Which signs can indicate an obstruction of the airway?

Signs of an obstructed airway can manifest in various abnormal sounds during breathing. When an airway obstruction occurs, air may struggle to pass through, causing sounds such as wheezing, stridor, or a gurgling noise, depending on the level and location of the obstruction. These abnormal sounds are critical indicators for health professionals to assess the severity of the situation.

In contrast, normal breath sounds suggest that the airway is clear and functioning properly. Slight coughing may indicate a minor irritation or something stuck in the throat, but it does not alone suggest a severe obstruction. Clear speech generally implies that the airway is unobstructed, as a person with a significant obstruction would likely struggle to talk or produce coherent sounds. Therefore, the presence of abnormal sounds during respiration is a key sign of potential airway obstruction, making it the most relevant indicator among the options provided.
