In RSV bronchiolitis, what oxygen status indicates that room air is sufficient?

• A. 90% or more on room air
• B. 95% on room air
• C. 85% on room air
• D. 100% oxygen supplementation

Answer: (A)

In RSV bronchiolitis, oxygenation is guided by pulse oximetry. If a child can maintain an oxygen saturation of 90% or higher while breathing room air, this is generally considered adequate, and supplemental oxygen is not needed. Values below 90% indicate hypoxemia and the need for oxygen support. So the statement of 90% or more on room air best indicates that room air is sufficient. A reading like 85% on room air would signal the need for oxygen, and 100% oxygen supplementation means oxygen is being provided.
