Publication number: 20230381061Abstract: A CPR feedback system, software and methods are provided. A top height sensor can be used to track the height of the patient's chest during the CPR chest compressions, by detecting a top aspect of its location. A depth module may generate, from a detected top aspect, a depth value for a depth reached by a current compression. A counter may determine a compressions number, e.g. for the current compression. A memory may store a depth variable that can return different target values for the target depths of individual compressions. A user interface has an output device that may output an indication for the rescuer, which reflects how well the depth value of the current compression matched a corresponding target value for it. The target values may be set so as to follow a preset profile, or change according to optional measurements of force and other parameters.Type: ApplicationFiled: August 3, 2023Publication date: November 30, 2023Applicant: Physio-Control, Inc.Inventors: Fred William Chapman, Gary Debardi

Publication number: 20230264037Abstract: A wearable cardioverter defibrillator (“WCD”) system includes a support structure that can be worn by a patient, and a defibrillator coupled to the support structure. An ECG input, rendered from an ECG of the patient, may meet a primary shock criterion. One or more sensor modules are further provided, which are worn by the patient at different times. The sensor modules may monitor different physiological parameters of the patient, and transmit signals about them. The WCD system further has a multi-sensor interface to receive the transmitted signals, and a processor to determine from them whether a secondary shock criterion is met. If both the primary and the secondary shock criteria are met, the decision is to shock. The signals increase specificity of the detection, while the patient can wear different modules depending on context.Type: ApplicationFiled: April 27, 2023Publication date: August 24, 2023Applicant: West Affum Holdings DACInventors: Fred William Chapman, Gregory T.

Patent number: 10820833Abstract: A capnograph system may be used together with a ventilation system for a patient. The capnograph system may include a capnography module with a carbon dioxide detector, which may generate a carbon dioxide signal responsive to an amount of carbon dioxide detected within an air path of the ventilation system. A monitoring circuit may further detect a pressure within the air path. A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.Type: GrantFiled: December 8, 2017Date of Patent: November 3, 2020Assignee: PHYSIO-CONTROL, INC.Inventor: Fred William Chapman

Patent number: 8433407Abstract: An apparatus and method is provided for a defibrillator that specifies treatment protocols in terms of number of chest compressions instead of time intervals. The defibrillator includes a connection port that is configured to attach with a plurality of electrodes that are capable of delivery of a defibrillation shock and/or sensing one or more physical parameters. An energy storage device capable of storing a charge is attached to the plurality of electrodes. A controller is coupled to the plurality of electrodes and the energy storage device, the controller is configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.Type: GrantFiled: March 31, 2005Date of Patent: April 30, 2013Assignee: Physio-Control, Inc.Inventors: Fred William Chapman, Robert G.

Publication number: 20120022606Abstract: A system is disclosed wherein patient data, such as an electrocardiogram (“ECG”) signal or a chest impedance measurement signal, collected by a defibrillator device during a resuscitation event is analyzed and processed by a computing device to provide an assessment of CPR administered during the event. The CPR assessment results in one or more CPR figures of merit that relate to temporal characteristics of the CPR relative to the duration of the event. In one embodiment, the CPR figure of merit represents a percentage of the event period during which chest compressions were administered to the patient.Type: ApplicationFiled: September 30, 2011Publication date: January 26, 2012Applicant: PHYSIO-CONTROL, INC.Inventors: Robert G.

Patent number: 8090441Abstract: An external defibrillator is customized for at least one person, i.e., an anticipated patient, through creation of a profile for the anticipated patient that allows the defibrillator and users of the defibrillator to provide customized treatment to the patient. The profile may include treatment parameters for the anticipated patient, such as defibrillation therapy parameters selected for the patient. The profile may also include a baseline recording of a physiological parameter of the patient, and medical history and personal information regarding the patient. In some embodiments, the external defibrillator stores a profile for each of one or more anticipated patients within a memory. In other embodiments, a profile for an anticipated patient is stored within a medium associated with that anticipated patient. The medium may, for example, be a removable medium for external defibrillators.Type: GrantFiled: August 25, 2010Date of Patent: January 3, 2012Assignee: Physio Control, Inc.Inventors: Fred William Chapman, Richard C.
