What is the most appropriate compression technique for an older child?

The most appropriate compression technique for an older child involves placing one or two hands on the lower half of the sternum while maintaining the proper depth of chest compressions. This technique is crucial because it allows for effective circulation during cardiac arrest situations, ensuring that blood is adequately pumped to vital organs.

Using one or two hands provides the necessary force for compressions while allowing for good control and precision. In older children, it is important to ensure the depth of compressions is adequate, typically at least one third of the chest's depth, which is approximately 2 inches (5 cm) for a child. Positioning the hands on the lower half of the sternum is advised as it maximizes the efficacy of the compressions and minimizes the risk of injury to the child’s ribs or internal organs.

The other techniques presented do not align with established pediatric resuscitation guidelines. For example, a back-and-forth motion with both hands can lead to ineffective compressions, as it may not provide a rhythmic and consistent pressure necessary for blood circulation. Using compression pads is not a standard practice in pediatric cardiopulmonary resuscitation (CPR), and pushing down on the abdomen would not generate the necessary compressive force on the heart, potentially leading to
