Fig. 4

Individual absolute and median rSO2 changes during desaturation #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 desaturation #1 and #2 were significantly greater than that of EQUANOX. Although FORE-SIGHT reported a smaller median absolute change during desaturation #1 and #2 compared with INVOS, the differences were not statistically significant (two-tailed Wilcoxon Signed-Rank test for paired samples). *Indicates statistical significance
