What are the characteristics of gas poisoning and what are the symptoms of gas poisoning

Mild dizziness, vomiting, severe difficulty breathing, reduced willpower, fainting.

Gas poisoning is carbon monoxide poisoning, the clinical manifestations are mainly hypoxia, mild cases have headache, weakness, dizziness, dyspnea during labor, cherry red lips, nausea, vomiting, confusion, collapse or coma and other symptoms; In severe cases, it is a deep coma, accompanied by high fever, increased muscle tone in the limbs, paroxysmal or tonic spasms, cerebral edema, pulmonary edema, myocardial damage, arrhythmias, and respiratory depression, which can cause death.

I have panic, headache, and panic for a while, and I don't know if it's gas poisoning.

There is no such thing as chronic poisoning with carbon monoxide.

Manifestations of gas poisoning:

1. Mild: The poisoning time is short, manifested as the early symptoms of poisoning, headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, and even short-term fainting.

2. Medium-sized: the poisoning time is slightly longer, and on the basis of mild symptoms, prostration or coma may occur. ** and mucous membranes with a cherry red color characteristic of gas poisoning.

3. Severe: If the time is found too late, too much gas is inhaled, or a high concentration of carbon monoxide is inhaled in a short period of time, the patient presents a deep coma, various reflexes disappear, incontinence, cold limbs, blood pressure drops, shortness of breath, and will die quickly. In general, the longer the coma, the more serious the prognosis, often with sequelae such as dementia, memory and comprehension loss, and limb paralysis.

Gas poisoning: Gas poisoning in the household mainly refers to carbon monoxide poisoning, liquefied petroleum gas, pipeline gas, and natural gas poisoning.

Carbon monoxide poisoning is inhalation through the respiratory tract when the products of incomplete combustion of carbon-containing substances occur. It is more common in winter when coal stoves are used for heating, doors and windows are closed, and smoke exhaust is poor.

Liquefied petroleum gas, pipeline gas, natural gas poisoning, common in liquefied stove leakage or gas pipeline leakage, etc.

Gas poisoning according to the concentration of carbon monoxide contained in the inhaled air, the length of poisoning time, when the volume of carbon monoxide in the living room reaches, people will feel dizzy, headache, nausea, vomiting, weakness of limbs and other symptoms, more than that, as long as inhaled for half an hour, people will be asleep, and then coma, when reached, as long as inhaled for 1 hour can cause death.

Symptoms of mild gas poisoning, such as dizziness, brain bloating, nausea and vomiting.

Symptoms of severe gas poisoning, such as weakness of limbs, coma, and foaming at the mouth.

What are the symptoms of gas poisoning? How to prevent it?

1) ** and symptoms: Gas poisoning is also known as carbon monoxide poisoning. It is common in winter or early spring when the chicken coop burns coal for heating, due to the chimney blockage, excessive coal filling and poor burning, coupled with poor ventilation, resulting in high indoor carbon monoxide concentration and poisoning.

The victim chick shows lethargy, strained breathing, ataxia, and preceded by convulsions and convulsions. In subacute poisoning, the feathers are fluffy, appetite is reduced, and growth is slow. On autopsy, acute cases may reveal bright red blood, ** mucous membranes and muscles cherry red.

2) Prevention and control measures:

As soon as poisoning is detected, immediately move all chickens to a place with fresh air or quickly open the doors and windows of the chicken coop.

Pay attention to the stove in good condition, clean the chimney frequently, and pay attention to the ventilation of the chicken coop.

Winter is coming, every household has its own heating method, the general family is to choose briquette stove heating, but remind, while heating, pay attention to keep indoor ventilation Oh, when the air carbon monoxide to a certain extent will cause the danger of gas poisoning, today I will tell you about the winter heating to pay attention to the problem, so what are the causes of gas poisoning? How can I prevent gas poisoning?

