An apparatus for estimating a core body temperature of an object is provided. According to one embodiment, the apparatus includes a plurality of sensors configured to obtain data from an object and a processor configured to obtain a surface temperature, a heat flux, a skin blood flow rate, and a blood flow velocity by using the data obtained from the plurality of sensors, obtain a skin thermal conductivity based on the skin blood flow rate, and estimate a core body temperature of the object based on the surface temperature, the heat flux, the skin thermal conductivity, and the blood flow velocity of the object.

An arousal state estimation apparatus includes: a feature value acquisition unit acquiring a plurality of types of feature values regarding an arousal state of a human body from physiological data obtained by measuring the human body; and an estimation unit estimating the arousal state of the human body by using a principal feature value that is some type among the plurality of types of feature values. In a case where the principal feature value is unacquirable due to a defect of the physiological data, the estimation unit estimates the arousal state of the human body by using a different type of feature value than the principal feature value among the plurality of types of feature values acquired by the feature value acquisition unit instead of the unacquirable principal feature value.

A method of monitoring cardiac dysfunction, such as pericardial effusion, is disclosed. The method uses an indwelling probe inserted within a coronary sinus or a chamber or vessel of the heart, the probe having motion sensing means configured to sense motion of the probe based on movement of the wall of the coronary sinus or other chamber or vessel. Data is obtained from the motion sensing means and processed to monitor for cardiac dysfunction. The monitoring can be in real-time and can utilise one or more three-axis accelerometers. In some embodiments, two or more three-axis accelerometers are spaced longitudinally along an elongate body of the probe, which can increase accuracy and reliability of monitoring.
