Title: METHOD AND ARRANGEMENT FOR BLOOD PRESSURE MEASUREMENT
Abstract:
The invention relates to a method and 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 (3) or the like, at a compression point (A) by a pressure generator (1), and at the same time the effect of the variable pressure on the artery is measured at a second point (B), the 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 pressure is applied, and in the method diastolic pressure (PDIAS) and/or systolic pressure (PSYS) is determined to determine the measurement result of an actual measurement. In addition to the actual blood pressure measurement, the method comprises an estimation cycle for the actual measurement, during which the magnitude of the pressure pulse is measured by a sensor (7) measuring a pressure pulse signal, and in the estimation one or more statistical parameters are calculated from the pressure pulse measurement data to represent the magnitude of pressure pulse variation for forecasting and/or depicting the quality of the actual blood pressure measurement.
