In pediatric stroke, what oxygen delivery method is recommended?

• A. 2 L via nasal cannula
• B. Non-rebreather mask 15 L
• C. Room air
• D. 6 L via NC

Answer: (A)

In acute pediatric stroke, the goal is to keep brain tissue well-oxygenated without giving more oxygen than needed. Start with the lowest level of supplemental oxygen that maintains a safe oxygen saturation (typically keeping SpO2 around 94% or higher). A nasal cannula at about 2 liters per minute provides a gentle, modest increase in oxygen delivery, enough to correct mild hypoxemia while remaining comfortable and easy to titrate as the child's status changes. It avoids the risks of delivering very high oxygen concentrations, which isn’t necessary unless there is significant hypoxemia.

Higher-flow options, like a higher-rate nasal cannula or a non-rebreather mask at 15 L, deliver much more oxygen and are reserved for more severe respiratory compromise; they’re not first-line for routine pediatric stroke care. Room air would be appropriate only if the child’s oxygen saturation is already adequate, but in an acute stroke scenario you start with a cautious, small step up to ensure sufficient oxygen delivery. If the SpO2 remains low, you would escalate carefully to adjust.

So, starting with 2 L per minute via nasal cannula aligns with maintaining adequate oxygenation with the simplest, least invasive approach.
