Why does gas poison people? What causes gas poisoning?

<> cold winter, homes that use coal stoves for heating are prone to gas poisoning if the smoke pipes are not tightly sealed or the windows are closed too tightly. Because coal cannot be burned 100% in the combustion process, it is easy to produce carbon monoxide toxic substances after coal burning, and in addition to incomplete combustion, a large number of toxic substances are produced, and poor indoor ventilation will cause gas poisoning to people sleeping in the house.

Usually, after a person is hit by gas, the initial symptoms will be headache and nausea, and in severe cases, it will cause vomiting and general weakness, and in severe cases, he will pass out and lose consciousness.

Gas poisoning occurs every year with many cases, gas can poison people, because when the air contains toxic gases, what is inhaled is carbon monoxide, carbon monoxide will soon combine with the blood when it reaches the blood, causing oxygen to not be able to combine with the blood, resulting in all parts of the body not being able to get oxygen. Therefore, people with severe poisoning will feel dizzy, their limbs will be weak, and they will be poisoned and die if they inhale gas for a long time or in large quantities.

If a gas poisoning patient is found, he should open the doors and windows as soon as possible, move the gas poisoning person to a place with fresh air outside, unbutton the neckline, call first aid**, and immediately do artificial respiration to help him breathe fresh air. Rescue breaths must be done until the patient is conscious or emergency personnel arrive.

Medically speaking, gas poisoning is more severe in men than in women, because men breathe more air than women. In addition, there is a possibility that the sequelae of poisoning may occur after the rescue of gas poisoning, that is, the brain reaction is sluggish than normal. The best way to prevent gas poisoning is to use other energy sources such as natural gas for heating to avoid gas poisoning.

Gas plays a very important role in people's family life, and in addition to the extremely common use of inflamed stoves, many families also have gas appliances such as gas water heaters and gas heaters. Compared with e-state fuels such as briquettes and firewood, gas is obviously very convenient. However, gas is a very toxic white gas, and people will unknowingly breathe into it, causing poisoning and even death.

What's going on? First of all, let's understand the breathing circulation of a person. Hemoglobin in the human blood is responsible for the transport of oxygen in the human body.

Hemoglobin binds to the inhaled oxygen in the lungs and carries it through the blood circulation to all parts of the body. But what you may not know is that carbon monoxide in gas can also bind to hemoglobin and is 200 times more powerful than oxygen. Therefore, once carbon monoxide is inhaled into the human body, the blood red egg will bind to it, and the delivery of oxygen can not be carried out, and after a long time, people will die due to low oxygen The experiment shows that when the carbon monoxide content in the air is exceeded, people will feel headache and nausea, and they will gradually coma after a long time, and if the rescue is not timely, there is a risk of losing their lives.

Gas poisoning incidents often occur in winter, because in winter, many families will close their windows tightly due to the cold weather, and in winter, people use a lot of gas appliances, so that gas is increased? The chance of leakage, the more likely it is to have gas poisoning accidents. In addition to piped gas, the use of briquette stoves at home is also prone to carbon monoxide poisoning accidents.

This is because when coal is not burned sufficiently, it produces toxic bodies, and these gases accumulate in the room to a certain concentration, which can also be the main culprit of poisoning incidents. <>

After living for so many years, I still know why gas poisons people!

Hello! If you leave the gas stove on all the time and don't burn anything, gas poisoning will definitely occur.

As long as the gas is turned on and not burned, gas poisoning will occur after the human body inhales to a certain concentration.

So, I advise you to be careful!

How can I prevent gas poisoning? Star Awareness Project

Gas poisoning: Coal gas is a type of gas, and the main component is methane, just like natural gas and other gases.

Carbon monoxide poisoning: Carbon monoxide is a type of emission gas produced by any combustible material in addition to carbon dioxide when it is not fully combusted.

The causes of poisoning are different and should not be confused.

Remind coal furnace users to pay attention to safety.

