Abstract: In some examples, a device includes sensing circuitry configured to receive one or more signals from a patient and processing circuitry configured to determine a plurality of autoregulation state values associated with a plurality of blood pressure values based on the one or more signals. The processing circuitry is further configured to determine that a first autoregulation state value of the plurality of autoregulation state values is anomalous based on other autoregulation state values of the plurality of autoregulation state values. The processing circuitry is also configured to modify the first autoregulation state value in response to determining that the first autoregulation state value is anomalous and determine an autoregulation status of the patient based on the plurality of autoregulation state values including the modified first autoregulation state value.

Abstract: In some examples, devices, systems, and techniques are configured to compensate for changes in sensed blood pressure due to issues such as blood pressure sensor movement. For example, processing circuitry of a device may determine a difference value between a first blood pressure value representative of a blood pressure at a first time and a second blood pressure value representative of the blood pressure at a second time. Responsive to determining that the difference value is greater than or equal to a threshold value, the processing circuitry may generate updated blood pressure values by applying an offset value to the second blood pressure value and subsequently received blood pressure values that compensates for the difference value between the first blood pressure value and the second blood pressure value.

Abstract: A method for monitoring autoregulation includes, using a processor, receiving a blood pressure signal, a regional oxygen saturation signal, and a blood volume signal from a patient. The method also includes determining a first linear correlation between the blood pressure signal and the regional oxygen saturation signal and determining a second linear correlation between the blood pressure signal and the blood volume signal. The method also includes determining a confidence level associated with the first linear correlation based at least in part on the second linear correlation and providing a signal indicative of the patient's autoregulation status to an output device based on the linear correlation and the confidence level.

Abstract: A patient monitor for monitoring cerebral activity of a patient may include a processor configured to determine a depth of consciousness index for the patient based on electroencephalography (EEG) data and determine regional oxygen saturation for the patient based on regional oximetry data. Additionally, the processor may be configured to determine a metric associated with cerebral activity of the patient based at least in part on the one or more values of the depth of consciousness index and the one or more regional oxygen saturation values and to provide the one or more values of a depth of consciousness index and the metric to an output device.

Abstract: Methods and systems are presented for determining physiological information in a physiological monitor. A physiological signal (e.g., an EEG signal) received from a subject is wavelet transformed and first and second related features that vary in scale over time are identified in the transformed signal. First and second coupled ridges of the respective first and second related features may also be identified in the transformed signal. A non-stationary relationship parameter is determined and is indicative of the relationship between the first and second features and/or between the first and second ridges. Physiological information, which may be indicative of a level of awareness of a subject, is determined based on the non-stationary relationship parameter. This physiological information may be used, for example, in an operating room to monitor/regulate the subject's anesthetic state while under general anesthesia or in an intensive care unit to monitor the subject's sedateness and administer medication accordingly.

Abstract: The present technology relates to the field of medical monitoring, and, in particular, to non-contact detecting and monitoring of patient breathing. Systems, methods, and computer readable media are described for calculating a change in depth of a region of interest (ROI) on a patient. In some embodiments, the systems, methods, and/or computer readable media can identify steep changes in depths. For example, the systems, methods, and/or computer readable media can identify large, inaccurate changes in depths that can occur at edge regions of a patient. In these and other embodiments, the systems, methods, and/or computer readable media can adjust the identified steep changes in depth before determining one or more patient respiratory parameters.
