1. A method for estimating systolic blood pressure and diastolic blood pressure comprising:

  • obtaining a predetermined type of blood pressure data from a patient;

    providing previously acquired blood pressure data obtained from a plurality of different subjects, said previously acquired blood pressure data adapted to convey the manner in which a systolic amplitude ratio and a diastolic amplitude ratio vary with respect to the predetermined type of blood pressure data obtained from the patient;

    implementing the previously acquired blood pressure data to select a systolic amplitude ratio and a diastolic amplitude ratio that most closely correlate with the predetermined type of blood pressure data obtained from the patient, wherein the selected systolic amplitude ratio and diastolic amplitude ratio are adapted to compensate for the effects of arterial compliance;

    implementing the selected systolic amplitude ratio to estimate a systolic blood pressure level; and

    implementing the selected diastolic amplitude ratio to estimate a diastolic blood pressure level.
