Patent number: 8160703Abstract: Signal data obtained from a piezoelectric sensor placed on a patient's body is used to detect the presence of a cardiac pulse. The piezoelectric sensor has a transducing element adapted to sense movement due to a cardiac pulse and produce piezoelectric signal data in response thereto. Processing circuitry analyzes the piezoelectric signal data for a feature indicative of a cardiac pulse and determines whether a cardiac pulse is present in the patient based on the feature. In one aspect, the feature may be a temporal feature such as a relative change in energy. In another aspect, the feature may be a spectral feature such as the energy or frequency of a peak in the energy spectrum of the signal. In yet another aspect, the feature may be obtained by comparing the piezoelectric signal data with a previously-identified pattern known to predict the presence of a cardiac pulse. Multiple features may also be obtained from the piezoelectric signal data and classified to determine the presence of a cardiac pulse.Type: GrantFiled: July 22, 2005Date of Patent: April 17, 2012Assignee: Physio-Control, Inc.Inventors: Ronald E. Stickney, Cynthia P. Jayne, Paula Lank, Patricia O'Hearn, Tae H. Joo, David R. Hampton, Richard C. Nova, Patrick F. Kelly, William E. Saltzstein

Patent number: 8090437Abstract: A device tests a circuit that is a source of alternating current by measuring at least one electrical parameter of the circuit to determine whether the circuit is able to provide adequate energy for defibrillation by an external defibrillator. The device may test the circuit by applying a load to the circuit, and measuring one or more electrical parameters when the load is applied to the circuit. The device may be the external defibrillator itself, or a separate testing device. In some embodiments in which an external defibrillator tests a circuit, the defibrillator modifies a value of at least one therapy delivery parameter for a subsequent delivery of one or more defibrillation pulses based on the measured electrical parameter value measured. By modifying a therapy delivery parameter, the defibrillator may deliver defibrillation pulses at an energy level that is supportable by the circuit.Type: GrantFiled: April 8, 2010Date of Patent: January 3, 2012Assignee: Physio Control, Inc.Inventors: Joseph L.

Patent number: 7904152Abstract: A method of delivering electrical therapy to a patient by a medical device includes activating the medical device and performing a first analysis of a first set of data signals sensed by the medical device. If the first analysis shows the first set of data signals meets a first criterion, then charging of an energy delivery circuit is commenced upon completion of the first analysis. A second analysis of a second set of data signals from the patient is performed, and if the second analysis determines that the second set of data signals meet a second criterion, the therapy is delivered. The steps of performing the first analysis and performing the second analysis may be begun at substantially the same time. The step of charging may overlap in time with the step of performing a second analysis. The medical device may be an external defibrillator and the therapy may be a defibrillating shock.Type: GrantFiled: December 9, 2004Date of Patent: March 8, 2011Assignee: Physio-Control, Inc.Inventors: Joseph L.
