Final answer:
Treatment for carbon monoxide poisoning may include hyperbaric oxygen, antidotes, and ventilatory support, with hyperbaric oxygen being particularly effective at displacing CO from hemoglobin due to increased oxygen levels in the bloodstream.
Step-by-step explanation:
Treatment of carbon monoxide poisoning may include hyperbaric oxygen, antidote for inhaled chemicals, and ventilatory support, so the correct answer is D. all of the above. Hyperbaric oxygen therapy is particularly effective because it involves an environment of increased atmospheric pressure, which allows a greater amount of oxygen to diffuse into the patient's bloodstream, in turn displacing the carbon monoxide that is tightly bound to hemoglobin. This higher concentration of oxygen enhances the process by which hemoglobin releases carbon monoxide and binds oxygen instead. Administering 100 percent oxygen is also common, accelerating the dissociation of carbon monoxide from hemoglobin, turning it back into its oxygen-carrying form, and shortening the half-life of carbon monoxide in the body.
