What are the three manifestations that indicate gas poisoning, and how should they be diagnosed and

Gas is a thing that many people use in their homes, mainly for combustion. As early as the seventies and eighties of the twentieth century, China said goodbye to briquettes and used gas. Over the years, gas has brought a lot of convenience, but there are certain hidden dangers in daily life, and in recent years, there have been news reports that some families have been poisoned due to gas leaks.

The main ingredient in coal gas is carbon monoxide, which is a colorless and odorless gas with a lower density than air. Carbon monoxide binds to hemoglobin in the blood, but it separates very slowly, making it difficult for hemoglobin to rebind to oxygen, so that the body does not have enough oxygen, and gas poisoning will occur. Let's take a look at the symptoms of gas poisoning.

1. Dizziness, palpitations, and weakness of limbs

It is a symptom of mild gas poisoning. The time is short, carbon monoxide is not completely bound to hemoglobin, and there is a certain amount of oxygen transported in the blood, which will manifest as headache, dizziness, weakness of limbs, vomiting and other symptoms. But at this time, if the person is still a little sober, immediately go to a place with fresh air, get out of the toxic environment, inhale oxygen to combine oxygen with hemoglobin, at this time the symptoms will disappear quickly, and there will be no sequelae.

2. Pale and confused

Medium-sized poisoning, carbon monoxide and hemoglobin have been combined by about 30% 40%, and the blood is difficult to supply oxygen, showing symptoms of paleness, confusion and even coma. **It also exhibits the pink or cherry red color characteristic of gas poisoning. At this time, it is moderately poisoned, and if it is rescued in time, it can be recovered within a few days.

3. Deep coma, incontinence, and decreased blood pressure

At this time, these symptoms are usually caused by inhaling too many high concentrations of carbon monoxide for a short period of time or breathing for too long during sleep at night. In general, the longer the coma, the higher the mortality rate. At this time, it has a certain impact on the brain, and there will be some sequelae after rescue, such as dementia, paralysis, etc.

If gas poisoning is mild and medium-sized, if the rescue is timely, there are generally no sequelae after recovery. But if it is severe poisoning, then it is life-threatening. Therefore, we must be vigilant about gas leaks in our lives and deal with them in time.

Let's take a look at what you can do after being poisoned.

1. Open the window in time

If you are still conscious after gas poisoning, open the doors and windows immediately to reduce the concentration of carbon monoxide in the air, go to a well-ventilated place, and breathe fresh air. If you find someone poisoned by gas, you should also open the doors and windows immediately, be careful of your own poisoning, and then move the poisoned person to a place with fresh air and pay attention to keeping warm.

2. Keep your airway smooth

After moving the patient to a place with fresh air, care should be taken to keep the patient's airway clear so that their airways are adequately oxygenated. If the patient is found to be in respiratory arrest, the emergency responder** should be called immediately, and mouth-to-mouth rescue breaths should be performed, chest compressions should be performed, and the mouth and nose should be cleaned up in time to avoid blocking the airway.

If there are symptoms, it is recommended to immediately turn off the gas valve, and open the windows and doors for ventilation to prevent poisoning from being too deep, resulting in coma.

1. Dizziness, palpitations, and weakness of limbs are symptoms of mild gas poisoning

2. Pallor, confusion, medium-sized poisoning, carbon monoxide and hemoglobin have been combined by about 30% 40%, and the blood is difficult to supply oxygen, which is manifested as paleness, confusion and even coma.

3. Deep coma, incontinence, and blood pressure drop, at this time it is already severe, and these symptoms will generally occur when inhaling too much high concentration of carbon monoxide in a short period of time or breathing for too long during sleep at night.

Gas poisoning refers to the poisoning phenomenon caused by the leakage of gas and then inhaled by our human body when we use it.

