Abstract:
A method for blood pressure measurement, comprising applying a variable compressive acting pressure to a measuring point at a compression point by a pressure generator, and at the same time using a sensor to measure an arterial pressure pulse under the effect of the variable acting pressure on the artery at a second point, the second point being located farther away from the heart than the compression point to which the acting pressure is applied,characterized by providing a signal representing the measured value of the variable pressure acting on the measuring point at the compression point to an interpreting unit, sending a pressure pulse signal representing the measured arterial pressure pulse from the sensor to the interpreting unit, and determining diastolic pressure in the interpreting unit on the basis of the variable acting pressure when the interpreting unit detects a change in trend in a characteristic indicative of the magnitude of the pressure pulse in the pressure pulse signal from said sensor.
