What is the correct approach for bag-mask ventilation in an apneic 3-year-old child?

The correct approach for bag-mask ventilation in an apneic 3-year-old child is delivering each breath over 1 second until the chest rises visibly. This method ensures that the ventilations are both efficient and gentle enough to avoid causing barotrauma or other potential injuries to the child’s lungs.

When using bag-mask ventilation, it is crucial to synchronize the breath delivery with the child's needs, especially since children have a smaller tidal volume compared to adults. Aiming for a visible rise of the chest indicates that air is being effectively delivered into the lungs, which is key for ensuring proper ventilation.

In pediatric patients, the airway and lung mechanics are different from those in adults, and the approach should be delicate to protect the child’s airway and prevent any adverse effects. Focusing on a smooth, steady delivery of breaths while monitoring for the rise and fall of the chest is crucial, making this method the safest and most effective way to provide ventilation in this age group.

Factors such as hyperextending the head can compromise the airway in small children, while consistently delivering a specific tidal volume like 400 mL is often inappropriate due to their smaller lung capacity. Hyperventilation can lead to additional complications such as decreased cardiac output and can also
