Abstract

We present a new application of Broadband Frequency Domain Near Infrared Spectroscopy (NIRS): monitoring end stage kidney disease (ESKD) patients undergoing hemodialysis (HD). The custom NIRS system combines frequency domain (FD) and broadband continuous wave (CW) measurements. FD and CW measurements were integrated using model-based analysis to provide broadband absorption and reduced scattering changes. Across twenty-seven HD subjects a notable difference in the ratio of water to total water-lipid concentration between adverse and non-adverse event groups (p
