This is a test which roughly monitors the oxygen saturation in the blood. The SaO2 is the ratio of oxygenated hemoglobin (red blood cells) to the amount of hemoglobin available. For example, an SaO2 of 95% means that 95% of the total hemoglobin attachments have oxygen attached to them. This will be a good approximation of how much oxygen is being carried in the blood. If more accurate determinations or more information is required, arterial blood gasses may be drawn.
PREPARATION FOR TEST
No preparation or fasting is necessary.
Greater than or equal to 95%
Possible critical values: less than or equal to 75%
Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
MEANING OF TEST
Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.
