What is the proper depth of chest compressions for a child in cardiac arrest?

For a child in cardiac arrest, the proper depth of chest compressions is to compress the chest at least one third the depth of the chest. This recommendation is based on guidelines from leading health organizations, which emphasize the importance of effective chest compressions to maintain circulation during cardiopulmonary resuscitation (CPR).

Compressing to at least one third of the chest depth ensures that enough pressure is applied to create adequate blood flow during the compressions. In children, the chest is more compliant and shallower compared to adults, so it is essential to achieve this specific depth to overcome the natural elasticity of the chest wall and to provide sufficient myocardial perfusion.

Using this depth also aligns with best practices that have been studied and shown to improve the outcome for children experiencing cardiac arrest. This allows for effective ventilation and perfusion, improving the chances of a successful resuscitation.

While other suggested depths may seem close to ideal or appropriate, they do not meet the necessary parameters for effective compression in pediatric patients.