We often see on TV and on the news that there is a gas leak in such and such a community, resulting in people**. We need to use gas for cooking, but gas also has a certain danger, if the air contains an excessive amount of gas, it will poison people, light people are not breathing, nausea and vomiting. In severe cases, it can lead to heart and brain damage, and even death, so why does gas poison people?

Gas poisoning is caused by inhaling excessive amounts of carbon monoxide'It is a phenomenon of poisoning and hypoxia, so it is also called carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that is not easily detected by people and can easily enter the body with normal breathing, especially when people are sleeping. After entering the human body, carbon monoxide is distributed throughout the body with blood flow, which quickly causes a toxic reaction.

Carbon monoxide is very aggressive, and when the person inhales more than that, it will quickly enter the bloodstream, forcibly occupy all the red blood cells in the human body in a short period of time, and firmly grasp the hemoglobin in the red blood cells, so that it forms carboxyhemoglobin, which replaces the oxyhemoglobin formed by the combination of oxygen and hemoglobin under normal circumstances, so that the hemoglobin loses the function of transporting oxygen. Carbon monoxide binds to hemoglobin hundreds of times more than oxygen binds to hemoglobin. After carbon monoxide poisoning, the human blood cannot supply sufficient oxygen to the tissues and organs of the whole body in time, and the oxygen content in the blood decreases significantly, so that the body has extensive hypoxia symptoms, and even life-threatening.

Poisoned people will have a severe headache, followed by nausea, vomiting and shortness of breath, after which they will become confused, weak or convulsive, and will feel severely dizzy and finally unconscious and comatose when they exert themselves. The cause of death in general poisoning can be respiratory depression, arrhythmias, heart and brain damage. Decedent.

In daily life, carbon monoxide poisoning occurs from time to time, and most of them are caused by objective factors. The use of coal stoves for heating, barbecue, and cooking in closed rooms can cause a large amount of carbon monoxide to accumulate indoors due to poor ventilation and insufficient oxygen supply; Doors and windows are closed and there is no proper ventilation measure; The installation of the chimney of the bungalow is unreasonable, and the cylinder mouth is facing the vent, so that the gas flows backwards; The climatic conditions are not good, such as windy, snowy, cloudy, low air pressure, it is difficult for gas to circulate and discharge; Urban residents use piped gas, and the concentration of carbon monoxide in the pipeline is 25% to 30%, if the pipeline leaks, the switch is not tight, or the flame is extinguished during boiling, the gas overflows in large quantities; Use of gas water heater, poor ventilation, and long bathing time; Carbon monoxide poisoning can occur when you start your car in a garage or fall asleep in your car after starting the air conditioner in winter.

Therefore, it is necessary to pay attention to the prevention of gas poisoning at all times in daily life. For example, when using a coal stove reasonably, check whether the stove is in good condition and whether the flue is unblocked, especially before going to bed. Carbon monoxide gas alarms can also be installed in places where carbon monoxide gas may be generated, and when the concentration of carbon monoxide in the air exceeds the standard, audible and visual alarms can be used to remind people to take early evacuation measures.

Areas such as the chest** and lips are often cherry red.

Gas poisoning can easily cause a lot of damage to the body. Gas is what we call carbon monoxide. In case of carbon monoxide poisoning, there will definitely be a coma.

Some people die severely when they are poisoned by carbon monoxide, and even cause breathing difficulties. However, some people suffer from mild poisoning but do not know that their symptoms are actually caused by poisoning, which is a common occurrence.

1. How to prevent gas poisoning.

1) When using coal for heating or cooking indoors, be sure to pay attention to indoor ventilation and do not close doors and windows, because closing doors and windows will prevent the carbon monoxide produced in coal from flowing out to the outdoors, thereby increasing the indoor carbon monoxide concentration and finally causing gas poisoning. 2) You can install a carbon monoxide alarm at home, because a carbon monoxide alarm is an instrument that can detect the concentration of carbon monoxide. If the carbon monoxide concentration is too high, the instrument will automatically alarm and can make people detect gas leaks in time.

3) If you feel weak and dizzy when you sleep at night, you must pay attention and check the gas switch in time. If a gas leak is found, the valve must be closed and the doors and windows must be opened in time.

