Continuous Blood Pressure Measurements in Stress Situations

Cord Volker Bauch, Dieter Barschdorff

Abstract

When a person is exposed to physical and psychological challenge, the autonomic nervous system reacts in a way to cope the situation. Stress conditions are usually characterized by heart frequency or skin resistance changes. Though also the blood pressure is known to increase in stress situations, its measurement was not meaningful because of the insufficient time resolution of instruments using inflatable cuffs. We present the first model based continuous blood pressure determinations during stress tests. The measuring technique is based on the dependency of the systolic blood pressure on the pulse transit time and on individualized mathematical models. The Vienna Test System and car driving situations in the driving simulator "Nightdriver" are examined. With the new technique the blood pressure can be determined without interfering with the persons cognitive perceptions. It clearly correlates to different stress levels.
