Figure 3

Differences in the pulse oximeters’ SpO2 measurements among SaO2 categories. Three SaO2 categories were established (SaO2 < 94%, 94% ≤ SaO2 < 98%, SaO2 ≥ 98%). The vertical axis represents SpO2 – SaO2, the horizontal axis represents Nihon Kohden SpO2 and Masimo SpO2 for each of the three groups. There were significant differences in the groups with SaO2 ≥ 94%. However, there was no significant difference in the SaO2 < 94% group. *: P < 0.005.
