How deep should compressions be administered on a child?

The recommended depth for chest compressions on a child is one-third the depth of the chest. This guideline is essential as it ensures that the compressions are adequate to generate enough blood flow during cardiopulmonary resuscitation (CPR). When compressions are applied to this depth, it allows for appropriate cardiac output while minimizing the risk of injury to the child's developing ribcage.

This approach strikes a balance between being effective enough to circulate blood efficiently while still considering the anatomical differences of a child's body compared to that of an adult. Understanding the child's anatomy is crucial for performing CPR effectively, as too shallow compressions may not create sufficient blood flow, and too deep compressions could potentially cause harm.

By focusing on this one-third rule, first responders can be confident they are providing appropriate care in a life-threatening situation.
