How deep should compressions be when performing CPR on a child aged 5-12 years?

When performing CPR on a child aged 5 to 12 years, the recommended depth for chest compressions is about 2 inches. This depth is crucial because it allows for effective compression of the chest to create sufficient blood flow during cardiac arrest.

The goal of chest compressions during CPR is to maintain blood circulation to vital organs by creating pressure in the chest cavity that forces blood out of the heart and through the body. Research and guidelines from recognized organizations, including the American Heart Association, support this compression depth as optimal for effective resuscitation in this age range.

Compressions that are too shallow may not generate adequate blood flow, while those that are too deep can potentially cause injury to the child's ribcage or internal organs. Therefore, adhering to the 2-inch guideline balances the need for effective blood flow while minimizing the risk of harm.
