Abstract
A blood pressure measurement system comprises a determination means for determining whether a cuff pressure is increasing for preparation purposes or decreasing for measurement purposes. The determination means includes a comparator for comparing the current cuff pressure with the last cuff pressure, and detection means for detecting whether a difference between the current cuff pressure and the last cuff pressure is smaller than a predetermined value. Another determination means is provided for detecting whether the cuff pressure is first increased to a desired level higher than systolic pressure of a person to be measured. A reset means is provided for automatically resetting the system when the cuff pressure is decreased to a predetermined level after completion of measurement.
