  • Alerting users of CPR feedback device of detected magnetic interference
    Patent number: 10098573
    Abstract: A medical device and/or a method are used by a rescuer who is caring for a patient. The depth of CPR chest compressions is determined, by detecting magnetic fields. An interference is sensed, which is not associated with the CPR chest compressions, but which is superimposed on the detected magnetic fields. Appropriate countermeasures may be taken, if the sensed interference is larger than a threshold.
    Type: Grant

    Date of Patent: October 16, 2018
    Assignee: PHYSIO-CONTROL, INC.
    Inventors: Isabelle L. Banville, Robert Peter Marx, Jr., David Thomas Brown, Richard C. Nova
