What are the symptoms of carbon monoxide (CO) exposure?
Symptoms of mild exposure to CO consist of nausea, vomiting, headaches, dizziness, blurred vision, and fatigue. Symptoms of a medium or high exposure can include confusion, drowsiness, fainting, convulsions, and difficulty breathing. Everyone is at risk for CO poisoning; however, expectant mothers and the unborn child, infants, children, senior citizens, and people with heart or lung problems are more vulnerable to the effects of CO.

Consider CO as a possibility if more than one member of your household experiences the same symptoms or the symptoms go away when you leave the home and return when you re-enter the home.
