The poisoning incident in Xuzhou Hotel caused 1 death and two people were injured. What is the specific cause of poisoning?

A suspected carbon monoxide poisoning accident occurred in the local Boden Windham Hotel in Xuzhou, Jiangsu. The cause of poisoning may be the failure of the boiler piping system in the hotel, which led to some toxic gases entering the air conditioning and ventilation system. The specific source is unknown. Accident investigation and aftermath are being carried out in an orderly manner according to law. At present, 1 person has died and 2 people have been hospitalized for poisoning. One of them is still in danger and is being rescued in the intensive care unit.

This hotel is closed. A working group composed of local safety supervision department and fire department is investigating the cause of the hotel accident. Carbon monoxide CO is the most common asphyxiating gas, commonly known as gas. TA is colorless, odorless and non-irritating, but it is flammable and explosive. Inhalation of carbon monoxide can cause different degrees of poisoning symptoms in human body. High concentrations of carbon monoxide in the air may also cause an explosion. Colorless and tasteless, invisible and intangible, but enough to kill people. Eat charcoal-burning copper hot pot in a closed environment, take a bath with a gas water heater in a room with closed doors and windows, and blow air conditioning in a car with closed windows. This deadly invisible killer is approaching quietly and is called an easy executioner.

When excessive carbon monoxide is inhaled, it will compete with oxygen for respiratory tract, and its strong preemptive ability will seize the transportation space of oxygen, resulting in human hypoxia. There will be dizziness, chest tightness, nausea and other symptoms, which will seriously affect brain tissue and even death. After carbon monoxide enters the human body, it will stubbornly combine with hemoglobin of human red blood cells. After hemoglobin is combined with carbon monoxide, it can no longer be combined with oxygen, thus reducing the oxygen carrying capacity of human blood and forming hypoxia.

Severe carbon monoxide poisoning can cause complications such as lung fever, pulmonary edema, heart disease and aspiration pneumonia. After treatment, it often leaves sequelae such as dementia, decreased memory and understanding, and limb paralysis, which causes serious harm to patients. If you pay attention to local or online pharmacies, you will find that many products are marked to increase the content of nitric oxide in the human body. These products achieve this goal by providing a large amount of arginine.
