  • Publication number: 20220193429
    Abstract: Systems, devices, and methods provide up-to-date defibrillation shock recommendations. In an example method, multiple segments of an electrocardiogram (ECG) of an individual are detected from an individual receiving chest compressions. The multiple segments are evaluated to determine whether the individual is exhibiting a shockable heart rhythm. A medical device outputs a recommendation indicating whether a defibrillation shock is advised based on the most recent determination of the individual's heart rhythm. For example, the medical device outputs an up-to-date recommendation on-demand in response to an input signal from a user. In some examples, the medical device updates the recommendation based on ongoing analysis of the ECG.

  • Publication number: 20220193431
    Abstract: Defibrillators with enhanced functionality during cardiopulmonary resuscitation (CPR) periods are described. The enhancements include predicting a length of a charging period of a capacitor of the medical device so that capacitor is shock charged at the end of the CPR period. The enhancements also include re-assessing an electrocardiogram (ECG) signal for continued presence of a shockable rhythm during the CPR period and before administration of a defibrillation shock. Together the enhancements can improve the timing and recommended administration of defibrillation therapy.

  • Publication number: 20220193434
    Abstract: Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.

  • Publication number: 20220193430
    Abstract: Defibrillators providing enhanced recommendations of whether to administer a defibrillation shock to patients are described. An example defibrillator determines an analysis factor, such as whether a patient has previously exhibited high-amplitude or “coarse” ventricular fibrillation (VF) during a particular time period. The defibrillator generates a shock index based on an electrocardiogram (ECG) of the patient and determines whether the patient is exhibiting a shockable rhythm by comparing the shock index to a threshold. The defibrillator generates the shock index and/or the threshold based on the analysis factor. The defibrillator outputs a recommendation based on the determination of whether the patient is exhibiting the shockable rhythm.

  • Publication number: 20220193433
    Abstract: Systems, devices, and methods for detecting and addressing irregular motion to improve defibrillation shock recommendations are described. In an example method performed by a medical device, an electrocardiogram (ECG) of an individual receiving chest compressions is detected. In addition, irregular motion of the individual is detected. If a magnitude of the irregular motion is greater than or equal to a threshold, a remedial action is performed. In some examples, the medical device refrains from generating a recommendation indicating whether the ECG includes a shockable rhythm and/or whether a defibrillation shock is recommended. In some instances, the medical device outputs the recommendation with a certainty of the recommendation. In some cases, the medical device outputs a warning and generates the recommendation in response to receiving an input signal indicating a manual override.

  • Publication number: 20220062099
    Abstract: A mechanical CPR device having one or more of a piston, a driving component configured to extend the piston toward a patient's torso and retract the piston away from the patient's torso, a controller configured to control the driving component to at least compress the patient's torso by extending the piston from a reference position to a depth and retracting the piston from the depth to the reference position, and a contact member such as one or more of a pressure pad and a suction cup attached to the end of the piston. The contact member can include a semi-adhesive material that has low adhesiveness when the controller controls the driving component to compress the patient's torso less than 60 times per minute and high adhesiveness when the controller controls the driving component to compress the patient's torso more than 60 times per minute.

  • Publication number: 20220054000
    Abstract: Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.

  • Publication number: 20210244351
    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.

  • Patent number: 10981014
    Abstract: Dual sequential defibrillation (DSD) systems and methods include the use of a timing device. The timing device can assist a user with DSD administration by providing notifications spaced apart by the inter-shock timing. The user can use these notifications to trigger the administration of defibrillation in a sequential manner. The timing device can also be coupled to two defibrillation devices and can output a signal to each of the defibrillation devices to cause the defibrillation device to administer a defibrillation. The output of the signals by the timing device can be spaced apart by the inter-shock timing. Additionally, the signals can be QRS-like in nature to cause the defibrillation devices to administer a defibrillation when in a sync mode.

  • 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: 10835450
    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.
