For a smaller child, which technique may be used for high-quality chest compressions?

The one-hand technique is appropriate for smaller children when performing high-quality chest compressions. This technique is effective because it allows the rescuer to maintain the correct hand positioning and depth of compressions while being more suited to the size and physical structure of a smaller child's chest.

Using one hand allows the rescuer to apply adequate force without risking injury to the child, especially considering the smaller chest size and anatomical differences compared to adults. This technique helps ensure that compressions are both effective and safe, essential for promoting blood circulation during a cardiac emergency.

In contrast, the two-hands technique may be more appropriate for larger children or adults where applying more force is necessary. The two-finger technique is typically employed for infants rather than children, while the chest thrust technique is not a primary method for cardiac arrest compressions in children but is used for relieving choking. Therefore, the one-hand technique is a balanced approach for delivering effective chest compressions in smaller children.
