Wavelet-Based Fluctuation Analysis of Laser Doppler Blood Flux on Renal Cortex in Rats.

摘要

Fluctuations of peripheral blood flux are related to its physiological or pathological condition. The oscillations of skin and muscle are well studied. Due to hard to install the probe, fewer studies about the oscillation of fluctuations of peripheral blood flux on internal organ are investigated. In this study, using a fast Laser-Doppler flowmetry (LDF) with a signal fiber probe, we measured the renal cortical flux (RCF) and abdominal aortic blood pressure (AABP) simultaneously in rats. With a continuous wavelet transform, we analyzed the fluctuations of RCF and estimate their weights on RCF.
