Figure 2: The recovery of the oxygen saturation of the control extremity as a function of time.A small decrease in oxygen saturation similar to that seen in the operative extremity is demonstrated, but it is less pronounced and occurs slightly later at about 8 minutes and recovered at approximately 12 minutes.This decrease in oxygen saturation was dampened in the reduced pressure group (group II), as the saturation dropped an average of 2 minutes later and by only 1-2 mmHg.This difference did not reach statistical significance.
