Abstract: The present invention relates to a device, system and method for calibrating a blood pressure, BP, surrogate for use in monitoring a subject's blood pressure. The device comprises a BP input (51), a sensor input (52) and a processing unit (53) that is configured to compute a control signal for controlling the pressure-delivery system (10) to repeatedly inflate its cuff in directly consecutive partial inflations up to a cuff pressure equal to or below the subject's mean BP, compute pulse-related values from the first and second time-dependent sensor signals, measured during the repeated directly consecutive partial inflations of the cuff, using a first feature in the first time-dependent sensor signal and a second feature in the second time-dependent sensor signal, the pulse-related values being pulse arrival time, PAT, values or pulse transit time, PTT, values, and compute a calibration parameter for a BP surrogate from the BP measurement value and pairs of the pulse-related values and corresponding cuff pressure values, computed from the first and second time -dependent sensor signals measured during the repeated directly consecutive partial inflations of the cuff, a pair comprising a pulse-related value and a corresponding, temporally related cuff pressure value.

Abstract: The invention provides a control unit (12) and method for deriving a measure of arterial compliance based on an acquired arterial volume variation signal and an acquired pulse arrival time signal. An oscillometric blood pressure measurement device is used to acquire the arterial volume variation signal. Arterial volume and variation in pulse arrival time are both measured as an applied pressure to an artery are varied by the oscillometric blood pressure measurement device. The arterial volume signal is transformed into a corresponding signal representative of variation in peak-to-peak amplitude of the arterial volume. A first model fitting procedure is used to transform this peak-to-peak amplitude signal into a signal indicative of arterial volume as a function of transmural pressure. A second model fitting procedure is used to generate from the derived arterial volume vs. transmural pressure signal, and the derived pulse arrival time variation signal a final output measure of arterial compliance.
