DIAGNOSTICS OF THE HUMAN CIRCULATORY SYSTEM: APPLICATION OF HIGH RESOLUTION BEAT-TO-BEAT BLOOD PRESSURE MEASUREMENT TO STRESS AND TRAFFIC SITUATIONS |

- Abstract:
- When a person is exposed to physical and psychological challenge, the heart beat is increased, blood vessels are dilated, the blood pressure increases and the skin resistance decreases. While heart rate and skin resistance can easily be measured, continuous blood pressure measurement was not possible in stress situations because of the poor time resolution of oscillometric or Riva-Rocci/Korotkow based instruments. We apply a novel high resolution blood pressure measurement technique based upon the pulse transit time dependency on the systolic pressure and making use of individualized mathematical models. The method can be used without interfering with the persons cognitive perceptions. Thus we can present the first continuous blood pressure measurements during stress tests utilizing the Vienna Test System and the driving simulator "Nightdriver".
