When performing chest compressions on a child, how many hands should be used?

Using one or two hands for chest compressions on a child is appropriate because the decision is based on the size and age of the child. For younger or smaller children, one hand may provide sufficient force while allowing the rescuer to maintain proper technique and avoid injury. If the child is larger or older, using two hands can ensure that adequate depth and rate of compressions are achieved. This adaptability is crucial in effectively delivering high-quality CPR, as it allows the lifeguard or rescuer to modulate their approach to meet the physical needs of the child in distress.

Using only one hand regardless of size may not provide adequate compression depth for larger children, while always using two hands could lead to unnecessary force or an inability to maintain effectiveness with smaller children. Specialized equipment is not necessary for performing basic life-saving measures like chest compressions in this scenario, allowing rescuers to act promptly and effectively without waiting for additional tools. Thus, the correct response emphasizes the importance of assessing the individual child's needs when determining the technique for CPR.
