What is a common treatment for a patient suffering from carbon monoxide poisoning?

• A. Administer high-flow oxygen
• B. Provide mechanical ventilatory support
• C. Initiate aggressive fluid resuscitation
• D. Use activated charcoal

Answer: (A)

Administering high-flow oxygen is the standard treatment for carbon monoxide poisoning. This is because carbon monoxide (CO) binds to hemoglobin much more effectively than oxygen, forming carboxyhemoglobin and reducing the blood's capacity to carry oxygen to tissues. By providing high-flow oxygen, you help to displace CO from hemoglobin and increase the amount of oxygen available in the blood, which can significantly improve symptoms and reduce the risk of long-term complications associated with hypoxia.

In cases of severe carbon monoxide exposure, hyperbaric oxygen therapy may also be utilized, but high-flow oxygen therapy is the immediate, first-line intervention that is accessible in most emergency settings. Other treatments, such as mechanical ventilatory support or fluid resuscitation, are not specific for treating carbon monoxide poisoning and do not directly address the underlying problem of CO binding to hemoglobin. Activated charcoal is also irrelevant in this scenario, as it is used for certain types of ingested poisons, not for inhaled gases like carbon monoxide.
