In a CPR scenario, how many breaths should be given after 30 compressions for adults and children?

In a CPR scenario for adults and children, the guideline is to deliver 2 breaths after every set of 30 chest compressions. This sequence is part of the recommended chest compression and ventilation ratio in basic life support, ensuring that the victim receives adequate oxygenation while maintaining effective blood circulation through compressions.

The rationale behind providing 2 breaths is based on the need to maximize ventilation without significantly interrupting the continuous circulation provided by the compressions. This ratio effectively supports the resuscitation efforts, increases the chance of restoring a normal heart rhythm, and optimally maintains oxygen levels in the blood. It's important to remember that the breaths should be given as gentle, full breaths, ensuring that there is sufficient time for the air to enter the lungs, without prolonging the interruption of compressions.

In summary, delivering 2 breaths after 30 compressions is crucial for effective CPR in adults and children, following current resuscitation guidelines.
