Which of the following is a sign of airway obstruction?

A sign of airway obstruction is indicated when a casualty makes snoring or gurgling sounds. These sounds typically occur when there is partial obstruction of the airway, often due to the tongue or other tissues. When the airway is compromised, the flow of air can be disrupted, causing abnormal noises as the casualty attempts to breathe. This is a clear indicator that immediate attention is required to secure the airway to ensure proper ventilation and oxygenation.

In contrast, situations where a casualty is alert and talking, showing no signs of distress, or breathing normally would suggest that their airway is clear and functioning properly. In those scenarios, there is generally no indication of an obstruction, as the individual is able to communicate effectively and maintain a regular breathing pattern. Recognizing abnormal sounds like snoring or gurgling is crucial in the early identification of airway issues during tactical situations, allowing for timely intervention.
