When should you use one hand instead of two during chest compressions on children?

Using one hand for chest compressions during CPR on children is appropriate for smaller children, typically those who are around the age of 1 to 8 years. This is due to their smaller chest size and the need for compression depth that can be effectively achieved with one hand. One-handed compressions allow for better control and proper technique, which is crucial for effectively providing life-saving measures.

In contrast, when performing CPR on an infant, specific techniques are used that may involve the thumbs or two fingers, but the focus on using one hand becomes particularly relevant for smaller children where the rescuer can easily apply the appropriate force without using two hands. For larger children or older adolescents, two hands may be necessary to ensure sufficient compression but for smaller children, one hand often suffices and provides the necessary depth and rate of compressions that are vital during CPR.
