Definition,Source and Causes of Carbon Monoxide Poisoning

What is Carbon Monoxide Poisoning :-

Carbon monoxide is a colourless, odourless and tasteless gas is produced on combustion of any fuel gas in the absense of adequate oxygen and ventilation and may lead to domestic carbon monoxiding Poising.

Source Of Carbon Monoxide Poisoning :-

The most common source of carbon monoxide poisoning is smoke inhalation. Other sources include heating systems in rooms that are not properly ventilated and exhaust fumes of petrol engine.

For example :- Wood, Kerosene heaters and Stoves and Brick Ovens.

Causes Of Carbon Monoxide Poisoning :-

Carbon monoxide poisoning is caused by inhaling combustion fumes. When too much carbon monoxide is in the air you are breathing, your body replaces the oxygen in your red blood cells with carbon monoxide. This prevents oxygen from reaching your tissues and organs.

Various fuel-burning products and engines produce carbon monoxide. Normally the amount of carbon monoxide produced by these sources isn’t cause for concern. But if they’re used in a closed or partially closed space — such as using a charcoal grill indoors — the carbon monoxide can build to dangerous levels.

Smoke inhalation during a fire also can cause carbon monoxide poisoning.

The Poisoning is most accidental exposure but can also be suicidal :

Mechanism Of Toxicity :-

Carbon Monoxide readily combines with haemoglobin to form carboxyhaemoglobin prevents the formation of oxyhaemoglobin thus, leads to decrease in oxygen carrying capacity of blodd. It also shifts the oxygen dissociation curve to the left, further reducing the oxygen available to the tissues.

Carbon monoxide acts as a cellular poison competes with oxygen for other haematoproteins such as myoglobin and enzymes. In the initial stage, it is transported to the tissues via plasma and not via haemoglobin. Therefore, blood carboxyhaemoglobin levels may be normal in early stages of poisoning. Here are some other causes of carbon monoxide gas emission and buildup:

• Smoking cigarettes causes blood levels of carbon monoxide to rise.

 Leaving a car in a closed garage with its engine running can produce deadly amounts of carbon monoxide within 10 minutes. carbon monoxide poisoning

• Burning charcoal produces carbon monoxide gas.

 Blocked flues and chimneys can stop carbon monoxide from escaping.

• Fumes from certain paint removers and cleaning fluids can cause carbon monoxide poisoning.
