How would you identify a person with partially blocked airway?

A person with a partially blocked airway may exhibit signs such as difficulty breathing, wheezing, or coughing. They might also display increased effort in breathing, with noticeable use of accessory muscles, and a feeling of anxiety or panic. Additionally, their skin may appear pale or bluish, particularly around the lips and fingertips. If the person can speak or make sounds, the airway may not be completely obstructed, but they still require immediate attention.
