If you breathe in carbon monoxide, it enters your bloodstream and robs oxygen from blood cells. This is called carbon monoxide poisoning
Physical symptoms of carbon monoxide poisoning vary, depending on the amount in the bloodstream. The higher the concentration, the higher the danger.
- Low levels of carbon monoxide exposure can cause shortness of breath, mild nausea, fatigue, and mild headaches.
- Moderate levels can cause headaches, drowsiness, nausea, vomiting, confusion, dizziness, or light-headedness.
- Severe cases of carbon monoxide poisoning can result in unconsciousness and death.
Since many of the symptoms of carbon monoxide poisoning are similar to those of the flu, food poisoning or other illnesses, you may not think carbon monoxide poisoning could be the cause. If you or someone in your home has these symptoms, or if you have any doubts, get out of the house right away.
Call 911, your local fire department, or local emergency medical service from a nearby phone.
