  • Patent number: 11850439
    Abstract: A medical device that includes a power source, a therapy delivery interface, therapy electrodes, electrocardiogram (ECG) sensing electrodes to sense ECG signal of a heart of a patient, a sensor interface to receive and digitize the ECG signal, and a processor. The processor is configured to analyze the ECG signal to determine a cardiac rhythm and a transform value representing a magnitude of a frequency component of the cardiac rhythm, analyze the cardiac rhythm and the transform value to detect a shockable cardiac arrhythmia by classifying the cardiac rhythm as a noise rhythm or a shockable cardiac arrhythmia rhythm based on the transform value, and causing the processor to detect the cardiac arrhythmia if classifying the cardiac rhythm as a shockable cardiac arrhythmia rhythm, initiate a treatment alarm sequence, adjust the shock delivery parameter for a defibrillation shock, and provide the defibrillation shock via the therapy electrodes.

  • Patent number: 11801393
    Abstract: This document presents a system for managing treatment for an emergency cardiac event. The system includes memory, one or more electronic ports for receiving ECG signals, and a treatment module executable on one or more processing devices. The module is configured to generate transform values for a time segment of ECG, obtain one or more previous values derived from one or more earlier time segments of the ECG, and determine, based on the generated transform values, and the one or more previous values, at least one of: a) a future therapeutic action for treating the emergency cardiac event, or b) a phase of the cardiac event. The module is further configured to cause one or more output devices to present an indication of at least one of the therapeutic action or the phase of the cardiac event.

  • Publication number: 20220328182
    Abstract: A computer-implemented method for providing summary information for lifesaving activities is disclosed. The method involves sensing one or more activities that are repeatedly and cyclically performed on a victim by a rescuer; identifying a cyclical timing interval over which performance is to be analyzed for a integer number of cycles of the one or more activities, and gathering data from the sensing of the one or more activities during the time interval; generating, from analysis of the one or more activities, summary data that condenses data sensed for the one or more activities into a summary of the one or more activities; and providing, for display to a user, a visual summary of the performance of the one or more activities over the identified time interval.

  • Publication number: 20220280378
    Abstract: A system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient. In one aspect, a system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient includes a sensor for determining a parameter of the patient (e.g., indicative of a blood flow or pressure waveform), and one or more processors configured for receiving input from the sensor, determining, based on the input from the sensor, whether a rate of chest compressions administered in the CPR treatment should be changed, and providing an indication to a user that the rate of chest compressions should be changed.
