Appendix
Relation between Oxygen Saturation and Partial Pressure
The relation between oxygen saturation (SpO
2
) and oxygen
partial pressure (PaO
2
) is shown in the graph below. SpO
2
is the
oxygen saturation as measured by pulse oximeters.
■
Oxygen Saturation vs. Oxygen Partial Pressure
The curve of the above graph may shift to the right or left according to
the pH of the blood or the body temperature.
•
Shift to right: acidosis, high body temperature
•
Shift to left: alkalosis, low body temperature
