What is the typical ratio for child rescue breathing?

The typical ratio for child rescue breathing is indeed one breath every 3 seconds. This guideline is based on the physiological needs of a child with respect to oxygenation. For children who are not breathing or are experiencing respiratory failure, it's critical to provide breaths at a rate that ensures adequate oxygen is delivered without overwhelming their lungs.

Administering a breath every 3 seconds allows for a sufficient amount of time for the lungs to expand, facilitating proper gas exchange and helping to restore the child’s normal breathing patterns. It also aligns with pediatric resuscitation standards, emphasizing the importance of providing oxygen efficiently while minimizing potential complications such as hyperventilation.

This correct approach ensures that the child receives the necessary support in a critical situation while adhering to established protocols designed to maximize safety and effectiveness during emergency response.
