SpO2 reading of 93% is considered?

• A. Normal
• B. Elevated
• C. Abnormal
• D. Unknown

Answer: (C)

SpO2 shows how much oxygen bound to hemoglobin is in the blood. In healthy people, it’s normally about 95–100%. A reading of 93% is below that normal range, so it’s considered abnormal. This indicates reduced oxygenation that should be evaluated in the context of the patient’s breathing, symptoms, and any orders for supplemental oxygen or further assessment. Keep in mind that readings can be affected by factors like nail polish, cold or poorly perfused fingers, or motion, so interpret the value alongside the overall clinical picture.
