In CPR, what should be the depth of compressions for children?

For performing CPR on children, the recommended depth of compressions is approximately one-third the depth of the chest. This guideline is rooted in the anatomical characteristics of children's bodies, as their chests are not as deep as those of adults. For pediatric patients, this means compressing the chest to about 1.5 to 2 inches, which aligns with the one-third depth principle. This depth is crucial because it allows for effective circulation during cardiac arrest, helping to maintain blood flow to vital organs.

Other options may suggest specific measurements that do not accurately account for the differing anatomy of children compared to adults, making one-third of the chest the most appropriate and effective guideline for delivering compressions in pediatric CPR.
