Final answer:
If an infant isn't breathing normally but has a pulse, the proper action is to provide rescue breaths at a rate of one breath every three to five seconds until they breathe normally, help arrives, or an AED is ready.
Step-by-step explanation:
If an infant isn't breathing normally but has a pulse, the correct course of action is to provide rescue breaths since the heart is still beating. According to current guidelines, for an infant who isn't breathing normally but has a pulse, you should give rescue breaths at a rate of one breath every three to five seconds (not too quickly or too slowly). You should continue doing this until the infant begins to breathe normally on their own, help arrives, or an AED (Automated External Defibrillator) is ready to use.
It's essential to remain calm and focus on the task of providing rescue breaths at the correct rhythm. Keep in mind that proper technique is crucial for effective rescue breathing. Make sure to seal the infant's nose and mouth correctly and deliver just enough air to make the chest rise with each breath.
