In winter, the mainland has entered a period of high incidence of carbon monoxide poisoning:
At the beginning of the new year of 2022, the mother and the 4-year-old child were poisoned to death after burning charcoal at home for heating, and 2 children died of poisoning by bathing alone in the home using a water heater...
Entering the cold winter, the temperature plummeted, everyone in the closed doors and windows, bathing, charcoal heating, hi hot pot, barbecue may cause "carbon monoxide poisoning", is often said "gas poisoning".
Carbon monoxide is colorless and odorless, and is difficult to detect.
The common cause of poisoning is to burn charcoal for heating in a closed or poorly ventilated room, and when using a gas hot pot to cook a hot pot, make a barbecue or use a gas water heater, the concentration of carbon monoxide in the indoor air is increased due to incomplete combustion and poor exhaust emissions.
Carbon monoxide poisoning
In what ways are the symptoms?
Mild poisoning: there will be headache, dizziness, palpitation, nausea, vomiting, fatigue and other symptoms. At this time, if you can open the window for ventilation in time and inhale fresh air, the symptoms will quickly alleviate and disappear.
Moderate intoxication: sweating, irritability, walking unsteadily, pale skin, confusion, constant feeling of not waking up, drowsiness and fatigue, and gradually enter a coma. If effective measures are taken, it can be basically cured, leaving few sequelae.
Severe poisoning: mostly confused, teeth closed, twitching of the whole body, incontinence, face and lips appear cherry red, breathing and pulse increased, blood pressure rises, arrhythmia, rales in the lungs, and body temperature may rise. People with extremely critical conditions can continue to be in deep coma, with weak pulses, irregular breathing, decreased blood pressure, and may also have a high fever of 40 degrees Celsius, at which time life is in danger and mortality is high. Even if you are lucky enough not to die, you will be left with serious sequelae.
How to give first aid when carbon monoxide poisoning is found?
After carbon monoxide poisoning occurs, the poisoned person should be quickly carried out of the carbon monoxide-filled room, transferred to a ventilated and warm place to lie flat, and untied the collar and belt to facilitate his breathing and smoothness.
While waiting for rescue, a comatose poisoned person can tilt his head to one side to prevent vomit from being inhaled into the lungs and causing suffocation.
Carbon monoxide poisoning, prevention is the most important!
Now that the country has entered a period of high incidence of carbon monoxide poisoning, Chengdu Disease Control is here to urgently remind, please be vigilant and do the following:
01
Indoor coal burning, charcoal heating must maintain air circulation, remember to ensure that the fire is extinguished before going to bed, coal should be burned out, do not cover.
02
Check the water heater and stove in the home to ensure that the installation specifications, such as found to be damaged, air leakage should be replaced in time; pay attention to maintaining good ventilation when bathing, and do not let the water heater and gas stove burn empty.
03
Do not use fuel generators for long periods of time in poorly ventilated rooms, garages, basements, etc.
04
In the car with air conditioning open for a long time, be sure to open the window for ventilation, and avoid sleeping in the idle state and in the closed air conditioning car.
05
When eating hot pot and barbecue indoors, it is also necessary to pay attention to opening the window for ventilation, and it is best not to use coal and charcoal to heat the hot pot.
Be aware of a few misunderstandings
Can't be poisoned without smelling smoke?
Carbon monoxide is colorless and odorless, and it can be poisoned before people are aware of it, and 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, the hands and feet have not listened to the call, often unable to carry out effective self-help, and may eventually lead to coma or death.
Sealing a fire with wet coal will not cause poisoning?
Carbon monoxide is extremely insoluble in water, and water and gas are easy to form water and gas mixtures at high temperatures, increasing the risk of poisoning.
If there are gaps in doors and windows, you will not be poisoned?
The specific gravity of carbon monoxide is smaller than that of air, and if the position of the gap between doors and windows is low, carbon monoxide is not easy to discharge.
Carbon monoxide poisoning rescued will be fine?
Carbon monoxide poisoning may cause central nervous system sequelae, and it is necessary to adhere to follow-up treatment and not leave sequelae.
