How many rescue breaths should be given after every 30 compressions for a child?

After delivering 30 chest compressions to a child during a resuscitation attempt, the proper protocol is to give two rescue breaths. This guideline stems from established CPR practices, which ensure adequate oxygenation is provided to the child after performing compressions, thereby addressing potential hypoxia.

When administering the rescue breaths, it is crucial to ensure that each breath is given over one second, with an adequate rise of the chest, indicating effective ventilation. This approach is integrated into the rhythm of CPR, where the cycles of compressions and breaths work together to restore circulation and breathing effectively.

Given that the other amounts do not align with standard CPR practices for children, they would not deliver the optimal balance of compressions and breaths necessary to support the child's physiological needs during resuscitation. Hence, two rescue breaths are emphasized to maximize the chances of successful resuscitation.
