A method and apparatus for measuring blood pressure by the oscillometric technique. The method incorporates variable PIP's (Parameter Identification Point). The method comprises the steps of obtaining a value for the peak amplitude Amax of an oscillometric envelope; determining a cuff pressure, CP , which corresponds in time with Amax, this pressure representing the MAP of t he subject; computing a variable value PIPSBP as a function of MAP (Mean Anteri al Blood Pressure); performing the calculation Asbp = Amax * PIPSBP to determin e a systolic amplitude value Asbp along the oscillometric envelope; and determining the cuff pressure C which corresponds in time to Asbp, this valu e representing the systolic blood pressure (SBP) of the subject. PIP can be calculated using a piece-wise linear, polynomial, exponential or other function.
