What is the recommended oxygen strategy during pediatric resuscitation to balance tissue oxygen delivery?

• A. Keep FiO2 at 100% indefinitely
• B. Never use FiO2 above 50%
• C. Oxygen therapy is not important
• D. Optimize delivery while titrating FiO2 to target saturations

Answer: (D)

Oxygen delivery to tissues during pediatric resuscitation must be balanced: provide enough oxygen to meet metabolic needs while avoiding excess that can cause harm. Oxygen delivery depends on how much oxygen you breathe in (FiO2), how well it’s carried in the blood (saturation), and how well blood is perfusing tissues. The best approach is to optimize delivery and adjust FiO2 to reach target saturations appropriate for the child. This means you don’t keep FiO2 at 100% forever, and you don’t ignore oxygenation—yet you avoid under-supplying oxygen by using fixed, overly low levels. Start with adequate oxygen, monitor SpO2, and titrate FiO2 to stay within recommended target ranges.
