Abstract
An apparatus for automatically measuring blood pressure of a subject based on heartbeat-synchronous pulses, the apparatus having a device including a cuff and detecting a magnitude of each of the pulses produced from the subject as pressure in the cuff is varied, a device for collecting not less than a first number of the detected pulses, and plotting a corresponding number of points in a table defined by a first axis indicative of the cuff pressure and a second axis indicative of the pulse magnitude, such that each of the plotted points represents a cuff pressure at a time of detection of a corresponding one of the collected pulses and a pulse magnitude of the corresponding one pulse, a device for selecting a second number of consecutive points from the plotted points and determining a regression line of the selected points, a device for determining, based on the regression line, at least one expected pulse magnitude regarding at least one point adjacent to the selected points, a device for determining a temporary maximum blood pressure based on the at least one point if a pulse magnitude represented by each of the at least one point is higher than a corresponding one of the at least one expected pulse magnitude, a device for determining a proper maximum blood pressure, and a device for displaying the temporary maximum blood pressure prior to the proper maximum blood pressure.
