    摘要: A system and method for monitoring a patient experiencing an administration of at least one anesthetic drug. In certain embodiments, the method includes arranging sensors configured to acquire physiological data from a patient and reviewing the physiological data from the sensors and an indication received from an input. The method also includes assembling the physiological data into sets of time-series data and determining, from the sets of time-series data, a first set of signals in a first frequency range and a second set of signals in a second frequency range, the first set of signals describing a transient oscillation signature and the second set of signals describing a target wave signature. The method further includes identifying, using the transient oscillation and target wave signatures, a degree of sedation consistent with the administration of the anesthetic drug, and generating a report indicative of the degree of sedation induced by the drug.

    摘要: Systems and methods are provided for monitoring a subject, and particularly, for inferring an underlying brain state present in absence of current conditions. In some aspects, a method for monitoring the subject is provided including steps of receiving physiological feedback from at least one sensor configured to acquire physiological information from locations associated with a subject's brain, assembling a set of time-series data using the received physiological feedback, and identifying portions of the set of time-series data that indicate a burst suppression state. The method also includes identifying a burst characteristic profile associated with a burst pattern determined from the identified portions, and comparing the burst characteristic against a reference set of burst profiles. The method further includes determining, based on the comparison, a likelihood of a brain state of the subject underlying the burst suppression state, and generating a report indicative of the likelihood of the determined brain state.
