EMPHO-Oxygradient I for Monitoring in Skin and Skeletal Muscle

摘要

This optical sensor system of high light sensitivity provides adequate prerequisites for tissue spectrometry in anesthesia and intensive care medicine. It can be applied for measurements of absolute hemoglobin concentration and oxygenation. In hemoglobin free perfused organs during transient hemoglobin free perfusion, monitoring of light scattering and oxygenation measurements of myoglobin and cytochromes are possible. Due to data base of spectra of organs high precision of optical parameters (μs and μa) can be attained. Calibration of light intensities of irradiated and backscattered light are performed by the computer system.
