Blood pressure level change detector, blood pressure level change detection method, and program

摘要

PROBLEM TO BE SOLVED: To provide a blood pressure level change detecting device capable of detecting a blood pressure level change in a time series data of blood pressure, for example. A blood pressure level change detection device 300 includes a change point detection unit 352 and a level change / return determination unit 354. The change point detection unit 352 detects the first change point CP1 as the change point in the blood pressure time series data BTD1. The level change / return determination unit 354 acquires the first average blood pressure level ABL1 and the second average blood pressure level ABL2 for the blood pressure time series data BTD1. The level change / return determination unit 354 determines the blood pressure 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 higher than the predetermined level threshold ABLth. Judge that a level change has occurred. [Selection diagram] Fig. 5
