From:Beijing Municipal Health Commission


Recently, the 120 center of Beijing has received many calls of carbon monoxide poisoning incidents. Most of the accidents are caused by residents in the cottage using coal fire for heating, causing carbon monoxide leakage and poisoning. Carbon monoxide is a colorless, odorless gas that many people are totally unconscious when it leaks, which causes poisoning. What should we do when facing the accident?

Acute carbon monoxide poisoning is mostly caused by stove fire in the house. The wrong installation, blockage, air leakage, downwind, and other troubles of chimney may lead to improper exhaust. In addition, if the doors and windows in the house are closed, the gas generated by the fire cannot be discharged in time, causing carbon monoxide poisoning. Another common situation is that a gas water heater may cause carbon monoxide poisoning in the case of poor ventilation. The symptoms of poisoning could be divided into three degrees. The symptoms of mild poisoning cover headache, dizziness, nausea, vomiting, weakness of the limbs, etc. Moderate poisoning is shown on the basis of mild symptoms, resulting in gradual disturbance of consciousness and even coma. The typical performance of moderate monoxide poisoning is that the lips are red like cherry. Severe monoxide poisoning usually causes deep coma and gatism.

When you find a person who is poisoned, you should move the person out of the poisoning place and open the door and window to ventilate immediately. When you get to the outdoors, it is advised to keep the patient warm and ensure that the patient’s airway is unblocked. You can also give the patient oxygen and call the emergency number 120. While waiting for rescue, you should monitor the patient’s conditions.
