What is the correct chest compression depth for a child?

At least one quarter the depth of the chest
At least one third the depth of the chest, or approximately 5 cm (2 inches)
At least half the depth of the chest
At least 7 cm (3 inches)

The correct answer is: At least one third the depth of the chest, or approximately 5 cm (2 inches)

The appropriate chest compression depth for a child during cardiopulmonary resuscitation (CPR) is indeed at least one third the depth of the chest, which translates to approximately 5 cm (2 inches). This depth is essential to ensure effective circulation and delivery of oxygenated blood to vital organs during a cardiac arrest. The guideline of one third is informed by studies indicating that this depth provides sufficient force to compress the heart and generate blood flow while minimizing the risk of injury to the child's ribs or other structures. Compressions that are too shallow may not produce adequate blood flow, decreasing the chances of survival and recovery. Therefore, it is vital to adhere to this depth standard, as it has been established as the most effective for promoting circulation in children. This guideline helps ensure that rescuers can provide high-quality CPR and optimize the outcomes for pediatric patients requiring resuscitation.
