How is CPR performed on an infant or child?

Performing CPR on an infant or child follows specific guidelines designed to maximize the effectiveness of the procedure while minimizing potential harm. The correct choice involves a ratio of 30 compressions to 2 breaths, which aligns with current resuscitation protocols for children. This ratio is intended to maintain circulation to vital organs while also providing necessary oxygen through breaths.

In the context of performing CPR on a child, maintaining a higher frequency of chest compressions (30 in this case) is critical because it helps to ensure that there is sufficient blood flow to vital organs like the heart and brain until emergency services arrive or the child shows signs of recovery. The 2 breaths following every 30 compressions facilitate oxygenation of the lungs, ensuring that the child receives adequate airflow, which is essential for effective resuscitation.

The other options do not reflect the recommended guidelines for CPR on children as effectively. The specific ratio of compressions to breaths is designed to be effective for providing immediate life support, highlighting the importance of following established protocols in emergency situations.
