Abstract: A heart rate monitor (40) for detecting a pulse of a person (10) employs a platform (43), a plurality of multi-axis accelerometers (41R, 41L) and a pulse detector (44). The multi-axis accelerometers (41R, 41L) are adjoined to the platform (43) to generate differential mode signals (AZR, AZL) indicative of a sensing by the accelerometers (41) of physiological motion (12) of the person (10) relative to acceleration sensing axes (42R, 42L) and to generate common mode signals (AXR, AXL, AYR, AYL) indicative of a sensing by the accelerometers (41R, 41L) of extraneous motion by the person (10) relative to the acceleration sensing axes (42R, 42L). The pulse detector (44) is operably connected to the multi-axis accelerometers (41R, 41L) to generate a pulse signal (PS)as a function of a vertical alignment of the acceleration sensing axes (42R, 42L) combining the differential mode signals (AZR, AZL) and cancelling the common mode signals (AXR, AXL, AYR, AYL).

Abstract: A defibrillator (AED) and method for using a defibrillator 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: An electromechanical system for generating a CPR-corrupted ECG signal is provided. The electromechanical system may include an ECG signal generator electrically coupled to a first contact of an AED. The electromechanical system may further include a potentiometer electrically coupled to the ECG signal generator and a second contact of the AED. The electromechanical system may further include a compression mechanism. The compression mechanism may be configured to receive a vertical force and adjust an impedance of the potentiometer according to the vertical force. The compression mechanism may include a rack having a plurality of teeth and an initial position. The rack may be configured to translate to a second position according to the vertical force. The compression mechanism may further include a gear with a plurality of teeth engaged with the teeth of the rack such that the gear rotates according to the translation of the rack.

Abstract: An apparatus and method provides improved guidance instructions to providers of cardiopulmonary resuscitation (CPR) compressions in a cardiac arrest event. The apparatus detects CPR rate and/or changes in CPR rate, and issues prompts related to checking the depth of compressions based upon the rate/rate change detection. The prompts may be aural or visual.

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 (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 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 refibriUation, 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.
