Which scenario would best indicate a mechanical airway obstruction?

• A. A foreign object is present in the airway
• B. The tongue blocks the airway due to swelling
• C. The airway is blocked by swollen throat tissues
• D. The airway is blocked by saliva

Answer: (A)

Mechanical airway obstruction comes from a physical blockage in the airway. A foreign object in the airway is the clearest example because you can see or feel the actual blockage and it often requires immediate removal. Swelling of the tongue or throat tissues narrows the passage due to edema, which is obstruction by tissue enlargement rather than a discrete object. Saliva blockage is due to secretions, not a solid object blocking the airway. So the scenario with a visible foreign object best represents a mechanical obstruction.
