Which compression technique should be used for a small child like Maggie?

For a small child, the appropriate compression technique is one that ensures effective chest compressions while minimizing the risk of injury. The one hand on top of the other technique is suitable for infants and small children since it allows the rescuer to generate enough force without applying excessive pressure that might occur with techniques better suited for older children or adults.

This technique enables the rescuer to position themselves properly and maintain a stable posture during compressions, which is critical for maintaining consistent depth and rate necessary for effective cardiopulmonary resuscitation (CPR). It also helps in providing compressions that are proportional to the child's body size and anatomical characteristics, addressing the specific needs during resuscitation.

The other options involve techniques that may be more applicable for either infants or larger children, but do not align as closely with the recommended approach for small children like Maggie, thereby making this technique the most suitable for the scenario presented.
