Winter is the season of high incidence of carbon monoxide poisoning, a common colorless, odorless, non-irritating harmful gas, known as the "invisible killer". The District Gas Poisoning Prevention Coordination Leading Group reminds the public that the weather is cold, please take precautions and beware of carbon monoxide poisoning.
Shengli Street held an on-site work meeting on the prevention of carbon monoxide poisoning in the Yibin Street community.

From November this year to March next year, the District Gas Poisoning Prevention Coordination Leading Group will carry out four "warm" actions, and during the high incidence of accidents, carry out centralized household publicity and inspection in areas that have not completed the "coal-free" transformation, check and update the basic ledger, sign the safety responsibility letter for the prevention of gas poisoning from house to house, and post safety stickers on stoves one by one to enhance the public's awareness of prevention.
What is carbon monoxide poisoning?
Carbon monoxide poisoning is a product of incomplete combustion of carbon-containing substances, which is caused by respiratory inhalation, commonly known as gas poisoning. The affinity between carbon monoxide and hemoglobin is 200 to 300 times higher than that of oxygen and hemoglobin, so carbon monoxide is very easy to combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying ability and effect, causing tissue suffocation. It has a toxic effect on tissue cells throughout the body, especially on the cerebral cortex.
What are the symptoms of carbon monoxide poisoning?
Mild poisoning: severe headache, dizziness, weakness of limbs, palpitation, dizziness, nausea, vomiting, unsteady gait, mild impaired consciousness. Patients with pre-existing coronary artery disease present with angina pectoris. After quickly getting out of the poisoned environment and breathing fresh air, the symptoms can disappear quickly, and there are generally no sequelae.
Moderate poisoning: In addition to the above symptoms, there can also be flushing, cherry red lips, rapid pulse, sweating, irritability, pale mucous membranes, shallow to moderate coma, dulled pupil reflex to light, corneal reflex and tendon reflex, respiration and blood pressure can change. If the rescue is timely, it can wake up quickly, recover completely within a few days, and generally have no sequelae.
Severe poisoning: on the basis of the clinical manifestations of mild and moderate poisoning, there is a deep coma, the coma state can last for several hours or days, trismus, incontinence, cerebral edema, pulmonary edema, shock, arrhythmia and other symptoms may occur. Patients with severe poisoning have a high mortality rate, and those who survive may have severe sequelae.
To prevent carbon monoxide poisoning, don't do these things:
1.In winter, coal stoves are used for heating, doors and windows are closed, and smoke exhaust is poor.
2.The coal stove does not have a chimney or the chimney is blocked.
3.The chimney is facing the tuyere, and the gas flows into the chamber in reverse.
4.There is no ventilation in the room.
5.Leakage of liquefied stoves and leaks of gas pipes.
6.Use a gas water heater and build it in the same house as the bathroom.
7.Turn on the air conditioner when parking for long periods of time.
How to help someone with carbon monoxide poisoning?
The District Gas Poisoning Prevention Coordination Leading Group reminds the public not to panic too much when they find a person with carbon monoxide poisoning, and to open doors and windows for ventilation on the premise of keeping warm to ensure that the poisoned person is in an environment with fresh air circulation.
It is necessary to pay attention to the different measures taken for people with different degrees of poisoning. For poisoned people who are delirious but have an unobstructed respiratory tract, the head should be tilted to one side to prevent the poisoned person from inhaling vomit into the respiratory tract and causing suffocationFor those who are comatose or have convulsions, they can be pressed to stimulate the acupuncture points such as Renzhong, Shixuan, and Yongquan to wake them upRescue respiration should be given immediately to those who have stopped breathing. When taking these measures, the actual situation of the patient's condition should be considered, and for the emergency, it should be sent to the hospital as soon as possible, so as not to miss the best treatment time and cause greater harm.
