What indicates a mild airway obstruction?

A mild airway obstruction is indicated when the victim is able to speak and is coughing. In this situation, the airway is partially blocked, but not completely obstructed, allowing for some airflow. Coughing is an effective response as it can help to dislodge the obstruction. The victim's ability to speak indicates that they still have sufficient air movement to communicate, which is a sign that the obstruction is not severe.

In contrast, other scenarios such as the victim being unconscious, bluish in color and unable to cough, or silent and struggling to breathe, suggest a more severe airway obstruction where immediate intervention would be necessary. These situations require urgent attention to clear the airway, as the victim could be at risk of complete airway failure.
