  • Publication number: 20210045655
    Abstract: 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.

  • Patent number: 10905344
    Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

  • Publication number: 20210000684
    Abstract: In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system also includes a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. An advantage can be when the attendant checks in situations where the condition of the patient might have changed, and an adjustment is needed. Or in situations where the patient may have improved enough to where the compressions are no longer needed.

  • Publication number: 20200330325
    Abstract: A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is varied based on feedback gathered from physiological sensors that detect physiological characteristics of the patient during treatment.

    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: 10792215
    Abstract: A mechanism attached to a mechanical CPR device can be automatically attached to the patient's torso. The mechanical CPR device can extend the mechanism to a first position at which the mechanism comes into contact with the patient's torso. The mechanism can be further extended until a first threshold is reached. The mechanism can be retracted to the first position. The mechanism can be further retracted from the first position until a second threshold is exceeded. The mechanism can then be extended to a second point at which the second threshold is no longer exceeded. The mechanism may comprise a suction cup or sticker plate, and may be attached to an end of a piston of the mechanical CPR device.

  • Publication number: 20200306133
    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.
