A SpO2 reading of 93% would be interpreted as?

• A. Normal value
• B. Severe hypoxemia
• C. Moderate improvement
• D. Hypoxemia in most scenarios

Answer: (D)

SpO2 shows how much oxygen your blood is carrying in the form of hemoglobin-bound oxygen. Normal is typically about 95–100%. A reading of 93% is below normal, so in most clinical situations it represents hypoxemia. It’s not a normal value, and it isn’t a small improvement from a higher reading, but it’s also not in the range of severe hypoxemia (which is usually much lower, often 80% or below). Remember that some patients with chronic lung disease may have lower baseline saturations, so context matters. Still, 93% generally signals reduced oxygenation and warrants clinical correlation and monitoring to determine cause and whether an intervention is needed.
