What is considered a normal oxygen saturation level in the NICU?

• A. <85%
• B. >90%
• C. <90%
• D. <95%

Answer: (B)

SpO2 in the NICU is monitored continuously, and the goal is to keep oxygenation adequate without causing oxygen toxicity. A normal level for infants in the NICU is generally above 90%, which indicates sufficient oxygen delivery to tissues. Readings below 90% signal hypoxemia and prompt adjustments in support. While exact targets can vary by gestational age and condition, staying above 90% is the standard baseline for normal oxygenation. Very high saturations can carry risks in some preterm infants, so clinicians also avoid prolonged saturations in the mid-to-high 90s, but the question’s normal range is best represented by greater than 90%.
