How many ventilations should be provided to children and infants without advanced airways after each round of compressions during CPR?

In Basic Life Support (BLS) for children and infants without advanced airways, the protocol specifies that rescuers should provide 2 ventilations after every 30 compressions during cardiopulmonary resuscitation (CPR). This 2-ventilation sequence is essential as it helps to ensure that the child or infant receives sufficient oxygenation following the chest compressions, which are crucial for maintaining blood circulation.

The rationale behind administering two ventilations is to strike a balance between effective chest compressions and respiratory support. Since children and infants have a higher likelihood of respiratory issues leading to cardiac arrest, delivering these two breaths helps address the underlying problem while still maintaining circulation through continuous compressions. Properly timed and delivered breaths can improve chances of survival and recovery from cardiac arrest.

It's important to remember that the emphasis is not just on breathing but also on the quality and timing of the ventilations to maximize their effectiveness while continuing effective chest compressions.
