  • Patent number: 12161442
    Abstract: According to an aspect, a method for determining an augmented vital sign, such as heart rate or heart rate variability, includes obtaining signals from a patient when the patient is both active and inactive. An activity signal is generated from the first signal, and a physiological signal is generated from the second signal. An activity weight factor is calculated from the activity signal, and a vital sign signal is calculated from the physiological signal. A mapping from the activity signal to the vital sign aids the determination of the vital sign through a motion period. The augmented vital sign is a result of the combination of first and second values, including the product of the activity weight factor and an activity derived vital sign, and the product of the vital sign signal and the activity weight factor less than one.

  • Publication number: 20240347198
    Abstract: In some examples, a computing system tracks, across a plurality of predictions, prediction performance of a first oxygen saturation prediction model used by one or more patient monitoring devices by comparing a respective prediction made by the first oxygen saturation prediction model to a corresponding ground truth. The computing system determines whether the prediction performance of the first oxygen saturation prediction model meets a performance metric, wherein the performance metric includes an accuracy level, a specificity level, a sensitivity level, or any combination thereof. The computing system may, in response to determining that the prediction performance of the first oxygen saturation prediction model does not meet the performance metric, cause the one or more patient monitoring devices to switch to a second oxygen saturation prediction model to predict future oxygen saturation levels of one or more patients.

    Abstract: A system for monitoring autoregulation may include processing circuitry configured to receive a blood pressure signal indicative of an acquisition blood pressure of a patient at an acquisition site and an oxygen saturation signal indicative of an oxygen saturation of the patient. The processing circuitry may determine an altered blood pressure value indicative of a reference blood pressure of the patient at a reference site based on the blood pressure signal. The altered blood pressure value may enable a more accurate subsequent determination of a value indicative of the autoregulation status of the patient compared to an unaltered blood pressure value. In some examples, the processing circuitry may provide a signal indicative of the autoregulation status of the patient to an output device to enable a clinician to monitor the autoregulation status of the patient.
