Live Wilderness Adventure

Chapter 382 There is no lack of oxygen in the plateau air

My God, how long will it take to go?

In the hotel, Yao Jun collapsed on the bed, took off his shoes, and walked all day. His feet were tired and swollen, so he just wanted to sleep well now.

Put the shoes outside, why is there such a smell? Bi Fang slapped his nose, he hadn't smelled this smell for a long time, and immediately pulled Yao Jun up from the bed, asking him to put the shoes out of the window.

As for? Yao Jun got up awkwardly, and put the shoes and socks outside the house.

Bi Fang shook his head helplessly: You are not the only one here, and my nose is much more sensitive than ordinary people, so I can't stand it.

It’s all in the mountains. It’s called a hotel, but it’s actually just a few small earthen huts. Don’t even think about single rooms or anything. A room is full of earthen kangs, which can sleep at least four people.

At this time, Bi Fang and others were gathered in one room, while the guide and several others were in another room, waiting for the owner to bring dinner.

Bi Fang picked up a hot towel and washed his face, then moved the little Maza and sat around the yard with the others to warm up the fire. The temperature in the mountains fluctuated greatly. Although the weather was still hot at noon, it started to get cold at night. Even had to put on a thin cotton jacket.

When his fingers warmed up, Bi Fang said: Today is the first day for everyone to walk, and everyone's speed is different, which makes the team drag a little longer. How to adjust the appropriate pace will be our study tonight. Today, does anyone feel that they can’t keep up? Or can keep up, but feel very tired? To be honest, let me know as soon as you have a reaction. Although the altitude sickness at the 3,000-meter position may not be great, it is not impossible. And Sir, I haven't heard your words about taking a rest all day today, so don't hold on.

Attenborough laughed: You think too much, but I have always been at the forefront of the team. Whether it is mountains or rainforests, I have hiked more than far. Don't underestimate me. A while ago I was still on the road. I have hiked twelve kilometers on the grassland.

Seeing that Sir Alex had no problem, and even his face was glowing red, Bi Bian looked at Wang Yongbo and the others: What about you?

Everyone shook their heads, only Wang Yongbo scratched his head: I can't keep up with my walking today, and my heart feels weird, like being pinched by a hand. Is it a sign of altitude sickness?

Bi Fang frowned: What about you, do you have this reaction too?

Everyone shook their heads, but Jarrett and the photographer on the side raised their hands. Indeed, they didn't react just now, but now that they think about it, it seems that they have the same reaction.

These people have had medical examinations before coming, and there is no disease in their bodies.

It may be a precursor.

Wang Yongbo and the others were taken aback for a moment, and then realized that they had altitude sickness at three thousand meters? What about the next road?

It's okay. Since there is no problem in the physical examination, there is no need to worry too much. As long as you are not sick, most people will be fine for three or four kilometers, and many people are just psychological reactions. I suspect that you just exercised too much today. From 1,000 meters to 3,000 meters is directly reached by helicopter, the altitude rises a bit fast, and I haven’t fully adapted to it. Just take a good rest tonight.”

Wang Yongbo is a bit wide, but not fat enough. As for Jarrett and the photographer, Bi Fang suspects that the equipment is too heavy, because to carry the equipment, even with the help of livestock, each of them must be at least I brought nearly five catties of heavy objects with me. The high reaction is probably caused by excessive exercise.

After thinking for a while, Bi Fang came up with a plan: Well, tomorrow I will ask Rob to find two porters to help you carry your backpack. Eat more cheese and chocolate tonight. High-calorie foods are good for fighting high fever. Wait a minute. Then ask Rob to buy some water. When you set off tomorrow morning, you will drink water all the time, at least 4L of water. Take 8 bottles of Nongfu Spring or something, and drink it in small sips. Keep wanting to go to the bathroom every half an hour. That will probably be fine.”

Drink water? Wang Yongbo was taken aback, Will it work?

The audience in the live broadcast room were also very curious. Can you understand if you can find someone to recite things in front of you? Drinking water can cure high-reflexes?

[Isn't this a big water ratio? 】

[I remember that Gao Fan has medicine to take? 】

[Yes, isn’t it Rhodiola? 】

Unexpectedly, Bi Fang shook his head directly: It's useless. Those medicines really don't work. In fact, most of the anti-high medicines are placebos. They may be able to slow down the high reaction, but they have no clinical effect at all. Experiments can prove this, especially for rhodiola. So far I haven’t seen authoritative scientific proof, but the Olympic Games has listed it as a doping drug. At most, it has a certain effect on the listlessness that occurs when there is altitude sickness.”

