What is the appropriate first action for an unresponsive 3-month-old baby who is gasping?

In a situation where an unresponsive 3-month-old baby is gasping, the most appropriate first action is to start conventional CPR. Gasping is an indication of inadequate breathing and could signify a critical emergency situation. For infants, when facing an unresponsive state, immediate CPR is essential to provide the necessary circulation and oxygenation that the baby is not receiving.

Starting CPR involves a series of specific steps designed to optimize the chances of survival in a non-breathing, unresponsive infant. This includes initiating compressions and breaths in a cautious and effective manner tailored to the anatomical considerations of a young child.

While other actions might be relevant in different scenarios, such as checking for a pulse, administering oxygen, or providing back blows, these options may not be the priority when the infant is unresponsive and not breathing adequately. Promptly initiating CPR provides immediate support for the critical functions necessary to sustain life.
