The cold wave is coming, and the doors and windows are closed tightly to prevent carbon monoxide poisoning

\”The temperature drops sharply. After closing the door and closing the window, you should prevent carbon monoxide poisoning when you take a bath, warm, eat hot pot, and barbecue.\” Huang expansion, deputy director and deputy chief physician of the emergency department of Hunan Aerospace Hospital.

The reporter learned that the emergency department of the major hospitals of the provincial capital since the winter has been treated with patients with carbon monoxide poisoning. Most of these patients were dizziness and vomiting when they were admitted to the hospital. Some because the weather is cold, the gas valve in the home is not tight, and all doors and windows are closed. After waking up in the morning, dizzy and vomit; some take a bath in the bathroom at night, wash it for a long time, and then suddenly call for help; People appear unconscious … After the 120 ambulance was sent to the hospital, they were diagnosed with carbon monoxide poisoning.

Huang expanded the army that carbon monoxide poisoning was poisoned due to the inhalation of carbon -containing substances when it was incomplete. Carbon monoxide is colorless, tasteless, and irritating, and it is difficult for patients to detect early in the early days. Once it is inhaled, it is 200-300 times higher than the close combination of hemoglobin than the kinship of oxygen and hemoglobin. It is mainly hypoxia, causing tissue to suffocate. Carbon monoxide poisoning has a toxic effect on tissue cells in the whole body, especially the most serious impact on the cerebral cortex.

Mild poisoning will have symptoms such as headache, dizziness, panic, nausea, vomiting, systemic weakness. If you can open the window in time to ventilate and inhale fresh air, the symptoms will quickly reduce and disappear.

During moderate poisoning, there may be sweat, irritability, unstable walking, pale skin, blurred consciousness, always feeling sleeping, sleepy and weak, and gradually enter a coma. It can be cured and rarely leaves sequelae.

Those with severe poisoning are mostly unclear, the teeth are closed, the whole body is twitching, the stool is incontinence, the lips are red red, the breathing and pulse increased, the blood pressure rises, the arrhythmia is uneven, the lungs are 啰 in the lungs. Sound, body temperature may rise. Extremely critical areas can sustainable deep coma, weak pulse, irregular breathing, blood pressure decrease, and high fever can also occur at 40 ° C. At this time, the poisoning mortality rate is high. Even if you are lucky enough

High -pressure oxygen treatment is an effective means of clinical use. In high -pressure environments, the combination of oxygen and hemoglobin has improved significantly, thereby enhancing the ability of hemoglobin to compete with carbon monoxide. This not only helps to quickly dissolve carbon oxygen protein, promote the discharge of carbon monoxide, but also increase the physical oxygen content in plasma, and quickly correct hypoxemia. In addition, high -pressure oxygen can also reduce cerebral edema, reduce intracranial pressure, improve the microcirculation and metabolic status of brain tissue, thereby effectively prevent the occurrence of delayed encephalopathy.

The Huang expanded army reminded that the proportion of carbon monoxide is smaller than the air. If the position of the doors and windows is low, carbon monoxide is not easy to discharge, so pay attention to the indoor air circulation. The temperature drops sharply, and the indoor heating should keep the air circulation. Remember to ensure that the fire is extinguished before going to bed. Hot at homeWater heaters and cookers are used to ensure safe use. If you find damaged and leakage, contact relevant departments in time to replace the maintenance; pay attention to maintaining a good ventilation state when bathing, and cut the water heater and gas stove to burn. Do not use fuel generators for a long time in poor ventilation indoor, garage, basement and other spaces. Do not sleep in a closed air -conditioned car. When eating hot pot and barbecue in the room, pay attention to opening the window to ventilate.
