Abstract
Indirect blood pressure measurement for a systolic or diastolic blood pressure is accomplished by making use of a true Korotkov sound determination. When three or four Korotkov sound signals are found in four successive heart pulses of a body, each of the three or four Korotkov sound signals is determined as a true Korotkov sound signal. A cuff pressure existing when the first true Korotkov sound appears is determined as a systolic blood pressure. Another cuff pressure existing when the last true Korotkov sound signal appears is determined as a diastolic blood pressure. The last true Korotkov sound signal is determined by counting three heart pulses unaccompanied by no Korotkov sound signals following the detection of the last true Korotkov sound appearance.
