If you think you are experiencing any of the symptoms (headache, dizziness, weakness, nausea, vomiting, chest pain or confusion) of CO poisoning get fresh air immediately. Open windows and doors for more ventilation, turn off any combustion appliances, and leave the house. Call your fire department (or 911) and report your symptoms. High levels of CO inhalation can cause loss of consciousness and death.
It is also important to contact a doctor immediately for a proper diagnosis. Tell your doctor that you suspect CO poisoning is causing your problems. Prompt medical attention is important if you are experiencing any symptoms of CO poisoning when you are operating fuel-burning appliances. Before turning your fuel-burning appliances back on, make sure a qualified service person checks them for malfunction.
