Which signs indicate carbon monoxide poisoning, and what is the immediate EMS treatment?

• A. Headache, dizziness, confusion, nausea, fatigue; treat with high-flow 100% oxygen, monitor, and rapid transport; check CO levels if available.
• B. Rash and itching; apply topical steroids.
• C. Fever and productive cough; use antibiotics.
• D. Seizures and unconsciousness; immediate defibrillation.

Answer: (A)

Carbon monoxide poisoning presents with nonspecific symptoms from tissue hypoxia, because CO binds strongly to hemoglobin and blocks oxygen delivery to cells. The signs listed—headache, dizziness, confusion, nausea, and fatigue—fit this picture, especially in a setting where exposure may be ongoing. The essential EMS treatment is to remove the person from the exposure and provide high-flow 100% oxygen as quickly as possible, while monitoring vital signs and transporting rapidly to definitive care. If available, checking CO levels can help confirm exposure, but don’t delay treatment to obtain a reading. Other choices point to different conditions: a rash and itching suggests dermatitis; fever with a productive cough points to infection needing antibiotics; seizures or unconsciousness would require airway protection and acute cardiac management, not just defibrillation.
