A system for monitoring blood pressure of a subject includes a primary system for determining a first blood pressure and a corrective system. The corrective system includes a cuff configured to be operated in an inflation phase and a deflation phase, a sensor array which produces inflation and deflation phase output signals, and a processor. The processor is configured to a) determine first and second output values from the inflation phase output signal and b) determine third and fourth output values from the deflation phase output signal. The processor is also configured to determine a correction applicable to the first blood pressure. The correction is a function of the first, second, third and fourth output values.
