When using a bag-mask device to ventilate a child, how long should each breath be delivered?

Delivering each breath for 1 second when using a bag-mask device to ventilate a child is important for several reasons. This duration balances the need for adequate ventilation without causing excessive pressure or volume to the lungs, which can lead to complications such as barotrauma or gastric inflation.

In pediatric patients, the respiratory system is more sensitive than that of adults, and administering breaths that are too rapid or too forceful can be harmful. A breath duration of 1 second allows time for the chest to rise appropriately, indicating effective ventilation, while ensuring that the child receives sufficient oxygen without overwhelming their respiratory tract.

Additionally, this timing aligns with established BLS guidelines, which emphasize the importance of achieving a visible chest rise while maintaining a rhythm that does not interfere with the natural respiratory pauses the child might have. This approach promotes a better outcome and aligns with safe emergency practices.
