News on January 7 (YMG Media Reporter Li Junling, Correspondent Wu Mingshun Zhang Qing) Winter is a period of high incidence of carbon monoxide poisoning. At about 21:00 on January 3, the dispatcher of the 120 emergency command center in Yantai received a call from a village in Laishan who needed an ambulance, stating that his family and children were in a coma and had symptoms of refractory symptoms. When the dispatcher heard of this situation, considering that it is currently in the winter heating season, and two people have the same symptoms at the same time, the dispatcher immediately asked whether there is any odor in the home, whether there is gas, etc. Get out of the environment, open windows to ventilate and other first aid measures, and dispatch an ambulance immediately. Then the ambulance arrived at the scene, and the emergency doctor also confirmed the dispatcher's preliminary judgment through a physical examination, and then the two patients were sent to the hospital for further treatment.

120 emergency experts said that carbon monoxide is colorless and tasteless, it will invade the human respiratory tract unknowingly, enter the blood through the gas exchange of the alveoli, and spread throughout the body, combine with the red blood cells in the blood, so that the red blood cells can no longer be combined with oxygen, and the oxygen content in the blood Significant decline, thus making the human body hypoxia, causing poisoning. The time of onset of symptoms of carbon monoxide poisoning and the severity of the poisoning are closely related to the indoor concentration of carbon monoxide, as well as the age of the poisoned person. Young people are more sensitive than the elderly. Pregnant women, obese people and people with chronic heart and lung diseases are also prone to poisoning. The central nervous system is most sensitive to hypoxia, so it is the first to be involved to produce symptoms of poisoning. Mild poisoning will cause headache, dizziness, palpitation, nausea, and vomiting. If you leave the poisoning environment in time, you will get better soon after inhaling oxygen or fresh air; the above symptoms of moderate poisoning can be aggravated, and your complexion will be flushed, and your lips will be cherry red. Sweating, irritability, and gradual coma; severely poisoned patients are unconscious, unconsciousness, incontinence, cold extremities, dilated pupils, decreased blood pressure, weak or stopped breathing, stiffness or paralysis of limbs, and myocardial damage on ECG examination Or arrhythmia, after active rescue, lucky survivors often leave serious sequelae, such as paralysis, dementia, convulsions, mental disorders and so on. The longer the coma, the more and more severe the sequelae.

The 120 emergency command center of Yantai City reminds the general public: Winter is the season of high incidence of carbon monoxide poisoning. Households without central heating, especially in rural areas, are still indispensable to burn coal for heating. However, if used improperly, carbon monoxide poisoning is prone to occur. The air hopper must be installed correctly for coal heating, and attention must be paid to ventilation. If a patient with carbon monoxide poisoning is found, get it out of the poisoned environment as soon as possible, open doors and windows immediately, circulate the air, and call 120 emergency number for rescue in time.
