Carbon Monoxide Poisoning: The Silent, Odorless Killer

What is Carbon Monoxide?

Carbon Monoxide, also known as CO, is an odorless, colorless gas that is given off when products containing carbon are incompletely burned. The gas is produced by many things we use every day: cars, trucks, small gasoline engines (lawn mowers, snow blowers), stoves, lanterns, gas furnaces and generators and water heaters. Such machines and appliances should be operated only in well-ventilated places so the carbon monoxide doesn't accumulate.

Carbon monoxide kills 500 people every year in the United States. This gas can affect otherwise healthy individuals, but can more seriously harm infants, people of all ages with lung or heart disease, or anemia.

According to www.emedicinehealth.com, carbon monoxide is the leading cause of accidental poisoning deaths in the United States.

How does CO Poisoning Happen?

If cars, trucks or other machines or appliances are run in a confined space the carbon monoxide builds up. CO molecules are smaller than oxygen molecules and are absorbed by the blood faster than oxygen. If there is sufficient CO in the air, the lungs will take in more carbon monoxide than oxygen. When carbon dioxide is breathed out, it is replaced by carbon monoxide instead of oxygen. In more scientific terms, it actually impairs the body's ability to carry oxygen to organs and tissues.

Carbon monoxide impairs a person's visual perception, and ability to exercise, pick things up with their hands, learn new information or perform more challenging tasks.

According to the U.S. Environmental Protection Agency, incomplete combustion of fuels is more likely to occur where there is low air-to-fuel ratios in the engine itself. These conditions are usually more common in the winter when catalytic converters and other engine parts responsible for combustion operate less efficiently, or if cars or other appliances are not properly maintained or installed correctly.

Symptoms of Carbon Monoxide Poisoning

The CDC reports that the most common symptoms of carbon monoxide poisoning include:

- headache
- dizziness
- fatigue
- nausea
- vomiting
- chest pain

Can CO linger in ones lungs after it is discovered in ones home. I wonder if my shortness of breath is related to that although it has been over a month.

In cases of acute poisoning, there may be permanent damage to the brain or heart because of the lack of oxygen, and recovery can be slow.

According to the CDC, the carbon monoxide that we might breathe in over the course of an ordinary day takes 24 hours to completely leave our lungs. It stands to reason that larger amounts of carbon monoxide could take longer to leave your lungs, but that is really something you need to discuss with your family doctor. They can do a blood test to see if there is still carbon monoxide in your system, assuming that the original source for the carbon monoxide levels in your home has been addressed.

The shortness of breath you're experiencing could be a lingering effect of your exposure to carbon monoxide, but it could also be associated with something else. You need to discuss it with your family doctor. Perhaps other readers who have experienced CO2 poisoning can offer their "follow-up" stories.
