A 3-year-old female choked while eating a hot dog and then became unresponsive.

Comprehensive and Detailed Explanation From Exact Extract:

According to Pediatric Basic Life Support (PBLS) guidelines by the American Heart Association (AHA), when a child becomes unresponsive due to foreign body airway obstruction (FBAO), the immediate next step is to begin chest compressions. This is done before checking the airway or giving breaths because the airway is presumed obstructed. The compressions may dislodge the object.

After 30 compressions, open the airway and check for visible objects. If none are seen, attempt rescue breaths. This protocol reflects the high risk of complete airway blockage in children with sudden collapse following a choking episode.
