ABSTRACT:
A method and apparatus are disclosed for tracking instantaneous changes in blood pressure. The invention is utilized in an oscillometric blood pressure measuring apparatus of the type measuring pulsatile perturbations in a patient's blood pressure at a plurality of different measurement pressures of a sphygmomanometer cuff, to derive a blood pressure model for the patient, the model being stored in the apparatus as a series of pulsatile perturbations and the associated cuff pressures. A characteristic curve is generated so as to approximate the stored model in the vicinity of a predefined index value of cuff pressure. The pressure of the cuff is maintained within a predetermined range, r, of the index value, while changes in the index value are tracked by sensing a pulsatile perturbation in the cuff pressure, deriving the corresponding value for cuff pressure from the characteristic curve, and utilizing the derived pressure as a new estimate for the index value. In a preferred embodiment, the characteristic curve is realized as an equation defining a straight line.
