When performing CPR on an infant without an advanced airway, how many compressions should be performed for every 2 ventilations?

In the context of CPR for infants who do not have an advanced airway, the correct ratio of compressions to ventilations is 15 compressions followed by 2 ventilations. This specific ratio is designed for situations where there are two rescuers performing CPR on an infant. It is critical to provide adequate chest compressions to maintain blood circulation while delivering ventilations to ensure the infant receives oxygen.

During this process, the emphasis is on maintaining a higher ratio of compressions to ventilations to promote effective blood flow and oxygen delivery. Research and guidelines suggest that this approach maximizes the chances of survival until further medical help can be provided.

The other ratios presented do not align with current CPR guidelines for infants, as they either provide too few compressions for the necessary blood flow or too many in relation to the needed ventilations.
