"Oh? Have you been bitten by a poisonous snake?" Liu Tichi looked cold. In Liu Tichi's heart, what is a man? He doesn't cheat and is open and honest. Ma Ling has pretended to be dizzy twice in front of her, so Liu Tichi has always looked down on Ma Ling. Man, what is the thing under his crotch used for? He can't even hold on to the long-distance running and play fake deaf?

"Yes, what?" Ma Shen said unhappy when he heard Liu Chou's shy tone.

"Not it? I'm just giving you an example. How did you get first aid at that time?" Liu Tie-shi's expressionless face.

"No first aid." Ma Shen sneered: "At that time, I went home slowly and had a meal. I went to the hospital for a check-up under the pressure of my parents."

Ye Xiao was stunned.

Ye Xiao was clearly watching the situation at that time. After the horse was bitten, he shouted, "It's terrible, am I going to die?" He was so desperate that Ye Xiao quickly called 120 for emergency calls, wishing he could have a pair of wings and fly to the hospital immediately, and use the highest medical facility to check it out, and eliminate all the snake venom to prevent future troubles.

People are afraid of death, and so is the horse spirit.

"I am afraid that the one who bites you is just an ordinary snake, but your shallowness treats it as a poisonous snake, right?" Liu Ti looked at Ma Ling coldly and looked at everyone: "Did you have bitten a poisonous snake? You can also tell from the symptoms. Viper snakes are generally divided into nerve venom and blood venom and rare cytotoxicity. Let me give you a few examples. Nerve venom-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The people below whispered, all of whom were talking about poisonous snakes, those who had seen that kind of poisonous snake, and what had been heard on TV. Especially Ma Ling, it seemed that he wanted to deliberately fuck Liu Chichi. He did not speak in a low voice, but spoke in an ordinary voice, which made his voice the most obvious in the classroom.

"Viral snakes are very common in the wild. As soldiers, survival in the wild is an indispensable experience in the future. I hope you listen to me well. I will not be sure to use all of these, but more than half of them will definitely be able to use them. Don't regret not listening carefully in class. Maybe no matter how much you regret it, your life will not come back." Liu Tiss said sternly. Liu Tissy looks like he is only in his twenties, and at worst, Ye Xiao and others. Ye Xiao estimated that Liu Tissy had just graduated from medical university and was assigned to come here. In the past few days here, Ye Xiao heard about the situation here. "New Generation" is a special number. There are many people here, but there are only a few hundred people who really belong to the new generation. That is, the 60-1 tribe to the 90-1 tribe. The others do not belong to the new generation, but they just come here to feed the new generation.

Everyone shut up when they heard Liu Nichichi talk so seriously.

"Also, some people have opinions about me, so they can come down to argue with me alone, and don't affect everyone's learning. First aid is life. Now that it affects everyone, it is equivalent to threatening everyone's life." Liu Qiqi said shyly, and after saying that, she glared at Ma Shen.

Ma Shen had to shut up. When she heard her solemnly, Ma Shen was embarrassed to speak.

Liu Qichi walked down from the podium and took a quick turn. "People who play with their phones put them away. Yes, I am not the new generation of yours, and I am not as perverted as you new generation of people. You may think I can't deal with you, but you have to remember that I can't deal with you. I can let Uncle Liang clean up you. I believe you will like Uncle Liang very much."

Those who play with their phone immediately put away their phones.

"Who is Uncle Liang?" Ye Xiao asked quietly.

"It's the pervert who trains us to run long distances." Ma said spirit.

Ye Xiao nodded. Sure enough, the instructor that everyone feared the most was the perverted instructor who trained his long-distance running endurance and ran until he fainted.

Liu Nichi returned to the podium, "I will tell you the main symptoms of being bitten by a venomous snake: neurological venomous snake, wound pain, local swelling, sleeping, movement disorder, sagging eyes, dilated pupils, local weakness, swallowing paralysis, stuttering, drooling, nausea, vomiting, coma, difficulty breathing, and even respiratory failure. The injured person may die within 8-72 hours. Blood-circulating venomous snake, wound burning, local swelling and spreading, purple spots, spots, blisters around the wound, and slurry blood seeps out of the wound. Necrosis of skin or subcutaneous tissue, fever, nausea, vomiting, bleeding at seven orifices, blood phlegm, hematuria, blood pressure, shrinkage of pupils, cramps, and death within 6-48 hours after being bitten."

"Hiss."

Everyone took a breath, especially the horse spirit bitten by a poisonous snake. When they think about it, they are scared. If they hadn't been sent to the hospital in time, they would have probably died young, right?

"Instructor Liu, is poisonous snake really that powerful?" someone asked.

"Of course." Liu nodded shyly, "Among the number of accidental deaths in the world every year, the number of people who are bitten by poisonous snakes is second only to those who die in car accidents."

