Treatments and drugs
By Mayo Clinic staffThe goal of treatment is to replace the carbon monoxide in your blood with oxygen. In the hospital, you may breathe pure oxygen through a mask placed over your nose and mouth. This helps oxygen reach your organs and tissues. If you can't breathe on your own, a machine (ventilator) may do the breathing for you.
In some cases, hyperbaric oxygen therapy is recommended. With this therapy, you're placed in a full-body pressurized chamber. Inside the chamber, air pressure is more than twice as high as normal atmospheric pressure. This speeds the removal of carbon monoxide from your blood.
