  Purpose

The Diffuse Optical Spectroscopy (DOS) measure the absolute concentrations of reduced and oxygenated hemoglobins ([Hb-R] and [HbO2], respectively) as well as the water and lipid concentrations of the tissue.

Detailed Description:

DOS have been shown to correlate with invasive measures of cardiac output, mean arterial pressure, blood loss, and blood hemoglobin concentration.

The researchers want to use DOS as a means to monitor volume changes during the hemodialysis treatment and to correlate the changes in volume and blood pressure with the measures of oxidative stress and inflammation used in this study.

The researchers want compared to a variety of laboratory parameters routinely measured in CKD subjects (GFR, proteinuria, Hg, serum albumin, bicarbonate, calcium, phosphorous, iron saturation, ferritin, lipid profiles, PTH) and to clinical parameters such as cause of CKD, blood pressure and dialysis-related parameters.
