  • Patent number: 12369796
    Abstract: An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

  • Publication number: 20250152466
    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: 20250152097
    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.

  • Publication number: 20250152465
    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.

  • Publication number: 20250152463
    Abstract: A medical device uses UWB units to infer a position of an adjunct positioned in proximity to an exterior portion of a patient's body. The position information can be used to provide CPR feedback to a rescuer. In other applications, the position information can be used to provide prompts to a user to change the position of the adjunct.

  • Publication number: 20250009227
    Abstract: A remote patient monitoring system having a main patient monitor and a remote patient monitor. The main patient monitor is configured to receive and collect one or more patient physiological parameters and to provide an alarm in response to an alarm trigger. The alarm trigger includes a determination that at least one of the collected patient physiological parameters has reached a predetermined value. The remote patient monitor has an alarm reset and is configured to be carried by a caregiver. It is also configured to receive a signal from the main patient monitor in response to the alarm and to transmit an indication about the alarm trigger. The indication includes one or more of a notification that the patient is being attended to, a request by the caregiver for additional help, or a message about resolution of the alarm trigger.

  • Publication number: 20240341656
    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.

  • Patent number: 12102301
    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.

  • Patent number: 12089985
    Abstract: The disclosed non-invasive blood pressure systems and methods measure a patient's blood pressure without restricting blood flow. Other sensors, such as physiological sensors, sensors that sense data about the NIBP system components, and/or environment sensors sense data that is combined with the NIBP signal. The combined NIBP and sensor signals are used to measure a patient's non-invasive blood pressure.

  • Publication number: 20240298999
    Abstract: Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.

  • Publication number: 20240261179
    Abstract: Systems, devices, and methods for determining a condition of a subject during cardiopulmonary resuscitation (CPR) are described herein. In an example method, a measurement of a physiological parameter of an individual is filtered and/or gated based on identifying a treatment administered to the individual. A condition of the subject is identified based on filtering and/or gating the physiological parameter. The example method can be implemented into a mechanical chest compression device or another portable medical device. Together, the methods can improve the monitoring and treatment of subjects receiving CPR.
