What about gas poisoning?

Gas poisoning refers to carbon monoxide poisoning because carbon monoxide is colorless and tasteless. Once it is produced, it is not easy for us to find it. Especially in sleep, carbon monoxide will unconsciously invade the respiratory tract, enter the blood through gas exchange in alveoli, and spread to the whole body, causing poisoning. Because it will affect the absorption and transportation of oxygen, light people will feel dizzy, tinnitus, dizziness and limb weakness after poisoning; Heavier people will have nausea, vomiting, boredom and even nerve paralysis and can't move; In severe cases, it will cause coma, convulsion, incontinence, dyspnea and so on. When the combination of carbon monoxide and hemoglobin in blood reaches 70% ~ 80%, people will die quickly.

In case of gas poisoning, we can refer to the following items:

1. Ask the patient to leave the poisoned environment as soon as possible, move to an open and ventilated place, and immediately open the doors and windows for ventilation. It must be noted that before ensuring the ventilation of the air in the poisoned environment, it is forbidden to use equipment that is prone to open flames and sparks, such as electric lights, telephones, mobile phones, televisions, gas stoves, flashlights, candles, etc. To prevent carbon monoxide from exploding in an open flame with high concentration.

2. Loosen the button, keep the respiratory tract unobstructed, remove the mouth and nose secretions, ensure that patients have spontaneous breathing, and fully give oxygen.

3. Patients should rest quietly, so as not to increase the burden of heart and lungs and increase the consumption of oxygen after activities.

4. The unconscious poisoned patient must be carried out of the poisoned environment as soon as possible, and the patient's breathing, pulse and blood pressure should be checked in the shortest time, and emergency treatment should be carried out according to these conditions.

5. If the respiratory heartbeat stops, artificial respiration and cardiac compression should be performed immediately.

6. After the condition is stable, escort the patient to the hospital for further examination and treatment as soon as possible. But please remember that even if the patient is out of danger due to mild poisoning or mild symptoms, he should go to the hospital for examination as soon as possible and receive glucose, vitamin C and oxygen inhalation treatment to reduce the risk of sequelae. Remember to avoid being careless because you are temporarily out of danger. Not going to the hospital for treatment will lead to serious sequelae such as memory loss and dementia.

7. Strive for hyperbaric oxygen chamber treatment as soon as possible to reduce sequelae. Even if it is mild or moderate, hyperbaric oxygen chamber treatment should be carried out.

In order to nip in the bud, we should actively prevent gas poisoning: we must use coal stoves reasonably. Public security organs deal with a large number of gas poisoning incidents every year. Experienced police reminded residents that when installing stoves (including floor heating), they should check whether the stoves are in good condition. If they find problems such as damage, corrosion and air leakage, they should replace and repair them in time. Check whether the flue is unblocked and blocked; An elbow should be installed at the air outlet of the chimney, and the outlet should not face north to prevent gas from flowing backwards due to strong wind; Chimney joint should be connected firmly along the stubble (crevasse down, fine mouth up) to prevent air leakage; A fan bucket must be installed indoors. Always check whether the air hopper and flue are blocked and clean them in time. Before going to bed every night, check whether the fire is sealed, whether the cover is tight and whether the air door is open.

In addition, it is suggested to install carbon monoxide gas alarm in places where carbon monoxide gas may be produced. When the carbon monoxide gas in the air exceeds the standard, it can give an audible and visual alarm to remind people to take hedging measures as soon as possible.