When using gas, we must pay a lot of attention. First of all, we must understand that the most important component of gas is carbon monoxide, carbon monoxide is flammable, after contact with oxygen, it will burn when it reaches a certain level of high temperature, which is the best of our gas stove. In the process of use, we must pay great attention to the fact that if carbon monoxide is in contact with a large amount of air, and then it is likely to cause the occurrence of ** after contact with open flame, then such a tragic situation is something that many people do not want to see.

Therefore, when we use gas, we must get a lot of attention to avoid these tragedies.

Every day, after using the gas stove for stir-frying, the main valve switch of the gas stove must be closed, and after it is closed, it is also necessary to prevent infants and young children from opening the main valve when playing, so at this time, the main valve must be installed in a hidden place, and it is a place where the baby has no way to reach. Usually check whether the gas stove is turned off or whether the gas tank is in a leaking state every time you use it. If the main valve of the gas stove is closed, but the gas tank is often in a state of leakage, then one day the gas leakage will reach a certain level, and when the child is alone at home, it is easy to cause gas poisoning.

At this time we should know,Once we find a gas leak, all we have to do is open the window for ventilation and don't turn on the switch. The purpose of opening windows for ventilation is to allow air to circulate to our homes and to dissipate the carbon monoxide contained in our homes, reducing the concentration of carbon monoxide in our homes. Don't turn on the switch, because the indoor carbon monoxide concentration, once the switch reaches a certain level, there will be an electric spark, as long as the electric spark and oxygen and carbon monoxide exist at the same time, it is easy to cause**,**After the occurrence, it will definitely lead to personnel**.

Therefore, when using gas, we must make sure that we and our families clearly understand how to use gas and what to do if we find a gas leak

What we usually call gas poisoning actually refers to carbon monoxide poisoning, that is, a large amount of carbon monoxide binds to hemoglobin, so that oxygen loses the opportunity to bind to hemoglobin and cannot be transported by the blood to tissue cells, resulting in tissue hypoxia. Common preventive measures mainly include opening windows for ventilation, ensuring smooth chimney ventilation, and installing alarms at coal fires.

Gas poisoning actually refers to carbon monoxide poisoning, and if you want to prevent it, you should ventilate it more often and don't keep the windows closed all the time.

It refers to carbon monoxide poisoning, which can be prevented by reducing the use of gas in daily life and turning off the valve after use.

Most patients quickly develop spasms, coma, cherry red cheeks, chest** and lips, if the treatment is not timely, respiratory depression and death can be quickly achieved. According to the concentration of carbon monoxide contained in the inhaled air and the length of time of poisoning, gas poisoning is often divided into three types:

1) Mild: the poisoning time is short, and the carboxyhemoglobin in the blood is 10 20. It is manifested as the early symptoms of poisoning, headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, and even short-term fainting.

2) Medium: the poisoning time is slightly longer, the carboxyhemoglobin in the blood accounts for 30 40, and on the basis of mild symptoms, collapse or coma can occur. ** and mucous membranes with a cherry red color characteristic of gas poisoning.

If the rescue is timely, it can wake up quickly, recover completely within a few days, and generally have no sequelae.

3) Severe: found too late, inhaled too much gas, or inhaled high concentrations of carbon monoxide in a short period of time, blood carboxyhemoglobin concentration is often above 50, the patient presents a deep coma, various reflexes disappear, incontinence, cold limbs, blood pressure drops, shortness of breath, and will die soon. In general, the longer the coma, the more serious the prognosis, often with sequelae such as dementia, memory and comprehension loss, and limb paralysis.

If gas poisoning occurs in the family.

Dizziness, nausea, unsteadiness on standing.

In the cold season, using coal as fuel to maintain the temperature of the rabbit house, if the management is not good, it is easy to cause gas leakage in the coal furnace, which can cause poisoning.

Symptoms: mild poisoning, sick rabbits show shy tears, vomiting, cough, tachycardia, dyspnea. At this time, if you can get out of the poisoned environment in time, you can recover quickly with or without it.

