Carbon monoxide poisoning. Be treated?

Yes, post acute carbon monoxide poisoning, 50% of the people may have delayed neurological symptoms like short term memory loss and confusion for upto 2 to 40 days. Chronic exposure however is more harmful. In case you are worried about serious neurological damage, please visit a neurologist and he/she may suggest a CT scan or MRI of the brain. Treatment for acute carbon monoxide poisoning is oxygen or hyperbaric oxygen. Depending on how much you had inhaled, whether there was unconsciousness or not the delayed symptoms may occur. As you are young, chances are that you should recover fully. If  this was due to a suicide attempt , please do visit a Psychiatrist in person to rule out Depression and undergo counseling. Hope this helps, All the Best!
