A blood pressure monitor for determining a patient's blood pressure comprises a processor attached to a first input device for receiving an initial input representing the patient's absolute blood pressure, and a noninvasive sensor attached to the patient for measuring at least one physiological function. The processor executes a procedure for evaluating the initial input and the sensed physiological function to determine the patient's blood pressure. A method for determining a patient's blood pressure comprises the steps of storing an initial input representing a patient's absolute blood pressure, noninvasively sensing at least one of the patient's physiological functions, and evaluating the initial input and the sensed input to determine the patient's blood pressure. The present invention can also be used to analyze and track other physiological variables such as vascular wall compliance, changes in the strength of ventricular contractions, changes in vascular resistance, changes in fluid volume, changes in cardiac output, myocardial contractility and other related factors.