Severe poisoning, when the carboxyhemoglobin in the body reaches 50%, the rabbit quickly becomes unconscious, perceptual impairment, reflex loss, unsteady walking, paralysis of the hindquarters, and cold limbs. The visible mucous membranes are cherry red, pale, or cyanosis, sometimes sweating profusely, the body temperature rises first and then falls, the pulse is weak, and the pupils are dilated. If not timely**, eventually die of cardiac paralysis.

Autopsy showed small bright red hemorrhagic spots in the blood vessels and various organs, and the blood was bright red.

It is worth noting that newborn rabbits are very sensitive to gas. If there is a small amount of gas (i.e. carbon monoxide) in the room, it can cause death. And at this time, there is no reaction from adult rabbits and humans.

Diagnosis: a preliminary diagnosis can be made based on exposure history and clinical symptoms. If available, laboratory tests can confirm the diagnosis if the amount of carboxyhemoglobin in the blood is significantly increased.

Prevention: Before the rabbit farm enters the winter, the heating and other equipment should be overhauled, and the breeding personnel should be vigilant to ensure that the rabbit house is well ventilated.

**: Immediately transfer the poisoned rabbit to a place with fresh air, take artificial respiration on the rabbit, and immediately deliver oxygen if possible.

Intravenous injection with 10% glucose injection plus vitamin C, chloral hydrate, chlorpromazine and other drugs can also be used to relieve spasm in sick rabbits, and subcutaneous injection of cardiotonic agents.

If you have difficulty breathing and failing, you can give oxygen mixed with a certain concentration of carbon dioxide to stimulate the respiratory center, and inject Meilan solution intravenously, which has a good effect. Attention should be paid to heat preservation during the rescue period.

Gas poisoning is actually carbon monoxide poisoning.

It is because of the lack of oxygen to the brain and the serious damage to the nervous system caused by the inhalation of high concentration of carbon monoxide gas, it is very harmful to the human body, and people are delirious, stupid, dizzy, nausea, vomiting, etc. due to carbon monoxide poisoning, and the severe ones are unconscious, some up to a few days, and the nervous system is seriously damaged, and even death.

If the room is not well ventilated, after the person inhales this gas, it quickly combines with the hemoglobin in the blood, affecting the inhalation of oxygen.

Pay attention to ventilation to prevent flue blockage and air leakage, use heating water during the day, it is best to move outside at night, in case someone has gas poisoning, you should rescue it as soon as possible. Doors and windows should be opened, ventilation should be given, and the patient should be lifted to a fresh place where the patient should lie down.

Coal gas is an unstable mixed gas produced when coal and other carbon-containing substances are burned, mainly containing carbon monoxide, hydrogen, methane, ethylene, butene, nitrogen, carbonic acid, hydrogen sulfide, etc. Oxygen and carbon monoxide can be combined with hemoglobin, and the binding capacity of carbon monoxide and hemoglobin is much larger, so that more hemoglobin and carbon monoxide bind, and because carbon monoxide and hemoglobin are separated very slowly after binding, and the number of hemoglobin is limited, so that oxygen loses the opportunity to combine with hemoglobin, and can not be transported to tissue cells by blood, resulting in hypoxia of tissue cells

Therefore, the answer is: gas poisoning actually refers to carbon monoxide poisoning; When people are in a place with a high concentration of carbon monoxide, poisoning will occur, carbon monoxide and oxygen can enter the lungs through the ventilation of the lungs at the same time, and then enter the blood through the gas exchange in the alveoli, oxygen and carbon monoxide can be combined with hemoglobin, and the binding capacity of carbon monoxide and hemoglobin is much larger, so that more hemoglobin and carbon monoxide are combined, and because carbon monoxide and hemoglobin are separated very slowly after combining, and the number of hemoglobin is limited, so that oxygen loses the opportunity to combine with hemoglobin, It cannot be transported by the blood to the tissue cells, resulting in hypoxia of the tissue cells
