1. A method of monitoring blood pressure in a patient, the method comprising the steps of:

  • providing a continuous, non-invasive blood pressure (CNIBP) monitor operable to continuously estimate the blood pressure of the patient and generate a continuous blood pressure estimate;

    calculating a target inflation pressure based upon the continuous blood pressure estimate from the CNIBP monitor;

    positioning a blood pressure cuff on the patient;

    inflating the blood pressure cuff to the target inflation pressure;

    continuously decreasing the pressure in the blood pressure cuff while monitoring for oscillometric pulses in the blood pressure cuff; and

    calculating the systolic pressure, mean arterial pressure and diastolic pressure based upon the oscillometric pulses detected during deflation of the blood pressure cuff.
