<P>PROBLEM TO BE SOLVED: To easily detect an abnormal generation such as the cerebral anemia in the living body without needing the measurement of electrocardiographic data. <P>SOLUTION: A pulse measuring instrument 12 measures pulse rate based on a pulse signal from a pulse oximeter 8 attached to a finger-tip of the living body. A CVPR calculation unit 13 calculates the CVPR based on a pulse rate measured by the pulse measuring instrument 12. A control unit 18 displays a comfortable degree of the living body based on the CVPR (coefficient of variation of pulse rate) calculated by the CVPR calculation unit 13, and controls a display unit 22 to display the tension degree of the living body based on an increase or decrease in past eight beats of the pulse rate measured by the pulse measuring instrument 12. The control unit 18 informs that there is a possibility of abnormality such as the cerebral anemia to occur in the living body, when the pulse rate measured by the pulse measuring instrument 12 decreases more than eight beats in series, and the CVPR calculated by the CVPR calculation unit 13 exceeds a preset threshold, for example, ≥7%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
