ABSTRACT:
A method for determining blood pressure of an artery includes the steps of applying a pressure to the artery, sensing pressure data produced by the artery and deriving parameters for the sensed pressure data. The parameters are utilized for generating a first blood pressure value estimate using a first function of the parameters based upon a first range of pressure values and by generating at least one second blood pressure estimate using at least one second parameter function based upon a second blood pressure estimate using at least one second parameter function based upon a second pressure range different from the first pressure range. A blood pressure value is determined based upon the first blood pressure estimate and said at least one second blood pressure estimate.
