What is the depth of chest compressions recommended for children?

The recommended depth of chest compressions for children is about 1.5 inches (4 cm). This guideline is based on research indicating that this depth is effective in generating adequate blood flow during cardiopulmonary resuscitation (CPR). The goal during compressions is to ensure that there is enough force applied to the chest to allow for effective circulation of blood, particularly in an emergency cardiac situation.

In children, the chest is smaller and more delicate than in adults, which is why the depth of compression is shallower compared to adult CPR guidelines. Ensuring the correct depth is crucial, as compressions that are too shallow may not be effective, while those that are too deep could cause injury to the child's developing body. Therefore, adhering to the recommended depth of around 1.5 inches helps maximize the effectiveness of CPR while minimizing the risk of harm.
