Patent number: 11273314Abstract: 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 offers guidance throughout a cardiac rescue protocol involving both defibrillation shocks and CPR 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.Type: GrantFiled: May 16, 2019Date of Patent: March 15, 2022Assignee: Koninklijke Philips N.V.Inventors: Stacy Earl Gehman, James Knox Russell, Christopher William Fleming, Dawn Blilie Jorgenson, David Roy Axness

Patent number: 11197631Abstract: 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.Type: GrantFiled: January 8, 2020Date of Patent: December 14, 2021Assignee: Koninklijke Philips N.V.Inventors: Chenguang Liu, Stacy Earl Gehman, James Knox Russell, Christopher William Fleming, Dawn Blilie Jorgenson, David Roy Axness, Jeffrey Martin Boschee

Patent number: 10772516Abstract: 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).Type: GrantFiled: December 10, 2014Date of Patent: September 15, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: James Knox Russell, Haris Duric, Chenguang Liu

Patent number: 10583305Abstract: 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.Type: GrantFiled: May 23, 2016Date of Patent: March 10, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Chenguang Liu, James Knox Russell, Dawn Blilie Jorgenson, Haris Duric, Stacy Earl Gehman, Christopher William Fleming

Publication number: 20080234565Abstract: An ambulatory physiological monitor (10) is provided. The monitor includes at least one sensor for detecting at least one physiological parameter of a patient and a housing (42) adapted to be secured to the patient. A circuit (50) is located in the housing for receiving and processing a signal representative of the physiological parameter from the sensor to generate recordable physiological data and for determining if the data exceeds a preestablished alarm limit. An event indicator (12) is coupled to the housing for notifying the patient when the alarm limit has been exceeded. A wireless transmitter (28), operationally coupled to the circuit, is located in the housing for transmitting an emergency notification when the alarm limit has been exceeded. A patient-operable actuator (22) is coupled to the housing for preventing transmission of the emergency notification by the wireless transmitter upon activation by the patient within a predetermined time after the alarm limit has been exceeded.Type: ApplicationFiled: February 1, 2005Publication date: September 25, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: James Knox Russell, Thomas Dean Lyster
