What is the correct technique for applying chest compressions on a child?

The correct technique for applying chest compressions on a child involves using both hands to compress the chest. This method is effective because it allows for a greater force to be applied during resuscitation efforts, essential when attempting to circulate blood in a child who is unresponsive and not breathing.

In this scenario, using both hands ensures that the compressions are deep enough and delivered at an adequate rate to help restore blood flow to vital organs. It's important to place the hands in the center of the chest, between the nipples, and push down hard and fast, aiming for a depth of about 1/3 to 1/2 the depth of the chest. This technique maximizes the chances of creating enough pressure to pump the heart effectively, which is critical in emergency situations.

Other methods of compressing the chest, like using only one hand, may not generate sufficient force for effective circulation. Pressing down on the abdomen would not effectively aid in cardiac function and could complicate the situation by causing airway obstruction or discomfort. Finally, using only fingers is unsuitable for children for the same reason: it does not provide the necessary force to perform CPR effectively. Hence, using both hands aligns with best practices in CPR for children.
