The correct approach for CPR on an infant without an advanced airway involves providing rescue breaths after a series of compressions. Specifically, the recommended ratio is 15 chest compressions followed by 2 breaths. This method ensures that the infant receives sufficient oxygen while also maintaining effective circulation through compressions.

In this context, 15 compressions followed by 2 ventilations is based on the need to prioritize both blood circulation and oxygenation in a high-quality CPR sequence. This ratio is particularly important when dealing with infants as their physiology differs from adults, making proper technique crucial for their survival in cardiac emergencies.

The other ratios mentioned do not align with current CPR guidelines for infants, which emphasizes the need to provide adequate compressions and ventilations to enhance the chances of successful resuscitation. By focusing on the 15:2 ratio, rescuers can deliver the most effective care in critical situations.
