Which of the following may indicate a person is choking? Select all that apply.

When a person is choking, certain signs can indicate that their airway is blocked. The presence of surprise on a person’s face, as suggested in the selected choice, can reflect their sudden realization of being unable to breathe properly, which is linked to choking. However, there are other common signs that may be more indicative of a choking situation.

Coughing is often a reflex action the body takes to clear the airway, and while effective in some cases, it can sometimes occur even when a person isn't choking. High-pitched squeaking noises typically signal that air is struggling to pass through a partially obstructed airway. Furthermore, pointing to their throat is a direct communication signal that someone may use to express distress due to choking.

Recognizing these various signs is crucial for providing timely help and potentially saving a life in an emergency scenario.
