Abstract
The oxygenation state of the blood is a key determinate of physiological state of patient. Several techniques are available for determining the average oxygenation state of the blood in a tissue. However, these techniques cannot resolve relative local volume fractions of reduced/- oxyhemoglobin concentration within the bulk of a highly scattering tissue. Prompt detection of these parameters are important for the clinical diagnosis and effective treatment planning in ICU patients. Therefore, aim of this study is to detect local volume fractions of reduced/- oxyhemoglobin concentrations. The diffuse reflectance spectroscopy can non-invasively measure the various pathophysiological functions by measuring the absorption from blood. Thus, in this study relative local volume fractions of reduced hemoglobin and oxyhemoglobin concentration are measured from the capillary beds close to the upper layer of the lips through the diffuse reflectance spectra.
