1. A method for determining blood pressure of an artery, the method comprising:

  • applying pressure to the artery;

    sensing pressure data produced by the artery;

    deriving parameters from the sensed pressure data;

    generating a first blood pressure estimate from the derived parameters using a first parameter function based upon a first pressure range of possible blood pressure values;

    generating at least one second blood pressure estimate from the derived parameters using at least one second parameter function based upon a second pressure range of possible blood pressure values, in which the second pressure range is different from the first pressure range; and

    determining a blood pressure value based upon the first blood pressure estimate and said at least one second blood pressure estimate.
