High-pitched sounds are indicative of complete choking because they suggest that air is not flowing freely through the airway. When a person is experiencing complete choking, the airway is obstructed, which prevents normal breathing and can lead to the production of high-pitched noises as the person struggles to breathe. This is a critical symptom to recognize, as it signifies a severe airway obstruction that requires immediate intervention.

In contrast, the ability to speak would indicate that the airway is not completely blocked, as a person must have enough air passage to form words. Pale skin with anxiety may suggest distress but is not specific enough to indicate complete choking. Similarly, forceful coughing typically indicates that the person still has some airflow and is able to attempt to clear the obstruction themselves. Recognizing the signs of complete choking is crucial for prompt and effective first aid response to prevent respiratory distress or failure.
