Abstract

Simultaneous measurements of the low frequency fluctuations of arterial blood pressure, heart rate, tissue blood content and tissue blood volume pulse were performed on 20 healthy male subjects. Arterial blood pressure was measured on the index finger by Finapres, simultaneously with photoplethysmography (PPG), which was measured on the other index finger. The changes in the PPG amplitude (AM), baseline (BL), and BV (defined by BV equals Const. - BL), are related to the changes in the tissue blood volume pulse (for AM) and the total tissue blood volume, (for BL and BV). The low frequency fluctuations of BV and AM were directly correlated, those of AM preceding those of BV by 4 - 13 heart beats. The low frequency fluctuations of SBP and DBP were inversely correlated to those of AM and BV. For most of the subjects P, which is the cardiac cycle period, was directly correlated with AM and BV. The interrelationship between the low frequency fluctuations in tissue blood volume, arterial blood pressure and heart period, provide us with a better understanding of the autonomic nervous control of the peripheral circulation.
