Early Signs of CO Poisoning
CO poisoning, caused by exposure to carbon monoxide gas, can be chronically debilitating at low levels and quickly fatal at higher levels. Carbon monoxide, a byproduct of combustion in gas-fired furnaces, stoves, motor vehicles and even wood-burning fireplaces, is odorless and colorless and may accumulate inside a home without occupants being aware of it. This is why it is so important to know the early signs of CO Poisoning. At up to 70 parts per million (ppm) of CO concentration in indoor air, most people will experience no symptoms. Between 70 ppm and 150 ppm, symptoms may be vague and easily dismissed as indications of any number of other illnesses. Above 150 ppm, disorientation, unconsciousness and death from CO poisoning can occur in rapid succession.
Know the Early Signs of CO PoisoningBecause the effects of CO poisoning vary according to the concentration in the air and individual factors like age and general health, it’s important to be aware of early symptoms like these:
- Shortness of breath or labored breathing.
- Nausea and loss of appetite.
Specific Signs of CO PoisoningSince these symptoms mimic early stages of other common illnesses, especially the flu, also be aware of these additional factors that are specific to CO poisoning:
- Symptoms disappear or greatly diminish when you leave the house for any length of time.
- Everyone living in the house reports symptoms instead of only one or a few individuals, as with common flu.
- Those who spend the most time at home have the most severe symptoms.
- The symptoms are not accompanied by other classic flu-like signs such as fever or swollen glands.
- Household pets may also become lethargic, lose appetite and show other unexplained symptoms.
