When performing CPR on a child, how should your compressions differ from adults?

When performing CPR on a child, it's crucial to adapt the technique from that used on adults to accommodate their smaller size and more fragile bodies. Compressing about 1.5 inches deep is appropriate for a child, as this depth is sufficient to generate adequate blood flow without causing injury. Using one hand is typically effective for children, allowing the rescuer to have better control and reducing the risk of applying excessive force.

This approach is guided by the principles of pediatric resuscitation, which emphasize the importance of using adequate depth and force while also being cautious about the potential for injury. The other options either involve inappropriate techniques or depths that could lead to serious injury or improper resuscitation outcomes.
