Which option is a key treatment for carbon monoxide poisoning?

In cases of carbon monoxide poisoning, the primary treatment involves administering 100% high-flow oxygen. Carbon monoxide binds to hemoglobin more effectively than oxygen, which impairs the blood's ability to transport oxygen throughout the body. By providing high-flow oxygen, the goal is to displace carbon monoxide from hemoglobin and facilitate its elimination from the body. This treatment significantly reduces the half-life of carbon monoxide in the bloodstream and helps restore normal oxygen levels to tissues, mitigating the harmful effects of hypoxia.

The other treatment options do not directly address the acute physiological impact of carbon monoxide poisoning. Continuous intravenous medication may be useful in managing other conditions but does not tackle carbon monoxide binding. Broad-spectrum antibiotics are typically utilized for infections, which is unrelated to the treatment of carbon monoxide exposure. Bronchodilator therapy might be indicated in certain pulmonary conditions, but it does not play a role in resolving the effects of carbon monoxide poisoning, where oxygen supply is the critical issue.
