Abstract:
A method for blood pressure measurement, the method comprising applying a variable compressive acting pressure to a measuring point, such as a person's extremity or the like, at a compression point by a pressure generator, and at the same time measuring the effect of the variable pressure on the artery at a second point located farther away from the heart, i.e. closer to the end point of peripheral circulation than the compression point to which the pressure is applied, wherein diastolic pressure (PDIAS) and/or systolic pressure (PSYS) is determined as a result of an actual blood pressure measurement,characterized in that in addition to the actual blood pressure measurement, the method comprises using an estimation cycle for the actual measurement, during which the magnitude of a pressure pulse is measured by a sensor measuring a pressure pulse signal, and that 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.
