How should ventilation be delivered to avoid hyperventilation during pediatric CPR?

• A. Large tidal volumes.
• B. Gentle breaths with adequate chest rise and avoid large tidal volumes; avoid excessive ventilation.
• C. No ventilation.
• D. Continuous rapid breaths.

Answer: (B)

The main idea is to ventilate during pediatric CPR in a gentle, controlled way that achieves visible chest rise without overinflating the lungs. Delivering large tidal volumes or forcing air in too quickly raises intrathoracic pressure, which can reduce venous return to the heart and lower perfusion during compressions. It can also cause gastric inflation, increasing the risk of vomiting and aspiration and wasting time pausing compressions. Therefore, the best approach is to give breaths that produce adequate chest rise but avoid large volumes or rapid, forceful ventilation—and refrain from excessive ventilation overall. In practice, this means using gentle breaths at a rate that maintains continuous chest compressions and minimizes interruptions, ensuring each breath contributes to visible chest rise without overdistending the lungs. If chest rise isn’t seen, adjust airway/technique rather than increasing force or volume.
