  1. DeO2ratio quotient between StO2-deoxygenation rate at the end of SBT and at baseline, nirVO2ratio quotient between NIRS-derived local oxygen consumption at the end of SBT and at baseline, HAUC area under the curve of the hyperemic response, StO2 tissue oxygen saturation, ScvO2 central venous oxygen saturation, % change in ScvO2 refers to the % change in ScvO2 at min 30 of the SBT as compared to baseline ScvO2
