At what chest compression depth should an infant be treated during CPR?

The appropriate chest compression depth for infants during CPR is 1.5 inches. This depth is crucial because it ensures that sufficient pressure is applied to the chest to promote effective blood flow during compressions. The recommended depth allows for adequate compression of the heart, which is located centrally in the thoracic cavity and is relatively small in infants.

Using the correct depth helps to achieve optimal hemodynamic responses, improving the chances of restoring circulation and increasing the likelihood of survival in cases of cardiac arrest. It's essential for healthcare providers to adhere to these guidelines, as too shallow compressions may not generate enough blood flow, while compressions that are too deep can cause injury to the infant’s ribs and underlying organs.
