- What Are the Signs and Symptoms of Carbon Monoxide Poisoning?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Back during the energy crisis, I had our house weatherproofed and
- insulated. However, after hearing about carbon monoxide poisoning occurring
- in airtight houses, I now make sure to leave a few windows slightly open. All
- this concern has left me wondering about the signs and symptoms of carbon
- monoxide poisoning. What can you tell me?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Carbon monoxide, or CO, is a colorless, odorless gas created by the
- incomplete combustion of carbon-containing materials. A major component of
- automobile exhaust and a significant part of cigarette smoke, CO is
- responsible for half the annual U.S. poison fatalities.
- Inhaled and absorbed into the blood stream through the lungs, CO binds
- with hemoglobin in the red blood cells, preventing the cells from absorbing
- the oxygen they normally carry to all parts of the body. Because of their
- need for oxygen, the brain and the myocardium--the thick muscles of the
- heart--are particularly at risk from CO poisoning. Symptoms may range from a
- simple headache or lightheadedness, to nausea, visual disturbances or heart
- palpitations. CO poisoning can cause comas, abnormally low blood pressure,
- irregular heartbeat or convulsions, and lead to death from respiratory
- failure. Delayed signs of CO poisoning include emotional disturbances,
- disorientation, loss of control over speech and movement, incontinence and
- muscular rigidity.
- Overexposure to CO is best remedied by treatment with 100% oxygen, and,
- if necessary, the administration of hyperbaric oxygen--100% oxygen
- administered at 2.8 times normal air pressure. Preventive measures are the
- best to take when dealing with CO, since its effects are so deadly, and the
- unborn child is particularly at risk: make sure your house or workplace is
- well ventilated, even in cold weather; check that furnaces, heating appliances
- and autos are operating properly, and to quickly eliminate one easily
- avoidable source of CO, stop smoking!
