Abstract:
1. A blood pressure measurement apparatus for measuring blood pressure in a predetermined period, comprising: a blood pressure measuring unit that measures the blood pressure of a subject; an information acquiring unit that acquires information that is related to variation in blood pressure and changes in a time-series in the predetermined period; a determining unit that determines whether or not the information acquired by the information acquiring unit satisfies a predetermined condition; and a trigger output unit that, in a case where the determining unit determines that the predetermined condition is satisfied, causes the blood pressure measuring unit to start and execute blood pressure measurement, wherein the predetermined condition is expressed as a function of time that varies and is measured in the predetermined period, wherein the predetermined condition includes a threshold value, wherein the function is a function that changes the threshold value in accordance with the length of elapsed time from when the blood pressure measuring unit was most recently started, and wherein the determining unit acquires a feature value based on a value indicated by the information in a process of change in the time-series, and calculates the threshold value using the feature value.
