How deep should compressions be for a child during CPR?

For performing CPR on a child, compressions should be about 1.5 inches (4 cm) deep. This depth is recommended because it is sufficiently effective in creating blood flow during cardiac arrest while also being safe for the child's smaller chest size. The guideline emphasizes achieving adequate depth to facilitate the necessary circulation without causing injury to the underlying organs, which is particularly crucial in younger patients whose bodies are still developing.

The other depths mentioned may not align with appropriate guidelines for pediatric CPR. For instance, compressions that are too shallow might not adequately circulate blood, leading to ineffective resuscitation. Conversely, compressions that are too deep could pose a risk of injury, as children have more delicate anatomical structures compared to adults. Thus, maintaining a depth of approximately 1.5 inches strikes a crucial balance between efficacy and safety.
