Abstract: There is provided a method of providing information about prognosis after cardiac arrest. The method includes the steps of: calculating biological information based on a signal relating to a hemoglobin concentration measured from a cerebral region of a subject to be measured; and providing the information about the prognosis after cardiac arrest of the subject with reference to the calculated biological information and a biomarker relating to the prognosis after cardiac arrest measured from a blood of the subject.

Abstract: A method of monitoring a body tissue includes determining, with reference to a position of an m-th light emitting unit, a position of an n-th light reception unit, and a distance between the m-th light emitting unit and the n-th light reception unit, an area and a depth of the body tissue which corresponds to the m-th light emitting unit and the n-th light reception unit; measuring hemodynamics of the body tissue at the area and the depth corresponding to the m-th light emitting unit and the n-th light reception unit based on the optical signal generated from the m-th light emitting unit and detected by the n-th light reception unit; and estimating an activity of the body tissue on an area basis and a depth basis based on the hemodynamics at at least one of the area and the depth of the body tissue.

Abstract: According to one aspect of the invention, there is provided a method for controlling a monitoring device including a plurality of light emission units (or sources) and a plurality of light reception units (or detectors), comprising the steps of: causing the plurality of light emission units to sequentially generate optical signals in a mutually exclusive manner according to a time division scheme; and with reference to a distance between an m-th light emission unit of the plurality of light emission units that generates an optical signal to be measured and an n-th light reception unit of the plurality of light reception units that detects the optical signal to be measured, dynamically controlling a measurement circuit gain that the n-th light reception unit uses to detect the optical signal generated by the m-th light emission unit.
