Paper Abstract

Medical shock is still a common cause for the unacceptably high mortality rate in trauma patient in Intensive Care Units (ICU), because limitations of the monitoring/ diagnostic techniques and short time span of shock development. In this paper we introduce a method for monitoring of the vessel density spatial pattern, using spatially resolved diffuse reflectance measurement. The setup contains a spatially resolved optical fiber probe coupled to supersensitive spectrometer and high power light source. The experiment was done on skin tissue phantom model containing grid pattern which mimicks optical properties of the skin and capillary network. The spatially resolved diffuse reflectance spectra are collected over the phantom with various detector to source distance. The measured spatially resolved diffuse reflectance spectra were analyzed yielding grid spatial pattern. This novel technique of the vessel density spatial pattern monitoring will help to detect the early signs of shock development in intensive care units.
