Best dynamic wavelength range for shock detection via blood vessel density pattern

Diffuse reflectance spectroscopy is a non-invasive or minimally invasive medical diagnostic modality. Still challenges in noninvasive tools for early shock detection are unresolved especially in spatial resolution and broad range of sampling wavelength for reduced-/ oxy-hemoglobin concentrations detection from tissue sample. To minimize these limitations, we have developed a novel method based on spatially and spectrally resolved diffuse reflectance for shock detection. This study was performed to pick up best dynamic wavelength range sets to detect fine vessel density pattern modulation for shock detection.
