HYPOTENSION-PREDICTING DEVICE

摘要

A blood pressure decrease prediction apparatus (100) predicts a decrease in blood pressure of a living body (900) who is, for example, a patient receiving artificial dialysis. The blood pressure decrease prediction apparatus is provided with: a pulse rate calculating device (110) which is configured to calculate a pulse rate of the living body; a blood flow volume calculating device (120) which is configured to calculate a blood flow volume of the living body; a risk level determining device (150) which is configured to determine a risk level which indicates a risk of occurrence of the decrease in blood pressure, on the basis of a variation in at least one of the calculated pulse rate and the calculated blood flow volume; and a high risk level judging device (160) which is configured to judge that it is in a high risk level state in which the risk of occurrence of the decrease in blood pressure is higher than the determined risk level, if a variation range of at least one of the calculated pulse rate and the calculated blood flow volume during a predetermined period exceeds a threshold value which is determined in accordance with the determined risk level. This makes it possible to predict the decrease in blood pressure of the living body at an early stage and with high accuracy.
