1. A blood pressure monitoring apparatus for repetitively measuring blood pressure of a subject, comprising:
- measuring means for measuring at least one of a maximum, a minimum and an average blood pressure of a subject at each of repetitive measuring cycles; and
display means for displaying a time-wise varying trend of said at least one of maximum, minimum and average blood pressure, by indicating a graph representing the repetitively measured values of said at least one blood pressure in a two-dimensional table defined by a first axis indicative of time and a second axis indicative of blood pressure.

Abstract
A blood pressure monitoring apparatus for repetitively measuring blood pressure of a subject, including a measuring device for measuring a blood pressure of the subject at each of repetitive measuring cycles, and a display device for displaying a time-wise varying trend of the repetitively measured blood pressures in a two-dimensional table defined by a first axis indicative of time and a second axis indicative of blood pressure.

13. A blood pressure monitoring apparatus, comprising:
-
measuring means for measuring at least one of a maximum, a minimum and an average blood pressure of a subject at each of repetitive measuring cycles; display means for displaying a time-wave varying trend of said at least one of maximum, minimum and average blood pressures, by indicating a graph representing the repetitively measured values of said at least one blood pressure in a two-dimensional table defined by a first axis indicative of time and a second axis indicative of blood pressure; calibrating means for calibrating said second axis of said two-dimensional table by adjusting an upper and a lower limit of said second axis, said calibrating means determining, if a value of said at least one blood pressure measured at each measuring cycle does not fall in a range defined between a preceding pair of upper and lower limits of said second axis which have been used at at least a measuring cycle preceding said each measuring cycle, another pair of upper and lower limits according to a first predetermined relationship between blood pressure and second-axis upper limit and a second predetermined relationship between blood pressure and second-axis lower limit, respectively, based on the value of said at least one blood pressure measured at said each measuring cycle, such that all the values of said at least one blood pressure that have been measured before, and at, said each measuring cycle fall in a range defined between said another pair of upper and lower limits; and said display means displaying, in place of said preceding pairs of upper and lower limits, said another pair of upper and lower limits in the vicinity of corresponding ends of said second axis, and displaying said time-wise varying trend in the two-dimensional table having the second axis calibrated with said another pair of upper and lower limits. - View Dependent Claims (14, 15, 16, 17, 18)
