  • METHODS, SYSTEMS, AND APPARATUS FOR SIMULATING THE CHANGE OF CHEST IMPEDANCE WITH PASSIVE COMPONENTS AND ELECTROCARDIOGRAM CONTAMINATION
    Publication number: 20230255537
    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.

  • Method of detecting when electrode pads have been handled or removed from their package
    Patent number: 7489972
    Abstract: Handling or removal of a pair of pre-connected defibrillator electrode pads from their package, or a compartment in the defibrillator, is detected in order to effectively time the issuance of prompts to guide the user. Detection occurs when an impedance level between the electrode pads varies sufficiently over time to indicate occurrence of the handling or removal event. The pads are preferably configured to leverage variability in the impedance that results from bending of pads during handling or removal.
