  • Publication number: 20210361178
    Abstract: A blood pressure level change detection apparatus includes a change point detection unit and a level change/return determination unit. The change point detection unit detects a first change point as a change point in time-series data of blood pressure. A level change/return determination unit acquires a first average blood pressure level and a second average blood pressure level for time-series data of blood pressure. When a difference between the first average blood pressure level and the second average blood pressure level is greater than or equal to a predetermined level threshold value, the level change/return determination unit determines that a blood pressure level change has occurred at the first change point.
