The conversation between the two people on the opposite side shocked the people who were listening.
Song Xuelin quickly raised his head, his brown eyes round: This gossip was obviously too big, it was going to cost him his coffee.
The accurate way to describe what Geng said is that he died of carbon monoxide poisoning.
When 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, people may lose consciousness immediately after taking a few breaths due to lack of oxygen in the blood, and die within a few minutes of breathing.
The speed of smoke spreading in a fire is five times faster than the speed of fire burning. It is conceivable that smoke can reach the human body much faster than fire. Smoke is full of carbon monoxide, which means that it may suffocate people before the fire burns them. Many people who died in fires were first poisoned by smoke and then burned by the fire.
The fire emergency manual says that you should prevent smoke from blocking fire. Even if you don't see the fire approaching you, you should use a thick wet towel to cover your mouth and nose to filter out the smoke, prevent the smoke from entering your body, and escape to a smoke-free place. Because the direction of the smoke is actually the direction of the fire, and the high-temperature smoke can form a new fire within two minutes.
Not to mention, many people don’t know this and think that those who are rescued from a fire only have the most severe burns on the surface of their bodies. In fact, the mortality rate from aspiration lung injury, or lung death in a fire, is extremely high.
Let’s return to the focus of the dispute between the two students.
"There is no specific mention of fire in emergency medicine," Wei Shangquan retorted.
...
...
Emergency medicine textbooks definitely do not talk about how to prevent fires or how to save yourself and survive in a fire. This does not belong to the content of emergency medicine.
Medicine is about the pathogenesis and treatment of diseases. Therefore, it will only talk about how to treat the wounded in fire in different categories, such as how to treat carbon monoxide poisoning and burns. In such a chapter, the word "fire" may be mentioned to let you know that such patients will appear in fires.
How to classify and summarize how to treat fire victims needs to be supplemented by other academic materials, or perhaps the doctors themselves need to reorganize the relevant knowledge.
Geng said of Wei’s rigidity: “Can’t you take your own notes?”
Before encountering fire rescue, or even after encountering fire victims, doctors generally do not think of summarizing how to treat fire victims. You have to understand that it is not only fires that produce carbon monoxide patients or burn patients. Medical classification of patients is not based on the type of accident.
Wei argued with Geng: "If the clinical teachers don't organize their things, it means there is no need for them. Besides, is it wrong for me to ask her to run? If someone wants to run, they must run first. If they are afraid of being burned to death or choked by smoke, they must run even more."
The two students were arguing over whether or not to let people run.
Some students in the building couldn't wait any longer and ran out to hear them quarreling and started arguing with them.
Should we let people escape or not?
It is hard to say whether smoke and fire blocking alone can stop the fire, and whether the people in the fire can survive until they are discovered and rescued by the firefighters who arrive later before they are actually burned by the fire.
Theoretically, the self-rescue method cited in the disaster prevention manual that Geng mentioned is ideal. However, when people are in danger, it is difficult to accurately identify whether the environment is suitable for running as Geng suggested.
"They can't do what Yongzhe said and see the full situation of the fire scene before running away."