In addition, do you think that the oxygen content in high altitudes is lower?

Bi Fang looked at the crowd and found that everyone was nodding, everyone thought so.

Isn't it? Doesn't altitude sickness appear because of the lack of oxygen in the high altitude?

Wrong. Bi Fang shook his head again. This was the second time he shook his head in a short period of time. From sea level to an altitude of 100,000 meters, the content of oxygen in the air is about 21%.

As soon as these words came out, all four were shocked.

Isn't this common knowledge?

[Is Lao Fang also high-profile (funny), and his consciousness is no longer clear. 】

Bi Fang rolled his eyes. His current maximum oxygen uptake is at least 80 or more. Such a person will experience altitude sickness when he runs to an altitude of 3,000 meters, unless he has heart disease, blood disease, cerebrovascular disease, and various other diseases. Respiratory diseases, epilepsy, schizophrenia, and uncontrolled diabetes, and many debuffs together, can be highly countered.

There is no lack of oxygen in the plateau air! It is the lack of oxygen in the plateau. Have you ever been on a plane? Its engine is essentially an internal combustion engine. If the plateau environment is 'deprived of oxygen', then the aircraft engine cannot burn fuel normally to generate power to support flight , Passengers in the cabin will also be in danger of suffocation, but in fact thousands of passengers take civil aviation planes every day to fly at an altitude of 10,000 meters is very safe. If the oxygen content in plain areas is 21%, in high altitude areas, most of the time , the proportion of oxygen is also 21%, which means that there is no lack of oxygen in the atmospheric environment. The proportion of oxygen does not change at all.”

Then how can you be so rebellious?

It's air pressure. Bi Fang didn't play charades, and gave the reason straightforwardly, At an altitude of 4270 meters, the oxygen pressure is only 58% of sea level. Therefore, although the relative proportion of oxygen in the atmosphere has not changed, due to the air Thin, the absolute amount of oxygen becomes smaller, which leads to hypoxia.

When our human body goes to the plateau, the demand for oxygen is the same as that of the plain. The lower absolute oxygen content of the plateau means that we need to breathe more air to obtain oxygen. Our breathing and heartbeat must speed up. The plain The amount of oxygen you can get with one breath, you have to breathe twice on the plateau.

The effect of increasing the maximum oxygen uptake is second, and the utilization rate of oxygen is higher. Others need to take multiple breaths to maintain oxygen intake on the plateau, but Bi Fang is still enough for one time. The only difference is probably the expansion of the chest cavity. will be bigger.

Breathing is easy to consume water. I told everyone in the desert that it is best to breathe through the nose instead of the mouth, so that the water loss will be less. Because the breathing frequency and amplitude are greater, we will lose a lot of water, so we will lose more water than Plain areas are more water-scarce, and at the same time, due to the increase in lung activity and heart activity, a large amount of water will be consumed, and water shortage will easily lead to a decrease in blood flow and a decrease in the amount of oxygen transported in the body. If water is not replenished in time, the consequences will be very serious.”

The reason for the high is cold and hypoxia, which will make people's brains dull. When they react to the lack of oxygen, the consequences are already very serious. This is the so-called high reaction.

That's why drinking water can effectively alleviate the high reaction. This thing is better than medicine.

[Awesome, scratching your ass with a knife is an eye-opener! 】

[Heifer stands on his head, so awesome]

【Who did you learn all the fucking allegory from? 】

Just as everyone opened their eyes, the door suddenly opened, and a black-faced Sherpa came in with several large plates.

Finally able to eat!

Yao Jun jumped up from the bed and couldn't wait to come to the table. He walked all day today and was almost starved to death.

Eat more. We are now in Faktin at an altitude of 2,610 meters, which is the middle point between Lukla and Nanchi. There is still a long way to go tomorrow, so we must eat enough.

Bi Fang picked up the chopsticks and handed them to everyone. The food on the table was not unusual. They were fried noodles, fried rice, noodle soup, steamed buns, etc., plus rupai and pizza.

In the past, most of the people who took the EBC line were white people from Europe and Ugly. In recent years, the number of people from China has gradually increased. There are a lot of Chinese food in the inns and hotels along the line, such as dumplings and noodles, and there are more chopsticks. It’s a good time, otherwise we can only eat Western food now, or the kind that is grasped by hand.”

Because of hunger, everyone didn't care too much about the image, so they picked up chopsticks, knives and forks and started eating.

Yao Jun on the side stopped the boss: Boss, I think you have a WiFi signal here, can you tell me the password?

