Carbon Monoxide Poisoning
This oral boards case is appropriate for all emergency medicine learners (residents, interns, and medical students).
Carbon monoxide (CO) is a colorless and odorless gas that typically results from combustion. It binds hemoglobin, dissociating oxygen, causing headache, weakness, confusion and possible seizure or coma. Pulse oxygen levels may be falsely elevated. Practitioners should maintain a high index of suspicion for carbon monoxide poisoning. If caught early CO poisoning is reversible with oxygen or hyperbaric oxygen therapy.
By the end of this oral boards case, the learner will: 1) demonstrate ability to evaluate a patient with altered mental status and discuss the differential diagnosis of a patient with altered mental status and weakness, 2) recognize the signs and symptoms of carbon monoxide poisoning, 3) demonstrate the ability to manage treatment of a patient with carbon monoxide poisoning.
