Question

what is the correct chest compression depth for an infant?
at least one fourth the depth of the chest, or about 1 inch
at least one third the depth of the chest, or about 1 - 1/2 inches
at least one third the depth of the chest, or about 2 inches
at least one half the depth of the chest, or about 2 - 1/2 inches

Explanation:

According to CPR guidelines, for an infant, the correct chest - compression depth is at least one - third the depth of the chest, or about 1.5 inches (1 - 1/2 inches). This depth is sufficient to effectively circulate blood while minimizing the risk of causing excessive injury to the infant's relatively fragile chest structure.

Answer:

At least one third the depth of the chest, or about 1 - 1/2 inches.
