Use gas to keep the fire in a closed room. Why is it sometimes poisoned?

In some coal-producing areas, families with relatively poor economic conditions may still use coal for heating. The biggest advantage of heating with coal is that it is economical and practical. It is inconvenient to use coal for heating at home, and it may also make the home dirty. The biggest hidden danger of heating with coal is gas poisoning.

If the doors and windows at home are not ventilated in time, it may cause gas poisoning at home, especially for some elderly people. Because the elderly can't use the baking tray, they don't have a strong sense of self-prevention. They may be afraid of the cold when sleeping, and close the doors and windows, which may easily lead to gas poisoning.

Gas poisoning is also called carbon monoxide poisoning. If people are slightly poisoned, they may feel sleepy. At this time, people's consciousness is vague, and they still have a little consciousness before going to sleep, but they will soon go to sleep.

This is also the reason for the high mortality rate of gas poisoning, because people may be sleepy before they realize that they are poisoned, and even after they realize that they are poisoned, their consciousness is not awake. Few people open doors and windows to ventilate after realizing that they have been poisoned by gas. Generally, people are slightly poisoned, and then they will gradually turn into moderate poisoning and then enter severe poisoning.

So what are the signs of people before gas poisoning? 1. Mild poisoning: The symptoms of people with mild gas poisoning are nausea, palpitation and weakness of limbs. Generally speaking, they are still conscious and may faint briefly. If it's mild poisoning, it's best to deal with it, because at this time, just put the poisoned patient in the vent and let the gas poisoned patient breathe fresh air, and the patient can recover in time. Generally, people with moderate poisoning will not leave any sequelae.

2, moderate poisoning: people with moderate gas poisoning are relatively light, because patients with moderate poisoning will not leave any sequelae as long as they are treated in time, and patients with moderate poisoning should be sent to the hospital in time. Patients with moderate poisoning will have symptoms of sweating and even walking unsteadily.

3. Severe poisoning: People with severe gas poisoning are more serious. The symptoms of patients with severe gas poisoning are loss of consciousness, severe coma, incontinence and soon death. Even if they don't cause death, they may leave serious sequelae, such as paraplegia and dementia.

Gas poisoning is light and heavy. Generally speaking, prevention is the priority. If you use coal for heating at home, you must pay attention to ventilation, otherwise it may cause adverse consequences.
