A blood pressure value analysis support apparatus includes a one-beat reliability determination unit and section setting unit. The determination unit determines reliability of a blood pressure value for each beat including a first reliability and second reliability lower in reliability than the first based on information indicating disturbance. The section setting unit sets valid and invalid sections for the time-series data of blood pressure based on a reliability determination result. The section setting unit includes a section wherein the blood pressure value reliability for each beat is the first reliability in the valid section and includes a section wherein the blood pressure value reliability for each beat is the second reliability in the invalid section, for the time-series data of blood pressure. The section setting unit changes the invalid section when a length of a continuous period is less than a preset first threshold value to the valid section.

The present invention has a normal blood pressure measurement mode in which a blood pressure measurement is performed according to a blood pressure measurement instruction, and a nighttime blood pressure measurement mode in which a blood pressure measurement is automatically started according to a predetermined schedule. When being switched by an mode operation unit from the normal blood pressure measurement mode to the nighttime blood pressure measurement mode, an algorithm for blood pressure calculation by an oscillometric method is switched and set from an algorithm for a sitting position to an algorithm for a supine position. A blood pressure value is calculated using an algorithm currently set for the blood pressure calculation by the oscillometric method.

In the present invention, date and time are set in a horizontal direction and blood pressure is set in a vertical direction on a display screen, and a change in a blood pressure value over a display target period is displayed as a bar graph with vertical bars each formed by connecting SBP and DBP for each time and arranged in the horizontal direction. When a position corresponding to a vertical bar at a specific time on the display screen is designated with a pointing device, blood pressure value data measured for each day at the specific time are averaged over the display target period to obtain a systolic blood pressure average value and/or a diastolic blood pressure average value, according to the position designated. The obtained systolic blood pressure average value and/or diastolic blood pressure average value is displayed together with the bar graph on the display screen.

According to the present invention, blood pressure surges is detected from time-series data on blood pressure of a subject that varies with pulsation based on predetermined determination criteria. A feature amount indicating a characteristic of each blood pressure surge thus detected is obtained. Statistical processing is performed on an occurrence number of the blood pressure surges thus detected and/or the feature amount to obtain a statistical amount for each of time slots. A required attention degree indicating a level of attention being required to the blood pressure surge is obtained for each of the time slots based on the statistical amount of the occurrence number of the blood pressure surges and/or the feature amount. The required attention degree thus obtained and/or the statistical amount are displayed side by side for each of the time slots on a display screen.

According to the present invention, blood pressure surges are detected from time-series data on blood pressure of a subject that varies with pulsation based on predetermined determination criteria. For each blood pressure surge thus detected, an envelope connecting a plurality of pulse-corresponding peaks forming the blood pressure surge is acquired as an individual waveform. Statistical processing is performed on a plurality of individual waveforms to obtain a representative waveform and waveform variation among the blood pressure surges in the time-series data. On a display screen, a curve indicating the representative waveform is displayed with the curve superimposed on a region indicating the waveform variation among the blood pressure surges.
