When conducting pediatric CPR, how many breaths should be given after 30 compressions for a child?

During pediatric CPR for a child, the correct practice is to provide two breaths after every 30 chest compressions. This ratio is crucial because it ensures that the child receives effective ventilations along with the necessary blood circulation from the compressions.

The rationale for giving two breaths is that it allows for adequate oxygenation of the child's lungs before continuing with further compressions. The breaths should be delivered gently, ensuring that the chest rises visibly, which indicates that air is correctly entering the lungs. This two-to-thirty compression ratio supports the fundamental principles of CPR, focusing on both circulation and respiration, which are essential for reviving someone in cardiac arrest.

In this context, the other options are incorrect as they do not align with the established CPR guidelines for children, which can differ from those for adults or infants. Specifically, giving one breath or three to four breaths would not provide the appropriate balance needed to maintain oxygen levels effectively while also ensuring proper blood circulation.
