A firefighter rescued man with significant respiratory distress shows brassy cough and singed nasal hairs. The most immediate threat is?

• A. Hypothermia.
• B. Airway swelling.
• C. Severe burns.
• D. Severe infection.

Answer: (B)

Inhalation injuries from smoke can rapidly irritate and inflame the lining of the airway. Signs like brassy cough and singed nasal hairs point to exposure to hot gases and airway injury. The immediate danger is swelling of the airway tissues (edema) that can develop within minutes to hours and quickly narrow or block the airway, leading to severe hypoxia or respiratory failure. That acute risk outpaces other burn-related problems because if the airway closes, oxygen delivery stops and death can occur very quickly.

Hypothermia, severe burns, and infection become concerns as the patient stabilizes or worsens over time, but they do not pose the same immediate threat to breathing as rapidly progressing airway edema in inhalation injuries. Therefore, securing and protecting the airway promptly is the priority in this scenario.