"Well, I'll tell you how to first aid after being bitten by a venomous snake." Liu Tishi said: "After being bitten by a snake, you should calm down, don't walk around, and delay the absorption of snake venom. First, you need to find a cloth strap or long shoelace to tie it 5-10 cm at the upper end of the wound (near the end of the heart). To prevent limb necrosis, relax for 2-3 minutes every twenty minutes, and repeatedly wash the snake venom on the surface of the wound with cold boiled water. Of course, there is no cold boiled water in the wild, so you can use clean water instead. Then use poison with poison.

With the teeth mark as the center, use the disinfected blade to cut the skin of the wound into a cross shape, then squeeze with both hands, pull the fire cup, vacuum straw or cover four or five layers of gauze on the wound, and suck with the gauze. There should be no wounds in the mouth. Try to suck out the venom in the wound. Take the antidote snake medicine immediately and apply the antidote poison powder around the wound. Try to minimize the action of the injured person and quickly send it to the nearby hospital for treatment. It is also best to beat the venom to the hospital and send it to the hospital to determine the type of snake venom."

"Theory should be linked to practice. If you really get bitten by a poisonous snake, you should adapt to the situation and don't follow the steps as I said." Liu said shyly.

Everyone nodded. When Liu Qishi said this, everyone became serious. The poisonous snake should not be underestimated.

Ye Xiao couldn't help but think of Mu Qingyan, the poison king in southern Yunnan. He is a master of poison! Snake venom and other things on her mobile phone may be a pediatrician?

"Well, and, it's much easier to get bitten by centipedes. Centipedes are not as venomous as snakes. The toxicity of centipedes is acidic. You can use alkaline solutions such as soapy water and sodium bicarbonate to neutralize the venom."

"If you have any questions, please ask me and I will explain it to you." Liu Chou smiled shyly.

"Well, Instructor Liu, I understand everything you said. What I want to ask is what the nemesis of the snake is?" Fatty Tian Ye asked, standing up.

"The nemesis of the snake? It should be the snake vulture. In the tropical grasslands and open forests in Africa, there is a bird with unique appearance and habits. This is the snake vulture. The birds unique to the snake vulture in Africa have a habitat all over Africa. The snake vulture always wanders in pairs or small groups on the grasslands, feeding on small animals on the ground. Its rapid and powerful pecking can cause many small animals to die on the spot. Therefore, people say that the snake vulture is a desert king with wings. Just like lions and cheetahs, the snake vulture forms a unique landscape on the African grasslands." Liu Cicchi explained.

At this time, another person stood up and asked, "Instructor Liu, I can't swim. Have you told me how to save the drowning person? When I drown in the future, everyone can save me."

This person's words immediately caused a burst of laughter.

"Hehe." Liu Qichi was also amused. "What's your name?"

"My name is Jiang Bin. It's not Leng Bingbing, but the gentle Bin." Jiang Bin said with a smile.

Ye Xiao also learned about this person during the past few days of contact. He liked to make jokes. When Uncle Qiu asked everyone what he thought, Jiang Bin deserved a beating and said that he felt a little cold.

"Okay, I'll tell you about first aid methods for drowning, so that they can know how to save you in the future." Liu Ti smiled shyly: "After lifting Jiang Bin out of the water, water, mud and dirt in his mouth and nose, wrap his fingers with gauze and pull Jiang Bin's tongue out of the outlet, unbutton the buckle and collar to keep the respiratory tract unobstructed. Then pick up Jiang Bin's waist and abdomen, so that his back is facing up, and his head droops to pour water. Or pick up Jiang Bin's legs, place his abdomen on the shoulders of the first aider, run quickly to make the accumulated water pour out. Or take a half-kneel position, place Jiang Bin's abdomen on the legs of the first aider, make his head droop, and use his hands to pour water."

"Uh." Jiang Bin touched his nose awkwardly. It turned out that Liu Cicchi directly regarded him as a drowning person.

Liu Ti said shyly: "If Jiang Bin's breathing stops, artificial respiration should be performed immediately. Generally, mouth-to-mouth blowing is the best. The first aider is located on the side of the injured, hold the wounded's jaw, pinch the wounded's nostrils, take a deep breath, and blow slowly into the wounded's mouth. When his chest is slightly raised, relax his nostrils and press his chest with one hand to help exhale. Blow repeatedly and rhythmically 16 to 20 times per minute until Jiang Bin resumes breathing."

"So this is how artificial respiration is?" Ye Xiaowan murmured in his heart: "I wonder how that girl Qianyu did when she fed her artificial respiration?"

"Instructor Liu, I don't understand. Can you demonstrate artificial respiration to show us?" Ma said mentally.

"I don't mean to find fault on purpose. I really don't understand the artificial respiration mentioned by the instructor. I want to see people practice it." Ma Shen looked at Liu Qishi's delicate face with calm eyes.

Everyone was shocked.

Want Liu Tichi to demonstrate artificial respiration in person? Isn’t this necessary for a “drowning person”? Everyone is excited. As long as Liu Tichi dares to agree, it means that the “drowning person” can have a love affair.
