Figure 1. The oxyhaemoglobin dissociation curve illustrates the relationship between SaO2/SpO2 and PaO2.
Figure 2. Range of oxygenation states that can be assessed with SaO2/SpO2, ORi, and PaO2. SaO2/SpO2 can assess hypoxia and normoxia, PaO2 can assess all ranges of oxygenation, and SpO2 with ORi provides real-time visibility from hypoxia to the moderate hyperoxic state.
Figure 3. ORi levels drop prior to “30% FiO2” period and “intubation” period, and minutes before the SpO2 drop. ORi then rises during re-oxygenation.
