Reproduction of central-brachial-radial arterial blood pressure wave propagation using a cardiovascular hardware simulator.

Abstract

This study reproduced changes according to the central-brachial-radial blood pressure wave propagation using a cardiovascular hardware simulator. Blood pressure is a key indicator of cardiovascular health, and its importance has recently emerged, and research into the correlation between the two is in progress. This requires a large amount of clinical data, but the amount and distribution are limited. The hardware simulator in this study mimics the structure and properties of the human cardiovascular system. This reproduces the pulse wave velocity and the generation of a blood pressure wave. The reproduced central-brachial-radial blood pressure waves are similar to those of humans in magnitude, waveform, and changes due to propagation. Blood pressure waves propagate from the central aorta to the radial artery, showing waveform changes due to systolic amplification and reduced overlap area. Reproducing these blood pressure waveforms can compensate for the lack of quantity and quality in clinical data. In the future, it can be expanded to a testbed for health sensors and research on the origin of bio-signals through the addition of upper arm and wrist phantoms.
