  Song Xuelin raised his head quickly, his brown eyes were round: This gossip is obviously too big, and it will kill him to drink coffee.

   Geng’s words should be called death by carbon monoxide poisoning.

   After carbon monoxide is inhaled into the human body, it combines with hemoglobin to form carboxyhemoglobin. When the blood contains 50% carboxyhemoglobin, people will suffocate and die. Therefore, when the concentration of carbon monoxide in the air reaches a certain limit, a person may lose consciousness immediately after taking a few breaths due to the lack of oxygen in the blood, and die within a few minutes of breathing.

   In the fire, the speed of the smoke is five times that of the fire. It is conceivable that the smoke reaches the surrounding of the human body far faster than the harm of the fire. The thick smoke is full of carbon monoxide, which means that the fire may suffocate people before they reach them. Many people who were burned to death in the fire were first killed by smoke poisoning and then burned their bodies.

  In the fire first aid manual, it is said that it is necessary to prevent smoke and stop the fire. Even if you haven\'t seen the fire close to you, you should use a thick wet towel to cover your mouth and nose to filter out the smoke to prevent the smoke from entering the body and fleeing to a place where there is no smoke. Because the direction of the smoke is actually the direction of the fire, the dense smoke with high temperature can form a new fire within two minutes.

   Not to mention, many people do not know that the only people who are rescued in the fire are the most severe burns on the body surface. In fact, the death rate of inhalation lung injury, that is, the fire lung, is extremely high.

   Back to the focus of the dispute between the two students.

   "Fire is not specifically mentioned in emergency medicine." Wei Shangquan retorted.

  Emergency medicine textbooks definitely do not teach how to prevent fires and how to save themselves and survive in fires. This is not the content of emergency medicine.

  Medicine is about pathogenesis and treatment. Therefore, we will only talk about how to treat the wounded involved in the fire, such as how to treat carbon monoxide poisoning and how to treat burns. In such a chapter, the word fire may be mentioned to let you know that it is a fire There are such patients.

  How to classify and summarize how to treat fire casualties should be supplemented by other academic materials, perhaps by doctors who reorganize the relevant knowledge context.

   Geng said that Wei was rigid: "Can\'t you take notes by yourself?"

   Before a fire treatment is encountered, or even after encountering a fire casualty, most doctors do not think of summarizing how to treat the fire casualty. Understand that it\'s not just fires that produce carbon monoxide patients or burn patients. Medicine does not classify patients by accident type.

  Student Wei is plausible, and he is more energetic than classmate Geng: the things that other clinical teachers do not organize indicate that there is no need for this. Besides, is it wrong for me to let her run? Some must run first. Afraid of being burned to death and choked to death by smoke, I had to run.

  The two classmates were arguing about whether to run or not.

   Some of the students in the building couldn\'t wait, and ran out to hear their quarrels and arguing.

   Let people run or not?

   It is hard to say whether the fire can be blocked by smoke prevention alone, and whether the people in the fire can persist until they are found and rescued by the firefighters who come after the fire is really burned.

   In theory, the self-rescue method in the disaster prevention manual cited by Geng is an ideal state. When people are in critical condition, it is difficult for a strong man to accurately identify the environment suitable for running as suggested by Geng.

   "They can\'t do what Yongzhe said they can see the full situation of the fire scene before running."
