A portable diffuse correlation spectroscopy (DCS) flowmeter has been extended to measure both tissue blood flow and oxygenation (namely, DCS flow oximeter). For validation purposes, calf muscle blood oxygenation during cuff inflation and deflation was measured concurrently using the DCS flow oximeter and a commercial tissue oximeter. The oxygenation traces from the two measurements exhibited similar dynamic responses, and data were highly correlated (r(mean)>0.9, P<10(-5), n=10). The portable, inexpensive, and easy-to-use DCS flow oximeter holds promise for bedside monitoring of tissue blood flow and oxygenation in clinics.
一种便携式漫反射相关光谱（DCS）流量仪已被扩展，以同时测量组织血液流量和氧合（即 DCS 流量血氧计）。为了验证目的，使用 DCS 流量血氧计和商业组织血氧计同时测量充气和放气期间的小腿肌肉血氧饱和度。两种测量方法的氧合轨迹表现出相似的动态响应，并且数据高度相关（r（平均值）>0.9，P<10（-5），n=10）。这种便携式、价格低廉且易于使用的 DCS 流量血氧计有望在临床上用于床边监测组织血液流量和氧合。
