Limit the risk of incomplete combustion by maintaining your devicesįortunately, not all combustion produces carbon monoxide (nor the danger of carbon monoxide poisoning).Ĭarbon monoxide being released is the result of incomplete combustion, which can result from poor management or inappropriate use of combustion appliances or fuels, or a lack of maintenance of the relevant exhaust ducts. Generators, stoves, boilers, water heaters or cars can also cause carbon monoxide emissions. ![]() Heaters are, therefore, most often involved in emitting carbon monoxide, although they are not the only appliances that can be the source. This toxic gas can be produced from the combustion of wood (logs, pellets, etc.), gas (butane, propane, natural gas, etc.), coal, petroleum, gasoline or fuel oil. In order to avoid experiencing the symptoms of carbon monoxide poisoning, it is essential to understand CO emanation, what it is and how to prevent it. How do I avoid carbon monoxide poisoning? The main causes of accidents and poisonings linked to carbon monoxide are poor evacuation of combustion products, lack of ventilation in the room where the appliance is placed, and poor maintenance of heating appliances. This makes it one of the most dangerous gases in our modern lifestyles. ![]() It’s estimated that in an enclosed space, without any action being taken, carbon monoxide poisoning can kill a person within an hour. These symptoms present differently in different people and situations, so you shouldn’t look for the symptoms to appear in a certain order, or assume that they’re nothing serious. The longer the exposure to the gas, the more serious the adverse health effects, so don’t waste time. These issues are far from trivial, especially during winter in a closed and heated room.Įvery minute counts with carbon monoxide poisoningĪs soon as any of these symptoms of carbon monoxide poisoning appear, especially if the heating is on, you should be highly concerned, and suspect that carbon monoxide is the cause. However, the initial symptoms of carbon monoxide poisoning appear rapidly: This is due to the fact that CO has no smell or taste, and does not irritate the eyes or throat. This process is rapid, but before the first symptoms become visible, it’s impossible to know that it’s taking place. So, what happens in the event of exposure to this poisonous gas? The moment it is inhaled by a person, carbon monoxide begins to replace oxygen in the blood. ![]() Multiple symptoms that should raise the alarm Also, it doesn’t rise like smoke, but instead mixes with the ambient air in a room. It also diffuses quickly in the surrounding environment. Carbon monoxide is not only harmful to the body (in both humans and other mammals). These can often occur during the winter, when our home heaters are running at full speed and ventilation levels are lower, as we tend to keep our windows shut.Ĭarbon monoxide emissions are the main cause of poisoning in industrialised countries, so it’s vital that we know the relevant symptoms. Given the neurocognitive sequelae following CO poisoning, increased awareness and prevention of CO poisoning is imperative.Various symptoms, the severity of which depends on the duration of exposureĬarbon monoxide gas causes multiple deadly poisonings each year: in England and Wales, there are around 60 fatalities annually, according to the NHS. Unfortunately, there appears to be no marker or constellation of signs or symptoms at presentation that predicts long-term outcome following CO poisoning. CO poisoning, even when treated with supplemental oxygen can leave the patient with permanent neurocognitive or affective problems. Hyperbaric oxygen therapy (HBO2) is accepted in CO poisoning, although data from randomized clinical trials regarding the efficacy of HBO2 in CO poisoning is conflicting. Emergency treatment for CO poisoning is 100% oxygen. ![]() Additionally, various animal studies have demonstrated that CO interferes with myoglobin, P450, and other enzyme function causes lipid peroxidation through neutrophil activation produces oxidative stress manifested by peroxynitrate deposition in endothelium binds to cytochrome aa3, disrupting intracellular oxygen utilization can cause neuroexcitotoxicity and contributes to hippocampal cellular death through apoptosis. Carbon monoxide (CO) poisoning is common and frequently unrecognized since the signs and symptoms are relatively nonspecific.
