The conversation between the two people opposite shocked everyone present.
Song Xuelin quickly raised his head, with round brown eyes: This gossip was obviously too big, and it was going to cost him no coffee.
Classmate Geng’s accurate statement is that he died of 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, the person will suffocate and die. Therefore, when the concentration of carbon monoxide in the air reaches a certain limit, the person will take a few breaths due to lack of blood.
It is possible to lose consciousness immediately and die within a few minutes of breathing.
The speed of thick smoke in a fire is five times that of fire. It is conceivable that the smoke reaches the human body much faster than the harm of fire. The smoke is full of carbon monoxide, which means that the fire may suffocate people before burning them.
.Many people who were burned to death in the fire first died of smoke poisoning and then their bodies were burned.
The fire first aid manual says that you should prevent smoke and block fires. Even if you haven't seen fire yet, you should cover your mouth and nose with a thick wet towel to filter out the smoke to prevent smoke from entering the body and escaping to a place where there is no smoke.
Because the direction in which the smoke drifts is actually the direction in which the fire spreads, the high-temperature thick smoke can form a new fire within two minutes.
Not to mention, many people don’t know that people who are saved in fires think that only the superficial burns are the most severe. In fact, the death rate from inhalation lung injury, that is, fire lungs, is extremely high.
Back to the focus of the dispute between the two classmates.
"There is no special mention of fire in emergency medicine," Wei Shangquan retorted.
Emergency medicine textbooks definitely do not talk about how to prevent fires and how to save yourself and survive in fires. This is not the content of emergency medicine.
Medicine is about the pathogenesis and treatment of diseases. Therefore, we will only talk about how to treat the injured in fires by category, such as how to treat carbon monoxide poisoning and how to treat burns. In such a chapter, several topics about fire may be mentioned.
The words let you know that there will be such patients in the fire.
How to classify and summarize how to treat fire casualties needs to be supplemented by other academic materials, or it may be up to the doctors themselves to reorganize the relevant knowledge.
Classmate Geng talked about Classmate Wei being rigid: "Don't you know how to take notes by yourself?"
Before encountering fire treatment, or even after encountering fire casualties, most doctors will not think of summarizing how to treat fire casualties. You must understand that fires are not the only ones that produce carbon monoxide patients or burn patients. Medical classification of patients is not
Divided by accident type.
Classmate Wei spoke plausibly and competed with classmate Geng: If clinical teachers don’t organize things, it means there is no need. Besides, is it wrong for me to let her run? Some people must run first. She is afraid of being burned to death or choking to death from smoke.
Gotta run.
The two classmates argued over the issue of letting people run or not.
Some students in the building couldn't wait any longer, so they ran out and started arguing after hearing their quarrel.
Are you going to let people run away?
It is hard to say whether the fire can be stopped by smoke prevention alone, and whether the people in the fire can survive the fire until they are discovered and rescued by subsequent firefighters before they are actually burned by the fire.
Theoretically speaking, the self-rescue method cited in the disaster prevention manual mentioned by Mr. Geng is an ideal state. When a person is in a crisis, it is difficult for people to accurately identify the environment suitable for running as suggested by Mr. Geng.
"We can't do what Yongzhe said. They can see the full situation of the fire scene before running away."
