What modifications are made for CPR on a child (1 year to puberty)?

The recommended technique for cardiopulmonary resuscitation (CPR) on a child, specifically from around 1 year old to puberty, involves using one hand for chest compressions at a rate of 100 to 120 compressions per minute. This approach is designed to provide effective circulation while considering the smaller size and more fragile body structure of children compared to adults.

Using one hand allows for better control and minimizes the risk of causing injury to the child, while the recommended compression rate of 100 to 120 per minute is crucial for maintaining adequate blood flow and oxygenation to vital organs. Performing compressions at this specific rate helps to optimize the chances of survival until advanced medical help arrives.

In contrast, using two hands, performing only rescue breaths, or conducting compressions without rescue breaths do not align with the established guidelines for child CPR, which emphasize the importance of proper technique and the combination of compressions and breaths in certain circumstances.
