A method and arrangement for blood pressure measurement are disclosed. In the method, a variable, compressive, acting pressure is applied to a compression, such as a person's extremity, by a pressure generator, and simultaneously, the effect of the variable acting pressure on the extremity is measured at a second point, the second point being farther from the heart than the compression point. The method determines diastolic and systolic pressure. The measured value of the variable acting pressure acting on the compression point is transferred to an interpreting unit, which also receives a pressure pulse generated by the heart. The pressure pulse is measured by a sensor at the second point for determining the effect of the variable acting pressure on the extremity. Further, diastolic pressure is determined int he interpreting unit based on the variable acting pressure, as the pressure when the interpreting unit detects a change in a trend of a characteristic of the pressure pulse indicative of magnitude.
