Abstract: An automated external defibrillator (AED) is described which includes two electrocardiogram (ECG) analyzers. One of the ECG analyzers is suitable for use only for ECG which is signal-noise-free, and thus may be used during “hands-off” analysis periods in which no cardiopulmonary resuscitation (CPR) compressions can be provided. The length of the “hands-off” analysis period can be shortened by use of the second ECG analyzer in concert with the first ECG analyzer. Thus, a greater proportion of CPR time through the course of a cardiac arrest rescue is achieved.

Abstract: A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method offers guidance throughout a cardiac rescue protocol involving both defibrillation shocks and CPR that improves the effectiveness of the rescue, resulting in more CPR “hands-on” time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Abstract: A method and associated apparatus (12) detects the presence and quality of chest compressions during cardiopulmonary resuscitation (CPR) by analyzing existing signals in automated external defibrillator (AED) devices without using a stand-alone CPR meter. The method includes analyzing both a thoracic impedance signal and a common-mode current signal, each of which can be measured with standard AED pads (18). The method applies criteria to the measured signals, the criteria being used to select which of the measured signals to use for providing CPR chest compression detections.

Abstract: A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method includes a confidence analyzer circuit which determines the confidence level of an electrotherapy shock decision based on the detection. If the confidence level is low, the apparatus adjusts its shock decision criteria.

Abstract: A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method provides both of a continuous and scheduled mode of operation for interleaving periods of CPR with electrotherapy, in a manner that improves the effectiveness of the rescue, resulting in more CPR “hands-on” time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Abstract: A defibrillator (AED) using two different ECG analysis algorithms which work sequentially to improve the accuracy of AED shock decisions. A first algorithm, such as (ART), is particularly suited for analysis in the presence of CPR periods. A second algorithm, such as (PAS), is particularly suited for analysis during hands-off periods. The AED switches algorithms depending on the period and on the current analysis of the cardiac rhythm. The inventions thus provide an optimized ECG analysis scheme in a manner that improves the effectiveness of the rescue, resulting in more CPR “hands-on” time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Abstract: A method (100) for using an automated external defibrillator (AED) (310), the method comprising: receiving (120), during an active CPR protocol, a signal indicative of motion or lack of motion of the individual; analyzing (130), by the controller, the received signal to determine whether the individual is undergoing motion; providing (140) a direction to begin or continue chest compressions if the controller determines from the received signal that the individual is not undergoing motion; analyzing (150), by the controller, a received ECG signal to determine whether the individual could benefit from a shock delivered from the AED; interrupting (160) the active CPR protocol, if the individual is not undergoing motion and if the individual could benefit from a shock delivered from the AED; and delivering (170) a shock to the individual.

Abstract: A defibrillator (AED) using an ECG analysis model or algorithm which can function in two different modes. The ECG analysis model is particularly suited for analysis during periods of CPR. Both modes of operation reach a shock decision in essentially the same way, where one or more ECG data segments indicate a shockable cardiac condition. In one mode of operation, the shock decision is irreversible once made. In another mode of operation, the shock decision is reversible if one or more subsequent ECG data segments indicate a no-shock decision. Improved specificity of the model is obtained without undue degradation of sensitivity to shockable ECG.

Abstract: A defibrillator (AED) and method for using a defibrillator incorporates a user activated button which truncates an ongoing ECG analysis to immediately perform a different defibrillator-related function. For example, the AED may use two different ECG analysis algorithms having different sensitivities to a shockable cardiac rhythm, and a press of the button may automatically shift from a first algorithm to a second algorithm with the higher sensitivity. The button may also allow truncation of ongoing analysis and CPR for immediate preparation for electrotherapy.
