Fig. 5

Individual absolute and median rSO2 changes during resaturation #1 (a, b) and #2 (c, d). Absolute changes in SpO2, representing global saturation, are shown for comparison. Median absolute change in rSO2 reported by INVOS during resaturation #1 was significantly greater than that of EQUANOX. Although FORE-SIGHT reported a smaller median absolute change during resaturation #1 and #2 compared with INVOS, the differences were not statistically significant (two-tailed Wilcoxon Signed-Rank test for paired samples). Data are missing for one INVOX/EQUANOX subject in graph C. *Indicates statistical significance
