What can gas poisoning damage 15

First of all, the affinity between carbon monoxide and hemoglobin is 200 300 times higher than that of oxygen and hemoglobin, so carbon monoxide is very easy to combine with hemoglobin to form carboxyhemoglobin, so that hemoglobin loses its oxygen-carrying ability and effect, causing tissue suffocation.

The ensuing consequences are mainly reflected in the toxicity to the brain, spinal cord and other central centers. In the early stage of poisoning, symptoms such as headache, dizziness, vomiting, limited movement, and numbness of limbs will appear. Mild cases may experience temporary or permanent frustration and paralysis after treatment.

In severe cases, it can lead to vegetative and even death due to severe damage to the brainstem. In addition, it can cause pulmonary edema and myocardial damage. If the patient dies, the body has a cherry-red appearance, which is due to the formation of carboxyhemoglobin.

Mild poisoning is better after treatment, and there are no sequelae. In more severe cases, drugs such as Piracetam can be taken for a long time to restore brain function, which can achieve good results. In the case of severe poisoning, if it can be treated to save lives, sequelae such as dementia, memory and comprehension loss, and limb paralysis will occur.

In general, the longer the coma, the more severe the sequelae.

Gas poisoning is the combination of carbon monoxide in the gas and the oxygen inhaled by the person, resulting in the oxygen being combined with the carbon monoxide and unable to supply the human body's needs, so that the person is hypoxic.

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.

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.

1. Generally mild gas poisoning, due to the inhalation of carbon monoxide is not much, the time is not long, as long as you can quickly leave the poisoning environment and breathe fresh air, generally in about 1-2 hours headache, dizziness, nausea, fatigue and other poisoning symptoms can be relieved, 1-2 days can be restored, usually no sequelae.

2. Patients with moderate gas poisoning can basically wake up from a coma after a timely and effective **, although there may be symptoms such as sluggishness, apathy, drowsiness, etc., but most of them can recover symptoms after a few days of potato deficiency, without obvious complications and sequelae.

3. Severe poisoning events caused by high coarse fissure concentration of carbon monoxide or continuous inhalation for a long time can often cause pneumonia, pulmonary edema, myocardial damage, heart rate disorder or conduction block, as well as complications such as high fever and peripheral neuritis.

4. Some patients suddenly become stupid or even become dementia after two weeks to two months after being awake from poisoning, which is called carbon monoxide poisoning encephalopathy. The reason for this is that although the function of the brain is restored after poisoning, it is caused by the continued deterioration or even necrosis of brain cells due to factors such as hypoxia and edema, and the nutrition of brain cells has not been improved in time.

The main manifestations are sluggishness, dull expression, sluggish movements, more taciturnity, varying degrees of decline in intelligence, decreased memory, severe loss of bowel and bowel control, and consciousness disorders.

The main manifestations are disordered behavior, incoherent speech, crying and laughing, random urination, and behavior that is different from ordinary people. Often self-talking, loss of orientation.

The main manifestations are mainly motor dysfunction and accompanied by mental decline in Iwate, which is manifested by unsteady walking gait, small broken steps, and stiff limb movement.