2. First aid methods for gas poisoning.

1) Let the patient leave the poisoned environment as soon as possible, move to an open and ventilated place, and immediately open doors and windows to circulate air.

2) Poisoned patients who are delirious must be lifted out of the poisoning environment as soon as possible, and their breathing, pulse, and blood pressure must be checked in the shortest possible time, and emergency treatment should be carried out according to these conditions.

3) Rest and breathe oxygen. Patients should rest quietly to minimize cardiopulmonary burden and oxygen consumption. If possible, the patient should be given artificial oxygen.

4) Cardiopulmonary resuscitation. If the patient's breathing, heartbeat is weak or even stops, CPR should be performed immediately until medical personnel arrive.

5) Strive for hyperbaric oxygen chamber as soon as possible to reduce sequelae. Even mild to moderate cases should be treated with hyperbaric oxygen chambers**.

The above is about the prevention and first aid of gas poisoning, which shows that carbon monoxide poisoning is very serious. Everyone must pay attention to it and take precautions. Don't stress after gas poisoning.

Promptly call Emergency**. Check the gas switch carefully every day before going to bed to avoid gas leakage due to the lack of relevant valves. Gas poisoning can only be prevented by taking precautions.

What harm can gas poisoning cause to the human body, if it is more serious, the damage is still quite large, whether it is physical or mental.

The hazards of gas poisoning are: due to excessive inhalation of carbon monoxide in the body, carbon monoxide and hemoglobin bind, and the binding of oxygen and hemoglobin is reduced, and then the tissue hypoxia is caused, at this time it can affect the lungs, heart, brain, kidneys and other important organs. If it causes a lack of oxygen to the brain, it may cause memory loss, and even dementia, coma, and death in severe cases.

Therefore, when poisoning, it is necessary to seek medical attention in time, and the hospital can take effective oxygen supply, ventilator to assist breathing, or hyperbaric oxygen therapy to improve these symptoms.

After the carbon monoxide in the gas enters the human body. Combines hemoglobin to form carboxyhemoglobin. It will lose the ability and function of carrying oxygen, destroy human cells, and cause suffocation and death.

Gas is a necessity in life, and gas poisoning can directly endanger life. So be sure to pay enough attention. Develop good, correct usage habits to avoid accidents.

<> gas poisoning is carbon monoxide poisoning, and once gas poisoning occurs in life, it is likely to directly endanger life. Even if detected and rescued early, some patients will experience permanent irreversible damage to their organs. So, how is gas poisoning caused?

How is gas poisoning caused?

The cause of gas poisoning is mainly due to excessive inhalation of carbon monoxide. Because carbon monoxide binds to hemoglobin 200 times more than oxygen. Once carbon monoxide is combined with hemoglobin to form carboxyhemoglobin, the amount reaches a certain level, which will cause hypoxia and ischemia poisoning in various organs and tissues of the human body, so gas poisoning occurs in a sealed environment.

What are the ways in which gas poisoning occurs?

1.The air in a closed room is not good.

If you use gas for cooking and heating in a closed room, but do not open the windows for ventilation, it will cause insufficient oxygen in the air and too much carbon monoxide. In addition, if the gas used is not installed correctly, it is likely to cause a large amount of gas leakage, and the gas is difficult to flow and discharge due to its low pressure.

2.There is a gas leak in the gas pipeline.

At present, many urban residents are using piped gas, if it is not turned off in time after use, when you go to bed at night, the gas pipeline will leak, which will make the gas overflow, and then cause gas poisoning.

Because there is carbon monoxide in the gas, carbon monoxide is very corrosive, and after entering the human body, it will quickly spread the blood of the whole body, and the hemoglobin in the blood cells will cause cerebral hypoxia, so the gas will poison people.

There is a large amount of CO in this gas, and carbon monoxide is colorless and odorless, very undetectable, and if absorbed by the body, it will combine with the cells of the body, resulting in a lack of oxygen, resulting in poisoning.

Because gas contains a large amount of carbon monoxide, the human body can be poisoned by inhaling carbon monoxide.
