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.

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.

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.

Abstract: Various techniques related to post-treatment parameters of patients are described. An example method includes identifying a segment of an electrocardiogram (ECG) of an individual, wherein the segment is detected during a time interval that begins when an electrical shock is output to the individual's heart. The method further includes identifying a parameter of the electrical shock and generating a report including the segment of the ECG and indicating the parameter of the electrical shock. The report is output or transmitted to an external device.

Abstract: An electrode assembly that is adjustable in size, as well as systems, and methods of use thereof are described. The electrode assembly includes multiple electrode portions including at least a first electrode portion and a second electrode portion, the second electrode portion disposed on the first electrode portion at an edge of the first electrode portion, wherein the second electrode portion has a cutout, and wherein the first electrode portion spans the cutout. The electrode assembly is configured to be used with a medical device, such as an external defibrillator. A process of automatically selecting a usage mode of a medical device based on detecting which electrode portion(s) has been removed from an electrode storage tray is also described.

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.

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.

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.
