The holiday is coming, the outdoor temperature is low in winter, many friends choose to set up a charcoal stove at home, put a teapot, red oranges, three or five friends sit around the table, the tea fragrance is curling, the fireworks are dense, "cooking tea around the stove" will easily grasp the sense of atmosphere, however, the warm scene of this stove warm tea fragrance is hidden danger, recently there have been a number of carbon monoxide poisoning incidents caused by the use of charcoal fire "cooking tea around the stove", from November to March of the following year, it is the high incidence season of carbon monoxide poisoning, how can we avoid the occurrence of such events?How to administer first aid if a poisoned patient is found?We invited Long Hongyu, the attending physician of hyperbaric oxygen from Chengdu First People's Hospital, to answer.
Dr. Long Hongyu, Hyperbaric Oxygen of Chengdu First People's Hospital.
What is carbon monoxide poisoning?
According to Dr. Long, carbon monoxide is a colorless, odorless, and non-irritating asphyxiating gas, and it is also a mysterious "killer", which hurts people invisibly. Carbon monoxide (CO) poisoning, commonly known as gas poisoning, is a hypoxic disease caused by inhalation of higher concentrations of CO, and can be manifested as toxic asphyxia in severe cases.
When the concentration of carbon monoxide in the air reaches 004% to 0At 06%, it only takes a few minutes for mild poisoning to appear. CO is a toxic gas, once it enters the body, it will quickly combine with hemoglobin in the blood to form carboxy-hemoglobin (COHB), which affects the transportation of oxygen in the human body and hinders the utilization of oxygen, resulting in hypoxia of body tissues, especially the brain and heart sensitive to hypoxia, which are most harmful, and can lead to death in severe cases.
As the temperature drops, in addition to "cooking tea around the stove", eating hot pot, barbecue, heating indoors, cooking with gas with doors and windows closed, parking and blowing air conditioners with windows closed, etc., seemingly ordinary behaviors may be the "culprit" of carbon monoxide poisoning.
How can I prevent carbon monoxide poisoning?
Avoid burning carbon-containing fuels (coal, charcoal, etc.) for cooking and heating in unventilated places, and pay attention to opening windows for ventilation and maintaining indoor air circulation
The old residential community should pay attention to whether there is a gas leak and whether the smoke exhaust is unobstructed
Avoid installing air conditioners and natural gas water heaters indoors
Avoid sleeping in the car with the air conditioner closed when the vehicle is stopped, so as to prevent carbon monoxide from accumulating in the car
Pay attention to strengthen fire prevention measures, fire smoke contains a large amount of CO, if possible, alarms, fire extinguishing equipment and escape equipment can be installed at home
How can I help myself or others with carbon monoxide poisoning?
When you perceive suspected carbon monoxide poisoning, cut off the poisoning gas**, immediately leave the environment or open doors and windows, breathe fresh air as soon as possible, feel fatigue, shortness of breath, chest pain, etc., and call 120 first aid** for emergency help.
If you find that your companion is unable to breathe, loosen your clothes, keep your airway open, clear mouth and nose secretions, and tilt your head to one side to prevent aspiration of vomit. If cardiorespiratory arrest is found, CPR should be performed immediately.
What are the main ways of carbon monoxide poisoning?
The key interventions for carbon monoxide poisoning are timely removal of the source of carbon monoxide and the provision of high-flow oxygen.
Atmospheric oxygen**: suitable for on-site first aid, transport process, emergency rescue, through oxygen inhalation appliances with high flow rate.
Hyperbaric oxygen** (HBOT): It is currently an effective clinical method to accelerate and promote the dissociation of carbon monoxide from hemoglobin. Hyperbaric oxygen is the first choice for carbon monoxide poisoning, the principle of action is to inhale high-purity oxygen in an environment higher than one atmosphere, increase the oxygen content in the blood, promote the discharge of carbon monoxide, can make headache, dizziness, nausea, fatigue and other poisoning symptoms be quickly relieved, significantly improve the survival rate and ** rate of carbon monoxide poisoning patients, and reduce the incidence of late-onset encephalopathy.
Dr. Long Hongyu also specially reminded everyone that winter is the season of high incidence of carbon monoxide poisoning, and the key to preventing carbon monoxide poisoning is to avoid using gas, charcoal and other fuels in a closed space, and regularly open windows to maintain good ventilation.
