What do the results mean?
If your blood oxygen level results are not normal, it may mean you:
Are not taking in enough oxygen
Are not getting rid of enough carbon dioxide
Have an imbalance in your acid-base levels
These conditions can be signs of a lung or kidney disease. The test can't diagnose specific diseases, but if your results are not normal, your health care provider will order more tests to confirm or rule out a diagnosis. If you have questions about your results, talk to your health care provider.
