Abstract

Development of a noninvasive flow measurement for the blood glucose level was performed by extracting frequency components from the blood flow velocity waveform during an OGTT (Oral Glucose Tolerance Test). The index, P_G, was obtained by calculating the ratio of changes in the power spectrum of the waveform to the changes in the level of blood glucose. They were classified into three groups, normal, diabetics with and without showing neuropathic subjective symptoms. The resulting indices calculated were P_G(N)=1.0±0.2, P_G(DN+)=0.1±0.08, and P_G(DN-)=0.3±0.1. The conclusions drawn from the experiment indicated that the spectral analyses of the blood flow waveform could be used as a significant indicator for the blood glucose level
