Vanderbilt University Medical Center (VUMC) is reminding Tennesseans to be aware of the dangers of carbon monoxide poisoning during the holidays.

During the holiday season which brings colder temps, residents could be turning to a variety of different sources for heat which could also be a source of poisoning. Ashley Panas, the Chief Flight Physician for LifeFlight, says using heaters which use a fuel indoors is usually what causes issues.

Panas says those using propane or coal heaters indoors need to ensure proper ventilation and safety. Signs of carbon monoxide poisoning include dizziness and nausea. Other symptoms include feeling symptoms similar to the flu or COVID minus the fever. If one or more persons become ill with such symptoms at the same time, suspect carbon monoxide poisoning, get ventilation and call for assistance. If you or anyone you know suspects carbon monoxide poisoning, immediately seek fresh air and receive medical attention.
