<p>The invention relates to a method and an arrangement for blood pressure measurement. In the method a variable compressive acting pressure is applied to a measuring point, such as a person's extremity or the like, at a compression point (A) by a pressure generator (1), and at the same time the effect of the variable acting pressure on the artery is measured at a second point (B), said second point (B) being located farther away from the heart, i.e. closer to the end point of peripheral circulation, than the compression point (A) to which the acting pressure is applied, and in which method diastolic and/or systolic pressure is determined. It is essential that the measured value of the variable pressure acting on the measuring point at the compression point (A) is tranferred to an interpreting unit (9) to which is also applied the pressure pulse generated by the heart and measured by a sensor (7) at said second point (B) for determining the effect of the variable acting pressure, and that the diastolic pressure (PDIAS) of the blood pressure measurement is determined in the interpreting unit (9) on the basis of an acting pressure which is measured by a measuring element (5) and is the acting pressure when the interpreting unit (9) detects a sufficiently long-standing change characteristic of systolic and/or diastolic pressure in a pressure pulse signal measured by said sensor (7).</p> |