The boss wiped his hands and smiled. His weather-beaten face was covered with wrinkles and he was very simple and honest. Unfortunately, what he said was not simple and honest. He stretched out three fingers: 300 rupees.

Yao Jun was stunned: Damn it? Does it cost money? Please tell me the password, I'm out! Let everyone use WiFi!

Unexpectedly, the boss shook his head again: Three hundred per person, let me enter the password?

Yao Jun: .

Hahaha, forget it Yao Jun. Bi Fang patted him on the shoulder, It's not necessary, don't expect the Wifi speed to be so good in a place where the electricity is not even stable. Be honest and use the data.

After everyone had dinner, Bi Fang summarized the problems and points to pay attention to.

Whether a person is hypoxic can't be based on feeling, because the brain and heart are very tolerant, and it is not easy to feel it, it has to be measured. Observing the color of the lips is a measurement, and it is a visual inspection. The color of the lips represents the color of arterial blood. Purple, black means Arterial blood is not saturated with oxygen, and the body is hypoxic. Pay attention when you climb Mount Everest. If there is no problem, the most convenient way is to use a blood oxygen saturation meter, which can detect the truth in 10 seconds. I think there is one in Rob , I’ll take you guys to ask for one tomorrow.”

The rest is the problem of hiking. I will call you in the morning. Go to bed early tonight. I will start at 7:30 tomorrow from 2610 meters in Faktin to 3440 meters in Namchi Bazaar. I will climb 800 meters and teach you at that time Some mountaineering essentials.”

In the evening, Bi Fang turned off the live broadcast, went out to exercise for a while, and then went back to his room to rest.

At 6:00 in the morning, Bi Fang opened his eyes. This was the first time he slept in bed during a live broadcast. He was not used to it, but he got up from the bed quickly, put on his clothes, opened the door, and opened the live broadcast.

The drone takes off immediately.

【So early? It's only half past six, isn't it? 】

[Is it still daylight? 】

It's because of the longitude. In spring and summer, it usually doesn't dawn until seven o'clock on Mt. Everest. Bi Fang exhaled a mouthful of cold mist, showing that the temperature was still very low in the morning, and frost could be clearly seen on the leaves beside him.

Today is April 21st. I expect to reach the base camp of Mount Everest in six days, and then I will have less than a month to practice. It depends on the weather forecast of the Meteorological Bureau. If the time comes early, it may It’s not even half a month, so I have to increase the intensity of my training, so I got up early in the morning.”

Half an hour later, Bi Fang, who was sweating profusely, returned to the house, boiled some water, and mixed some cold water, then went to the yard, took off his clothes, let the drone avoid the viewing angle, and poured hot water on his head .

Phew! It's much more comfortable. Bi Fang shook the towel and wiped his face. After exercising, the blood vessels expanded, and he was not afraid of the severe cold, let alone not considered severe cold, still above zero.

【I'll wipe it, isn't it cold? 】

[Please fly the drone to the right, I can only see one head. 】

【Too fierce, is this a real man? Shower outside. 】

The sound of water outside the house quickly attracted everyone's attention. At this time, it was also daylight. Yao Jun blinked, yawned and got up, and then saw Bi Fang, who was covered in mist, coming in from outside the house.

Yao Jun rubbed his eyes vigorously, and said in shock: Fuck, are you going to spontaneously combust? Why are you smoking all over?

Take a shower, get up quickly, and this, you all use it. Bi Fang put on his clothes and threw out a small bottle casually.

What's this?

Everyone came over and found that it was an alcohol spray.

Alcohol spray, wait a minute to wash your feet, and then spray this on, especially on the toes and heels. After drying, apply a little alcohol to increase the tolerance of the feet and make them less tired. I don't tell him.

Yao Jun didn't understand, but he was greatly shocked. This was the first time he knew such a thing: What's the reason?

It's pain relief, and it will have a chemical reaction with the leather, making the shoes soft. The hiking shoes are usually new, and we wear them too. The friction of new shoes is the greatest, but they are easy to rub your feet if you haven't used them. You can apply some alcohol. It will be soft.

Yao Jun was excited after hearing this, and immediately went under the bed to start the experiment.

Speaking of which, you didn't say it earlier? I worked hard yesterday!

Forgot, I didn't think about it when I came out of the hotel that day, and I left after that, so there is no need to bother.

Grass!

(Look at the real copy, my lord. It's only a few bucks a book.)

The giant-toothed ant (scientific name Odontomachus bauri) takes only 1/3000th of a second to bite, which is the fastest action among animals.
