Near-infrared spectroscopy for evaluation of global and skeletal muscle tissue oxygenation

Figure 1 Vascular occlusion test: An original thenar tissue oxygen saturation (StO₂) recording after arterial upper arm cuffing, and cuffing release (upper arm ischemia reperfusion test). During the upper arm ischemia reperfusion test, several StO₂ parameters can be studied: average StO₂ before arterial cuffing/occlusion; StO₂ downslope during cuffing-the deoxygenation rate (∆down StO₂)/s); StO₂ upslope (∆up StO₂)/s); hyperemia (overshoot of StO₂ above baseline).
