Correlations among Tissue oxygenation variables and Microcirculation variables. A Tissue oxygen consumption (NIRVO2) significantly correlates positively with microvascular reactivity (recovery - upslope) in both the full sample (r = 0.442, p = 0.045) and in the subgroup sample (r = 0.775, p = 0.005). B Small vessel Microvascular Flow Index (MFIsmall--marker of flow) correlates positively with proportion of perfused small vessels (PPVsmall--marker of perfusion) in the subgroup sample (not statistically significant; r = 0.435, p = 0.182).
