A time-scaled overview of the total experiment. The experiment was 4 h in total and can globally be split up into four different experiments; the reperfusion of the kidney, a stepwise modulation of arterial renal flow, the induction of a local ischemic area, and the gas bubble infusion of ${\mathrm{O}}_2$, carbogen (95% ${\mathrm{O}}_2$ and 5% ${\mathrm{CO}}_2$), room air, and ${\mathrm{N}}_2$. The table indicates the techniques that have been used to monitor the hemodynamic changes (RBF, renal blood flow; LSCI, laser speckle contrast imaging; and SDF, sidestream dark-field imaging). The graph represents the hemodynamic changes as measured by the arterial RBF probe [RBF (ml/min)].
