On January 20, the Great Cold Festival was ushered in. When the coldest time of the year comes, everyone will adopt various tactics to resist the cold. Jinan disease control experts remind that since the beginning of winter, non-occupational carbon monoxide poisoning incidents have occurred frequently, and everyone should always be vigilant against this "silent killer" while enjoying the joy of family fun.

According to reports, home coal heating is the main cause of non-occupational carbon monoxide poisoning. Every year, Jinan monitors hundreds of cases of non-occupational carbon monoxide poisoning, most of which are attributed to household coal heating. There are obvious seasonal changes in non-occupational carbon monoxide poisoning events, mainly concentrated in January-March and November-December.

Poisoning events caused by home coal heating have obvious 24-hour time distribution characteristics, and the reported incidence time period is concentrated in 06:00-08:59. The main reasons for the occurrence are poor ventilation and insufficient oxygen supply during coal burning, which produces a large amount of carbon monoxide stored indoors, and carbon monoxide is a colorless, odorless, non-irritating gas, making it difficult to detect.

"Carbon monoxide in the environment is produced by carbon-containing substances when they are not completely burned, mainly from anthropogenic activities. According to the degree of poisoning, it is divided into mild, moderate and severe types. According to experts from the Jinan Center for Disease Control and Prevention, the poisoning time of mild poisoning is short, and the concentration of carboxyhemoglobin in the blood is 10%-20%. Symptoms are mainly headache, dizziness, tinnitus, dizziness, nausea, vomiting, limb weakness, and even brief fainting, and angina in patients with pre-existing coronary heart disease. After quickly leaving the poisoned environment and breathing fresh air, the symptoms can disappear quickly, and there are generally no sequelae.

Moderate poisoning has a long toxicity time, and the concentration of carboxyhemoglobin in the blood is 30%-40%. On the basis of mild symptoms of intoxication, coma or prostration may occur. Patients may present with cherry red skin, flushing, hyperhidrosis, rapid pulse, confusion, unsteadiness, confusion, drowsiness, decreased judgment, hallucinations, and sluggishness to light and corneal reflexes. Patients at this stage must be rescued in time, such as rescue can be quickly awakened, fully recovered within a few days, generally no sequelae symptoms.

The poisoning of severe poisoning was found too late, inhaled carbon monoxide was too much, and the concentration of carboxyhemoglobin in the blood has reached more than 50%. The patient presents a state of deep coma, with significant weakening or disappearance of various reflexes, cold extremities, increased body temperature, decreased blood pressure, urinary and urinary incontinence, sweating, and respiratory depression. Patients with severe poisoning have a high mortality rate, and survivors may have serious sequelae.

Therefore, experts from the Jinan Municipal Center for Disease Control and Prevention remind that coal-fired heating in winter must use heating appliances with good airtightness, and frequent inspections are carried out to ensure that their flues are unobstructed, and indoor ventilation should be often ventilated. If you have suspected symptoms of carbon monoxide poisoning in your home, please bring them to the doctor as soon as possible to reduce health losses.
