| Summary: | 碩士 === 國立交通大學 === 顯示科技研究所 === 99 === Microcirculation is the important mechanism to maintain the tissue metabolism. Therefore, the condition of microcirculation can provide useful physiological information.
Diffuse optical image system with continuous wave laser diode and photodiode on flexible black rubber was designed to evaluate the microcirculation condition by measuring the information of oxy-hemoglobin, deoxy-hemoglobin, total hemoglobin and tissue oxygen saturation.
In this thesis, the difference of venous occlusion hemodynamics are observed in vivo measurements form normal subjects, patients with heart failure and sepsis in intensive care unit. The correlation between artery occlusion test and far infrared illumination test in normal subjects are observed.
