    Abstract: The disclosed physiological feedback systems and methods assist with assessing, monitoring and/or treating a patient experiencing a cardiac arrest event. The systems and methods receive multiple inputs and are continuous and/or iterative during a treatment session to provide physiological state trends of the patient. An index of the physiological state of the patient can be derived and confounders, and/or their effects, can be identified, and/or removed, from the index. Additionally, the systems and methods can assist with determining ischemic injury in a patient based on cerebral tissue oxygenation and/or other physiological data.

    Abstract: Systems to retain a battery within, and to eject a battery from, a battery receptacle of a medical device, such as a portable defibrillator, are described. A battery receptacle of a medical device includes an element that is configured to engage an inserted battery to prevent, or reduce, movement of the battery within the receptacle and to assist with removing the battery from the receptacle. In an example, the element is a monolithic structure that includes a retention portion and an ejection portion. The retention portion is positioned at a side wall of the battery receptacle, and the ejection portion terminates in a free end positioned a distance from the side wall. When the battery is inserted into the battery receptacle, the retention portion exerts a retention force on a side surface of the battery, and the ejection portion exerts an ejection force on an end surface of the battery.

    Abstract: An example method of analyzing electrocardiogram (ECG) signals includes receiving, at an ECG device, ECG signals from a multi-lead ECG system. The multi-lead ECG system includes multiple electrodes and leads, and each lead of the multi-lead ECG system provides one of the ECG signals and is coupled to more than one of the multiple electrodes, where certain electrodes are coupled to more than one lead. The method also includes detecting artifact in one or more of the ECG signals, classifying the artifact as a type of artifact, determining which leads of the multiple leads contain at least a threshold amount of the type of artifact, for the leads of the multiple leads that contain at least the threshold amount of the type of artifact identifying a common electrode to the leads, and generating a notification by the ECG device indicating that the common electrode is sensing the artifact.

    IPC: A61B5/00

    Abstract: An example system for wireless monitoring of patient parameters and initiating mitigations based on quality of service (QoS) measurements includes a plurality of sensors connected to a patient, a therapy module, and a monitor module that executes instructions to receive the signals from the plurality of sensors over the wireless communication link, determine therapy commands for delivering therapy to the patient and send the therapy commands to the therapy module, based on the QoS measurement being below a threshold initiate a short-term mitigation that includes providing an alert and to determine a modification to the therapy commands, based on the QoS measurement continuing to remain below the threshold, subsequently initiate a long-term mitigation that includes employing a secondary communication technique between the plurality of sensors and the monitor module to replace the wireless communication link, and controlling the therapy module according to the therapy commands during the long-term mitigation.
