Baseline tissue oxygenation (${\mathrm{StO}}_2$) from both venous (o) and arterial (*) occlusion measurements. Error bars represent the standard deviation of ${\mathrm{StO}}_2$ from every time point acquired during baseline. Each measurement for venous occlusions for each subject was not acquired from the same precise tissue location as for the arterial occlusion for the same subject.
