Figure 2From: Assessment of tissue oxygen saturation during a vascular occlusion test using near-infrared spectroscopy: the role of probe spacing and measurement site studied in healthy volunteersTissue oxygen saturation at baseline and after ischemia, and the corresponding downslopes. (a) Measured tissue oxygen saturation (StO2) baseline values and minima after 3 minutes of ischemia. (b) Corresponding StO2 downslopes (right). ns = not significant (P > 0.05), **P < 0.01, ***P < 0.001. F, forearm; T, thenar.Back to article page
