DIAGNOSTICS OF THE HUMAN CIRCULATORY SYSTEM: HIGH RESOLUTION BEAT-TO-BEAT MEASUREMENT OF SYSTOLIC BLOOD PRESSURE USING PERSONALIZED MODELS

Dieter Barschdorff, Cord Bauch

Abstract

Blood pressure and heart rate monitoring allow evaluating the cardiovascular efficiency and point out how the circulatory system responds to stress and exercise. Especially the blood pressure indicates the ability of a person to withstand emotional and physical stress. For blood pressure measurement oscillometric or Riva-Rocci/Korotkow based instruments are used as standard devices. Their severe drawback is the low time resolution preventing the registration of dynamic cardiovascular changes. We present a new high resolution continuous blood pressure measure technique based on individualized mathematical models. The method can be applied without interfering with the subjects cognitive perceptions. Beside calibration tests we present the first continuous measurements during stress and traffic situations. Characteristic pros and cons of the new method, the accuracy and new diagnostic possibilities are discussed.
