What is the standard cycle of CPR compressions and breaths for a child?

The standard cycle of CPR for a child is 30 compressions followed by 2 breaths. This ratio was established to provide effective chest compressions while also ensuring adequate ventilations. The primary goal of CPR is to maintain blood circulation and oxygenation until advanced medical help can be provided.

By administering 30 compressions, the rescuer aims to keep blood flowing to vital organs, especially the heart and brain. Following this with 2 rescue breaths allows for oxygen to be delivered to the lungs, which is crucial for sustaining life in cases of respiratory or cardiac arrest. This compression-to-breath ratio balances the need for manual circulation with the importance of reintroducing oxygen to the body, making it an effective approach to managing a child in cardiac arrest.

The alternative rhythms presented in the other choices are not in accordance with current BLS guidelines and would not provide the optimal balance needed for effective resuscitation in children.
