Which statement correctly describes treatment goals for CO poisoning?

Which statement correctly describes treatment goals for CO poisoning?

• A. Administration of 100% oxygen by mask or hyperbaric chamber until carboxyhemoglobin levels normalize.
• B. Reduction of fever as the primary goal.
• C. Only symptomatic care without oxygen.
• D. Immediate surgical intervention.

Answer: (A)

In carbon monoxide poisoning, the priority is quickly restoring oxygen delivery by displacing CO from hemoglobin. CO binds strongly to hemoglobin, forming carboxyhemoglobin and preventing oxygen from reaching tissues. Providing 100% oxygen, typically by a nonrebreather mask, speeds up the replacement of CO with oxygen, reducing the carboxyhemoglobin level and improving tissue oxygenation. In more severe cases, or in certain situations such as suspected neurological involvement or pregnancy, hyperbaric oxygen can further accelerate CO elimination and lessen the risk of delayed neurologic effects. Reducing fever or giving only symptomatic care without addressing the underlying hypoxia won’t fix the impaired oxygen delivery. Immediate surgical intervention isn’t relevant to CO poisoning. The essential goal is to eliminate CO promptly and reoxygenate the tissues.
