Poisoning from inhalation of carbon monoxide.

Expectations (prognosis)

If the individual recovers, it will be slowly. Depending on the exposure levels of carbon monoxide and the time of exposure, permanent brain damage may occur. If the individual still has symptoms of impaired mental ability after two weeks, the likelihood of complete recovery is not very good. Even if an individual is symptom free for a while, impaired mental ability can reappear within the first 1-2 weeks.
