Abstract

Blood flow and oxygen supply to skeletal muscle is a potentially important factor to maintain muscular oxygenation metabolism. In clinical usage, a well-functioned noninvasive system for measuring the muscular blood flow and metabolism is needed. Recently, near-infrared spectroscopy (NIRS) has been developed and become a useful technique for noninvasive monitoring of the regional oxygen supply. From this point of view, the authors proposed a new system to monitor and evaluate the regional oxygen saturation rSO2 and volume of hemoglobin using hemoglobin index (HbI) more simply and inexpensively for clinical application. The aim of this study is to estimate the oxygen metabolism in human muscles during physical exercise by using NIRS system and cycle ergometry.

近红外光谱法测量肌肉区域氧化代谢

骨骼肌的血流量和供氧是维持肌肉氧合代谢的潜在重要因素。在临床应用中，需要一个功能良好的无创系统来测量肌肉血流量和新陈代谢。近年来，近红外光谱(NIRS)已成为一种无创监测区域供氧的有效技术。基于此，作者提出了一种利用血红蛋白指数(HbI)监测和评价局部氧饱和度rSO2和血红蛋白体积的新系统，可用于临床应用。本研究的目的是利用近红外光谱(NIRS)系统和周期几何来估计运动过程中人体肌肉的氧代谢。
