Figure 3: The difference in oxygen saturation between the study and control extremity as function of time.The reduced pressure group is represented by the blue line, and standard the red line.The operative and control saturations were slightly variable at the time of tourniquet deflation, became considerably more variable between 4 and 8 minutes, and were less divergent after the 8 minutes time point.Overall, there was no statistical significance between the oxygen saturation of the study and control extremity at any time point.
