It depends : It depends on the co level in the blood, and type of treatment available.

Depends on severity: Mild or moderate symptoms can last from less than an hour to many hours, depending on the severity of the carbon monoxide (CO) poisoning, the type of treatment, the victim's other health issues, etc... Studies show the half-life of carboxyhemoglobin (CO bound to hemoglobin) to be about 4 hours (3-5 hr) when breathing regular air, and about 1 hour (30-90 minutes) when breathing 100% oxygen.

Depends: The duration of symptoms depends on the concentration of carbon monoxide in the blood stream, the duration of exposure and how quickly you are removed from the carbon monoxide environment.
