  • Patent number: 10702449
    Abstract: A CPR chest compression machine includes a retention structure that is configured to retain a body of the patient, and a compression mechanism. The compression mechanism is coupled to the retention structure and configured to perform successive compressions to the patient's chest. Various types of chest compressions may be performed on a patient during a single resuscitation event. Some embodiments also include a driver configured to drive the compression mechanism. The compression mechanism may thus perform chest compressions that differ from each other in a number of aspects, for example the depth of the compressions or the height of the active decompressions between the compressions. Some embodiments also include an adjustment mechanism. The adjustment mechanism may shift the compression mechanism with respect to the patient so that the chest compressions are performed at different locations of the patient's chest.

  • Patent number: 10625088
    Abstract: A defibrillation device for administering an electrotherapy, such as a dual-sequential defibrillation (DSD) electrotherapy. The defibrillation device can include a defibrillation therapy module, a physiological parameter module and a control module. The defibrillation therapy module can output one or more energies and the physiological parameter module can receive one or more physiological parameters, including electrocardiogram (ECG) data. The control module can analyze the physiological parameters to determine an indication for the administration of an electrotherapy and can determine a DSD electrotherapy. The DSD electrotherapy can be based at least in part on the physiological parameters, the indication for the administration of an electrotherapy or a review of the ECG data.

  • Patent number: 10504618
    Abstract: Techniques for routing event data from a field device, such as an external defibrillator, to a selected subset of a plurality of possible destinations are described. The event data may include physiological data of the patient, such as a 12-lead electrocardiogram (ECG). The destinations may be associated with one of a plurality of patient treatment centers, and may include, as examples, computing device, printers, displays, personal digital assistants, or web-accessible accounts. In some examples, a server maintains user-configurable information or rules for at least some of the destinations, and uses the information or rules for determining whether event data received from a field device is routed to the destination. In some examples, the server may also make the routing determination based on an analysis of event data, such as a determination as to whether the event data indicates that the patient is suspected to be experiencing an acute myocardial infarction.

  • Patent number: 10490308
    Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received that may be derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. Then a figure of merit (FOM) can be computed from the data. In the computation, at least one pause can contribute a penalty to the FOM. The penalty has a value determined from at least one control factor, other than a constant linear dependence on the duration of the pause. This way, pauses can incur penalties to the FOM computation depending on their context, instead of merely their duration. For example, a penalty can escalate non-linearly if its pause becomes unduly long, or if it follows a set of chest compressions that was unduly short. As such, a better CPR quality assessment is achieved.

  • Patent number: 10420702
    Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received, derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. In some embodiments, a penalty value can be determined for at least one of the pauses, from at least one control factor unrelated to a constant linear dependence on the pause duration. An indicative value can be derived from the penalty value. In some embodiments, at least some of the pauses are classified in one or more pause groups, depending on how well they meet one or more classification criteria. The indicative value can be derived for one of the pause groups. The indicative value can be output, and/or an alarm can be emitted if it exceeds a threshold. CPR quality assessment can be improved in real time, and provide feedback for training.
