When the temperature drops suddenly, everyone may take a bath, burn charcoal to keep warm, eat hot pot and barbecue after closing the doors and windows, which may cause "carbon monoxide poisoning", which is often called "gas poisoning".
Carbon monoxide is colorless and odorless, so it is difficult to be detected. The common cause of poisoning is burning charcoal for heating in a closed or poorly ventilated room. When using gas to cook hot pot, barbecue or use gas water heater, the concentration of carbon monoxide in indoor air rises due to incomplete combustion and poor exhaust gas discharge.
Symptoms of carbon monoxide poisoning
In what aspects?
Mild poisoning: there will be symptoms such as headache, dizziness, palpitation, nausea, vomiting and general fatigue. At this time, if you can open the window in time to ventilate and inhale fresh air, the symptoms will be alleviated and disappeared soon.
Moderate poisoning: sweating, irritability, unsteady walking, pale skin, vague consciousness, always feeling sleepy, sleepy and weak, and gradually entering a coma. If effective measures are taken, it can basically be cured, leaving few sequelae.
Severe poisoning: most of them are delirious, with clenched teeth, whole body twitching, incontinence, cherry red complexion, rapid breathing and pulse, rising blood pressure, arrhythmia, rales in the lungs, and possibly rising body temperature. Extremely critical patients can be in a deep coma, with weak pulse, irregular breathing, blood pressure drop, and high fever of 40 degrees Celsius. At this time, life is dying and the mortality rate is high. Even if you are lucky enough to survive, you will leave serious sequelae.
Found carbon monoxide poisoning
How to give first aid?
After carbon monoxide poisoning, the poisoned person should be carried out of the room full of carbon monoxide, transferred to a ventilated and warm place to lie flat, and the collar and belt should be untied to facilitate his breathing and smoothness.
When waiting for rescue, the unconscious poisoned person can tilt his head to one side to prevent the vomit from being inhaled into the lungs by mistake and causing suffocation.
Prevention is the most important
Now the country has entered a period of high incidence of carbon monoxide poisoning, and Chengdu CDC hereby urgently reminds you to be vigilant and do the following:
When burning coal and charcoal indoors for heating, we must keep the air circulating. Remember to put out the fire before going to bed, burn out the coal and don’t cover it.
Check the water heater and cooker at home to ensure the installation specification, and replace them in time if they are found to be damaged or leaking; Pay attention to keep good ventilation when taking a bath, and never let the water heater and gas stove burn empty.
Do not use oil-fired generators for a long time in poorly ventilated rooms, garages, basements, etc.
When driving an air-conditioned car for a long time, be sure to open the window for ventilation, and avoid sleeping in an idle state and a closed air-conditioned car.
When eating hot pot and barbecue indoors, we should also pay attention to opening the window for ventilation. It is best not to use coal or charcoal to heat and cook hot pot.
Pay attention to several misunderstandings
1. If you don’t smell the smoke, you won’t be poisoned?
Carbon monoxide is colorless and odorless, and it may be poisoned before people realize it. Once they realize that they are poisoned by carbon monoxide, it is often too late. Although the poisoned person is conscious and wants to open the doors and windows to escape, his hands and feet are out of control, and he often cannot save himself effectively, which may eventually lead to coma or death.
2. bank up won’t be poisoned with wet coal?
Carbon monoxide is extremely insoluble in water, and water and gas are easy to form water-gas mixture at high temperature, which increases the risk of poisoning.
3, there are gaps in doors and windows will not be poisoned?
The specific gravity of carbon monoxide is smaller than that of air. If the gap between doors and windows is low, carbon monoxide is not easy to be discharged.
4, carbon monoxide poisoning rescue will be fine?
Carbon monoxide poisoning may cause sequelae of central nervous system, so we must adhere to the follow-up treatment and do not leave sequelae.
