscitation (CPR) comprising:

• a user interface having at least one of an aural instruction output and a visual display;
• a user input button;
• an input of an ECG signal;
• a shock delivery circuit;
• a computer memory for storing instructions related to
• a first ECG analysis algorithm that is operable to determine a shockable cardiac rhythm from the ECG signal in the presence of a CPR-related signal noise artifact from the input, and
• a CPR rescue protocol that includes at least one period for providing CPR compressions and another period for abstaining from CPR compressions;
• a controller disposed in controlling communication with the user interface, the user input, the ECG signal input, the computer memory and the shock delivery circuit,
• wherein the controller is further operable to set an operating state of the defibrillator responsive to both of a sensed actuation of the input button during the one period and the analyzed ECG signal.
