Where should first aid responders position their hands for chest compressions when using two hands on a child?

Positioning the hands in the center of the chest is the correct approach for giving chest compressions when performing CPR on a child. This positioning allows for effective compression of the heart, ensuring that blood is circulated efficiently to vital organs. Proper hand placement maximizes the compressive force and provides the best chance of restoring blood flow during cardiac arrest.

When the hands are positioned in the center of the chest, typically at the lower half of the sternum, it aligns with the anatomical location of the heart. This is crucial because it ensures that the compressions are both effective and safe.

In contrast, placing the hands in other areas, such as the abdomen or lower rib cage, would not target the heart effectively and could lead to ineffective compressions, failing to provide adequate circulation. Additionally, positioning hands at the sides of the abdomen is not appropriate as it would completely miss the area where compressions should be applied. Proper technique is vital in CPR situations to ensure the best outcomes.
