How many cycles of rescue breathing should you provide for a child?

The correct number of cycles of rescue breathing for a child is typically based on the recommended guidelines for pediatric resuscitation. In the context of rescue breathing, the appropriate approach for children generally involves providing a ratio of breaths to chest compressions.

If we take the recommended guidelines into account, it stipulates that for every 30 compressions, you should deliver 2 rescue breaths. This cycle is repeated continuously. Therefore, if you were to perform back-to-back cycles in a resuscitation scenario, after one full cycle of 30 compressions followed by 2 breaths, you would complete the initial cycle within the blink of minutes.

When the given options lean towards a higher number of cycles, particularly 40 cycles, it reflects an understanding that multiple rounds of rescue breathing and compressions may be revisited in a prolonged resuscitation effort.

Using the structure of the question, while it hints at the number of cycles, the most relevant information within the standard practice is that 2 rescue breaths should follow every 30 compressions, which can lead to a successful resuscitation. Thus, understanding that 40 cycles align closely with the continuous and repetitive process indicative of CPR not extending beyond a reasonable time frame or effort could clarify that while
