BLOOD PRESSURE LEVEL CHANGE DETECTION APPARATUS, METHOD FOR DETECTING CHANGE IN BLOOD PRESSURE LEVEL, AND PROGRAM

摘要

This invention provides a blood pressure level change detection device which is capable of detecting a blood pressure level change in blood pressure time-series data, for example. A blood pressure level change detection device (300) is provided with a change point detection unit (352) and a level change/reversion determination unit (354). The change point detection unit (352) detects a first change point (CP1) as a change point in blood pressure time-series data (BTD1). The level change/reversion determination unit (354) acquires a first average blood pressure level (ABL1) and a second average blood pressure level (ABL2) for the blood pressure time-series data (BTD1). The level change/reversion determination unit (354) determines that a blood pressure level change has occurred at the first change point (CP1) when the difference between the first average blood pressure level (ABL1) and the second average blood pressure level (ABL2) is equal to or greater than a predetermined level threshold value (ABLth).