1. Causes of gas poisoning

1. Coal stove is used in winter, and ventilation facilities are not installed indoors.

2. The coal furnace is not tightly sealed and leaks.

3. The coal furnace has been used for a long time, and the chimney is blocked by ash.

4. The part that extends to the outside of the house is not equipped with a windproof cap, which produces backwind.

5. Use the stove to cook during the day and heat at night.

2. Methods to prevent gas poisoning

1. After cooking, you must check whether the stove and pipe valves are closed.

2. Regularly check whether the hose is firm, and replace the aging hose in time, preferably once a year.

3. Don't sleep in a room with gas facilities, such as changing the kitchen into a bedroom during renovation.

4. The boiling water should be taken care of, and the water should not be too full, so as not to overflow and extinguish the fire.

5. When using the electric cooker to cover the beam, check whether it is on fire after hearing the sound of ignition.

6. If you need to change the use of the gas facilities without permission, you must apply to the Gas Management Office, and a special person will be responsible for the installation, and the modified facilities will be scientifically stressed.

7. When renting the house to outsiders, the renter should be instructed to standardize the operation.

8. When using a gas water heater, pay attention to exhaust air, keep the air unblocked, and do not install the gas water heater in the bathroom.

9. The stove should be matched with the gas source, such as using gas, and the stove such as natural gas cannot be installed.

10. Install a gas alarm and plug in the power supply to keep it in working condition at all times.

3. Why does carbon monoxide poison

This is because carbon monoxide binds to hemoglobin 200 times more than oxygen binds to hemoglobin, and once combined, it is difficult to separate them. Gas poisoning can kill people in silence.

After gas poisoning, people with mild poisoning may experience dizziness, headache, nausea, vomiting, and confusion. For those who are severely poisoned, the lips will be cherry red, the whole body will be flushed, delirious, and even comatose, short of breath, cold limbs, and even incontinence.

Methane, carbon monoxide, and hydrogen sulfide are chemical asphyxiating gases for nerve cells, which can quickly penetrate the cell membrane and cause nerve cell poisoning, resulting in cerebral edema and brain herniation.

Carbon monoxide is colorless and odorless, and often in unexpected situations, especially during sleep, it unknowingly invades the respiratory tract, enters the bloodstream through the exchange of gas in the alveoli and spreads throughout the body. Carbon monoxide is very aggressive, and the concentration of carbon monoxide in the air can quickly enter the bloodstream, forcibly occupy all the red blood cells in the human body in a relatively short period of time, and hold on to the hemoglobin in the red blood cells, so that the hemoglobin loses the function of transporting oxygen. Since the oxygen in the human body is only enough to consume for 10 minutes, it quickly causes coma and is life-threatening.

Symptoms of gas poisoning

Mild gas poisoning is mainly manifested as headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, confusion, may be comatose but the duration is short, and the person who is out of the scene can wake up quickly, and there are generally no obvious complications.

In patients with severe poisoning, the degree of impaired consciousness can reach deep coma, and trismus, tonic generalized spasms, and incontinence often occur. Some patients may be complicated by cerebral edema, pulmonary edema, severe myocardial damage, shock, respiratory failure, upper gastrointestinal bleeding, panel blisters or patches of panel redness and swelling, muscle swelling and necrosis, and liver and kidney damage.

Causes of gas poisoning: In rural areas, gas poisoning is often caused by carbon monoxide produced by insufficient combustion of briquettes or lumps of coal. Rural families often use coal stoves for heating in winter, if the house is strongly closed, and the gaps between doors and windows are low, the gas is not easy to discharge and fills the whole room, which is very easy to cause gas poisoning.

In addition, use the stove for cooking during the day and the stove for heating at night; The long-used coal stove chimney is clogged with ash; The part of the chimney that extends to the outside of the house is not equipped with a windproof cap, which produces backwind; In windy, snowy, cloudy weather, low air pressure and other weather, it is difficult to circulate and discharge gas, which are the main causes of gas poisoning in rural residents.

In cities, the carbon monoxide content in the piped gas used by residents is 25% to 30%, which can cause poisoning if the pipeline leaks, the switch is not tight, or the gas overflows after the flame is extinguished during cooking.

In addition, due to the small space in the bathroom and poor air flow, if you take a bath in the bathroom with a gas water heater for a long time, it is also very easy to cause carbon monoxide poisoning. In addition, when the car is in a confined space, the occupants of the car fall asleep in the car without turning off the engine, which is also one of the main causes of carbon monoxide poisoning.
