Derivation of an RBC velocity-adjusted perfused boundary region. a Box plots showing PBRstatic (D 4 to 25 µm) in healthy controls (green) and sepsis patients (red). b Scatter dot plots and simple linear regression (slope) with 95% confidence intervals of PBRstatic (D 4 to 25 µm) plotted against VRBC in feed vessels (D ≥ 10 µm). Different states at the ends of the slope lines (indicated by green/red bold letters A-D) are further explained in Fig. 6. c Box plots of PBRdynamic, a velocity-adjusted estimate of the PBR where the VRBC (D ≥ 10 µm) was set to 0 µm/s.
