Abstract: A system for monitoring autoregulation includes an oxygen saturation sensor configured to obtain an oxygen saturation signal indicative of an oxygen saturation of a patient. The system also includes a controller having a processor configured to receive a blood pressure signal indicative of a blood pressure of the patient and the oxygen saturation signal, determine a change in the oxygen saturation signal and a change in the blood pressure signal over a period of time, and provide an indication that the patient's autoregulation is intact if the oxygen saturation changes by more than an oxygen saturation threshold and if the blood pressure changes by less than a blood pressure threshold during the period of time.

Abstract: In some examples, a system is configured to determine, using a neural network algorithm of a cerebral autoregulation model, a cerebral autoregulation status of the patient based at least in part on a blood pressure of the patient over a period of time and regional cerebral oxygen saturation of the patient over the period of time.

Abstract: In some examples, a patient monitoring system includes processing circuitry configured to detect an occurrence of a nociception event of a patient during a medical procedure. The processing circuitry may, for example, determine, based at least in part on a nociception parameter of the patient in an interrogation window, a nociception parameter level, determine, based at least in part on the nociception parameter of the patient in a baseline window that corresponds to the interrogation window, a baseline nociception parameter level, determine a difference in nociception parameter levels between the baseline nociception parameter level and the nociception parameter level, detect, based at least in part on the difference in nociception parameter levels, an occurrence of a nociception event, and in response to detecting the occurrence of the nociception event, provide an indication to adjust an amount of analgesic administered to the patient.

Abstract: A patient monitoring system may include processing circuitry configured to receive an indication of a medical event, determine a set of nociception parameters of a patient that corresponds to the medical event, determine a nociception threshold based at least in part on the set of nociception parameters of the patient, compare a nociception parameter of the patient to the nociception threshold to detect a nociception event, and in response to detecting the nociception event, providing an indication to adjust an amount of analgesic administered to the patient.

Abstract: The present technology relates to patient monitoring systems and methods using plural PPG sensors in contact with a patient at different locations, wherein a comparison of the PPG data is performed to calculate a differential pulse transit time (DPTT) between the first and second locations, followed by a determination of continuous non-invasive blood pressure (CNIBP) using the PPG data from the plural and the calculated DPTT.

Abstract: The present invention relates to the field of medical monitoring, and in particular non-contact, video-based monitoring of pulse rate, respiration rate, motion, and oxygen saturation. Systems and methods are described for capturing images of a patient, producing intensity signals from the images, filtering those signals to focus on a physiologic component, and measuring a vital sign from the filtered signals.

Abstract: According to an aspect, a method and system for displaying heart rate variability on a display device includes obtaining patient heart rate variability from heart rate information. At least one indicator corresponding to the heart rate variability is superimposed over the heart rate variability on the display device and used to determine a patient status. The patient status is identified as it corresponds to the at least one indicator, such as a color, and communicated to a clinician. The device therefore provides a visual indication of patient status based on the graphic display of the heart rate variability. A minimum threshold value for the heart rate variability is indicated on the display device. An alarm is activated when the minimum threshold value of the heart rate variability is reached and deactivated when the heart rate variability exceeds the minimum threshold value.
