What I Learned From Sitting in a Bar? – Carbon Monoxide Poisoning
14 Sep 2008
Where do I get ideas for this column? It’s usually from long hours of reading medical reports, talking to researchers, searching the net and various sources. It can be tedious and tiring. But this week I got lucky. I was having a drink at my favourite watering hole when a friend said to me, "You should write about a problem I know that kills people. It also makes them ill and they don’t realize the cause of their poor health". He then told me some tragic stories.
He said, "A child vomited and appeared to be having a seizure. No one knew why. In another case two women, swimming in a cluster of boats, suddenly lost consciousness and nearly drowned. Two others were found dead in a cabin cruiser for no apparent reason". He went on about another person who complained of headaches only in the winter. So what was the final diagnosis? Carbon monoxide (CO) poisoning. It was the culprit in all these cases.
We’ve all heard stories of depressed persons who commit suicide by sitting in a running car in an closed garage. But few people realize that gas from a cluster of boats can also generate enough CO to affect swimmers. Exhaust fumes can also flow back into the boat. And if you suffer from headaches, fatigue and general malaise only in the winter it may be due your wood burning stove, a defect in the heating system or a blocked chimney that’s filling the air with CO.
This year 500 people will die from CO poisoning in North America and another 40,000 will require hospital treatment. That’s because victims are unaware that CO is present as it has no odour, colour or taste. The only protection is a carbon monoxide detector. And studies show that although most people have smoke alarms, 50 percent of households do not have a CO detector.
My bar friend made my research easier this week. His task is to inspect homes to determine if CO presents a hazard. And he told me that some people live on the edge without knowing CO is present and causing their health problems.
CO gas is measured in parts per million (ppm) and 9 ppm is considered to be a health hazard. Since cigarettes emit carbon monoxide, his home inspections often show 8 to 10 ppm. Small wonder that smokers often complain of headaches and feel tired all the time.
One of my friend’s remarks reminded me of the "Bingo Brain Syndrome". A woman was admitted to hospital complaining of chest pain and mental confusion. She smoked two packs of cigarettes daily and was an ardent bingo player three nights a week. Further research revealed that of the 310 bingo players involved 304 smoked. The woman’s diagnosis was CO poisoning.
Today we worry about deaths due to drunk drivers. But we may never know the number of fatalities that occur because chain smokers fall asleep from increased amounts of CO inside the car.
Few people consider the lighting of candles hazardous apart from the danger of fire. But if power fails and several are lit in a small room, Co gas is produced. So think twice if you’re planning to add romance to your life by opening a bottle of wine and lighting candles. Your partner may get a little drowsy at the wrong time.
This winter don’t be a victim of CO poisoning. Remember that when fuels such as wood burning stoves, natural gas, oil or kerosene have insufficient oxygen for full combustion, CO is formed and can set the stage for tragedy. CO binds to hemoglobin in the blood 250 times greater than oxygen and in concentrations of 12,800 ppm you’re unconscious after three breaths! And death occurs within three minutes.
If you have smoke detectors in your home add CO detectors as well. Or purchase one such as the Kidde type that alerts you to both CO and smoke. Moreover, never assume that when the bell rings it’s a false alarm. Get everyone out of the house as quickly as possible as a few moments of exposure to CO can mean the difference between life and death.
Hmm. This has been a good week. I’ll visit my favourite watering-hole more often!
