1. A system for monitoring blood pressure of a subject comprising:

  • a primary system for determining a first blood pressure; and

    a corrective system comprising;

    a cuff configured to be operated in

         1) an inflation phase to at least partially occlude an artery of the subject and

         2) a deflation phase;

    a sensor array configured to A) receive an inflation phase input signal associated with the at least partially occluded artery, B) generate an inflation phase output signal based on the received inflation phase signal, C) receive a deflation phase input signal associated with the artery, and D) generate a deflation phase output signal based on the received deflation phase signal; and

    a processor configured to a) receive the inflation phase output signal and determine therefrom first and second output values, b) receive the deflation phase output signal and determine therefrom third and fourth output values, and c) determine a correction applicable to the first blood pressure, the correction being a function of the first, second, third and fourth output values.
