Final answer:
Immediate removal from the CO source, administration of oxygen, and possibly CPR are the initial treatments for carbon monoxide poisoning, with pregnant women requiring prolonged oxygen therapy.
Step-by-step explanation:
The initial treatment for carbon monoxide poisoning involves promptly removing the affected individual from the area of exposure to ensure that they are no longer inhaling CO.
If the person is unconscious, immediate CPR may be necessary. A key step in the treatment is administering oxygen through a non-rebreather mask, which can substantially reduce the half-life of carbon monoxide in the blood. This process facilitates the conversion of carboxyhemoglobin back to hemoglobin by increasing the dissociation of CO from the hemoglobin. In cases where pregnant women are affected, it's important to provide oxygen therapy for longer periods due to potential severe effects on the fetus.
