The treatment for CO poisoning is high-dose oxygen, usually using a facemask attached to an oxygen reserve bag. CO levels in the blood may be periodically checked until they are low enough to safely send you home.

  1. In severe poisoning, a pressure chamber may be used, if available, to give even higher doses of oxygen.
  2. It is important to find the source of the CO. Your local fire department or public service company will help find the source of CO and make sure the building is safe.
