What could be a sign that a choking victim cannot breathe?

A choking victim who cannot breathe is often unable to respond verbally, which indicates a significant blockage in their airway. When someone is choking, if their airway is obstructed, they lack the ability to get enough air in or push air out to create sound. This can lead to a dire situation where they cannot communicate or call for help.

In addition, while dizziness might be a symptom of various conditions, it does not specifically indicate the inability to breathe. Signs like turning red can occur due to increased effort to breathe or strain but are not definitive indicators of the inability to breathe either. The inability to talk directly correlates with the severity of an airway obstruction, making the inability to respond verbally a critical sign of a choking emergency.
