    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.

    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.

    IPC: A61H31/00

    Abstract: A cardiopulmonary resuscitation (“CPR”) device that includes a chest compression mechanism, a support structure, and a plurality of inflatable support pads. The chest compression mechanism is configured to deliver CPR chest compressions to a patient. The support structure includes a base member configured to be placed underneath a patient, and a leg configured to support the chest compression mechanism at a distance from the base member. The plurality of inflatable support pads are configured to provide lateral support to a patient's chest during use of the CPR device. Each support pad within the plurality of support pads includes a holder configured to retain and at least partially surround the adjacent support pad.

    Abstract: Systems, apparatuses, and methods directed to the collection and analysis of data related to a patient during an emergency advanced airway management process. The collected data may be obtained using various types of sensors, with the data collection process being managed or coordinated by a suitable system, such as a combination monitor-defibrillator. The monitor-defibrillator (alone or in combination with other system elements, such as a wired or wireless communications capability, a processor, data storage, etc.) may include a capability to process some or all of the acquired data, and in response indicate to a user when some of the collected data may be unreliable.

    Abstract: Embodiments of the present invention are related to a method and device for the determination and calculation of the depth of chest compressions during the administration of cardiopulmonary resuscitation (CPR). Embodiments use an optical sensor to monitor the distance that a victim's chest is displaced during each compression throughout the administration of CPR. The optical sensor is most commonly an image sensor such as a CMOS or CCD sensor, and more specifically a CMOS image sensor capable of three-dimensional imaging based on the time-of-flight principle. An infrared emitter may illuminate the victim's body and any visible piece of ground beside the victim. As the infrared light interacts with any surfaces it encounters, it is reflected and returns to the image sensor where the time of flight of the infrared light is calculated for every pixel in the image sensor. The distance data is used to gauge the effective displacement of the victim's chest. The optical sensors can be used to visualize the size of a patient and immediately gauge the body type and instruct the user accordingly. Furthermore, optical measurement techniques can be used to accurately measure chest rise during artificial respiration and ensure that proper ventilation is being administered in between compressions. In addition, optical measurements of the chest of the victim and the hands of the rescuer can be used to help ensure that the rescuer has positioned his or her hands in the anatomically correct location for effective CPR.
