Method and arrangement for blood pressure measurement

An arrangement for blood pressure measurement, comprising:

• a pressure generator for applying an acting pressure to a measuring point, such as a person's extremity or the like,
• a measuring element for measuring the acting pressure,
• an interpreting unit for determining systolic pressure (PSYS) and/or diastolic pressure (PDIAS),
• a sensor for simultaneous measurement of the effect of the variable pressure on an artery at a second point, said second point being farther away from the heart, i.e. closer to the end point of peripheral circulation, than the compression point to which the acting pressure is applied, and
• estimation means for estimating the quality of an actual blood pressure measurement, and that the estimation means is in connection with the sensor measuring the pressure pulse at the measuring point and feeding the measurement data to the estimation means, the sensor being either the same sensor that is used in the actual blood pressure measurement for measuring the effect of the acting pressure, or a second, different sensor, and that the estimation means further includes a calculation means, adapted to calculate from the measurement data measured by the pressure pulse sensor one or more statistical parameters representing the magnitude of pressure pulse variation for forecasting and/or depicting the quality of the actual blood pressure measurement.

An arrangement for blood pressure measurement, comprising:

• a pressure generator for applying an acting pressure to a measuring point, such as a person's extremity or the like,
• a measuring element for measuring the acting pressure and its effect by measuring a pressure oscillation signal of the pressure generator,
• an interpreting unit for determining systolic pressure (PSYS) and/or diastolic pressure (PDIAS) oscillometrically from the pressure oscillation signal, and
• estimation means for estimating the quality of an actual blood pressure measurement, and that the estimation means is in connection with the measuring element or with a sensor measuring the pressure oscillation signal and feeding the measurement data to the estimation means, and that the estimation means further includes a calculation means, adapted to calculate from the measurement data of the measured pressure oscillation signal one or more statistical parameters representing the magnitude of pressure oscillation signal variation for forecasting and/or depicting the quality of the actual blood pressure measurement.
