Chapter 382 There is no lack of oxygen in the plateau air
"Oh my God, how long do we have to go?"
In the hotel, Yao Jun collapsed on the bed, took off his shoes, and after walking all day, his feet were tired and swollen, so now he just wanted to have a good sleep.
"Put the shoes outside, why do they smell so bad?" Bifang fanned his nose. He hadn't smelled this smell for a long time. He immediately pulled Yao Jun up from the bed and asked him to put the shoes outside the window.
"As for that?" Yao Jun stood up awkwardly and placed his 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."
They are all in the mountains. They say they are hotels, but they are actually just a few small mud houses. Don't even think about single cubicles. Each room is equipped with a mud kang, which can sleep at least four people.
At this time, Bi Fang and others were gathered in one room. The guide and several other people 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 small matza and everyone sat around the yard to warm up. The temperature in the mountains fluctuated greatly. Although it was still a little hot at noon, it started to become cold at night.
He even had to put on a thin cotton-padded jacket.
When his fingers warmed up, Bi Fang said: "Today is the first day for everyone to walk. Everyone's speed is different, which makes the queue a bit long. How to adjust the appropriate pace will be what we will study tonight.
Do you think you can't keep up with the topic today? Or you can keep up, but feel very tired? To be honest, tell me as soon as possible if you have any reaction. Although altitude sickness at 3,000 meters is unlikely, it is not impossible.
And sir, I haven’t heard you say you want to rest all day today, so don’t insist on it.”
Attenborough laughed: "You are thinking too much. I have always been at the front of the team. Whether it is mountains or rainforests, I have hiked more than a few miles. Don't underestimate me. A while ago I was still on foot."
I’ve hiked twelve kilometers on the grassland.”
Seeing that Sir Alex had no problem and his face was even glowing red, Bi Fang looked at Wang Yongbo and others: "Where are 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 this a precursor to altitude sickness?"
Bi Fang frowned: "What about you, do you also have this reaction?"
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, they seem to have the same reaction themselves.
These people all had physical examinations before coming here, and they were free of any diseases.
"Maybe it's a sign."
Wang Yongbo and others were stunned for a moment, and then they realized that they actually suffered from altitude sickness at three thousand meters. What about the rest of the way?
"It's okay. Since there is nothing wrong with the physical examination, there is no need to worry too much. As long as you are not sick, most people will have no problems with three or four kilometers. And many people are just psychological reactions. I suspect you just exercised a little too much today. In addition,
It is a direct helicopter ride from 1,000 meters to 3,000 meters. The altitude rises a bit quickly and I haven’t fully adapted yet. I just need to have a good rest tonight.”
Wang Yongbo is a bit wide, but not to the point of being fat. As for Jarrett and the photographer, Bi Fang suspects that the equipment is just too heavy. Because they have to carry the equipment, even if there are animals to help, the two of them are at least
I carried nearly five kilograms of extra weight, and my high reflexes were probably caused by excessive exercise.
After thinking for a while, Bifang came up with a plan: "In this way, tomorrow I will ask Rob to find two porters to help you carry your backpack. You guys eat more cheese and chocolate tonight. High-calorie food is good for fighting high blood pressure. Wait a minute.
Let Rob buy some water. We will set off early tomorrow morning. You will drink water all the time, at least 4L of water. Get 8 bottles of Nongfu Spring or something. Drink it in small sips, and keep going to the toilet as often as every half hour.
That’ll probably be fine.”
"Drink water?" Wang Yongbo was stunned, "Does it work?"
The audience in the live broadcast room was also very curious. Is it still understandable that I asked someone to carry things in front of me? Drinking water can cure high reflexes?
【Isn’t this a great comparison? 】
[I remember, isn’t there any medicine that can be taken for high reflexes? 】
[Yes, isn’t it Rhodiola rosea? 】
Unexpectedly, Bi Fang shook his head directly: "It's useless. Those medicines are really not as effective as drinking water. In fact, most of the anti-high medicines are placebos. They may be able to slow down high symptoms, but they have no clinical effect at all."
Tests can prove it, and this is especially true for Rhodiola rosea. I have not seen any authoritative scientific evidence so far, but the Olympic Games has listed it as a doping drug. At most, it has a certain effect on the malaise that occurs when you have altitude sickness."
"Also, do you think the oxygen content is lower at high altitudes?"
Bi Fang looked at everyone and found that everyone was nodding. Everyone thought so.
"Isn't it? Doesn't altitude sickness occur because of the thin oxygen in high altitudes?"
"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 oxygen content in the air is about 21%."
As soon as these words came out, everyone was shocked.
Isn't this common knowledge?
[Is Lao Fang also having high reflexes (funny), his consciousness is no longer clear. 】
Bi Fang rolled his eyes. His current maximum oxygen uptake was at least over 80. A person like this would suffer from altitude sickness when running to an altitude of 3,000 meters, unless he had heart disease, blood disease, cerebrovascular disease, etc.
Respiratory diseases, epilepsy, schizophrenia and uncontrolled diabetes, all with the combination of many debuffs, can lead to high reactions.
"There is no lack of oxygen in the plateau air! It is the lack of oxygen in the plateau. Have you ever flown on an airplane? Its engine is essentially an internal combustion engine. If the plateau environment is 'oxygen-deficient', 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. In fact, thousands of passengers take civil aviation aircraft to fly at an altitude of 10,000 meters every day. 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 come you have high reflexes?"
"It's the air pressure." Bi Fang didn't play riddles and gave the reason straightforwardly, "At an altitude of 4,270 meters, the oxygen pressure is only 58% of that at sea level. Therefore, although the relative proportion of oxygen in the atmosphere has not changed, due to the air
Being rarefied, the absolute amount of oxygen becomes smaller, resulting in hypoxia."
"When our body goes to a plateau, its demand for oxygen is the same as that on the plains. The lower absolute oxygen amount on the plateau means that we need to breathe more air to obtain oxygen, and our breathing and heartbeat must speed up. On the plains,
The amount of oxygen you can get with one breath would take two breaths on the plateau."
The effect of increasing the maximum oxygen uptake lies in the second, and the utilization rate of oxygen is higher. Others need to take multiple breaths to maintain oxygen intake on the plateau, but Bifang still takes one breath. The only difference is probably the expansion of the chest cavity.
It will be bigger.
"Breathing can easily consume water. I told everyone in the desert that it is best to breathe through the nose instead of the mouth, so that less water is lost. Because the breathing frequency and amplitude are greater, we will lose a lot of water, making us
Plain areas are more dehydrated. At the same time, due to the increase in lung activity and heart activity, a large amount of water is consumed. Lack of water can easily lead to a decrease in blood flow and a decrease in the amount of oxygen transported within the body. If water is not replenished in time, the consequences will be serious."
The cause of hyperactivity is cold and lack of oxygen, which can slow down a person's brain. By the time he or she realizes that he or she is deprived of oxygen, the consequences will be very serious. This is the so-called hypersensitivity reaction.
"So drinking water can effectively relieve high reflexes. This thing is better than medicine."
[Awesome, scratching your butt with a knife, it’s an eye-opener!]
[The heifer stands on its head, so awesome that it reaches the sky]
[Who the hell did you learn your idioms from?]
Just as everyone was opening their eyes, the door suddenly opened, and a dark-faced Sherpa man came in carrying several large plates.
“Finally I can eat!”
Yao Jun jumped up from the bed and couldn't wait to come to the table. He had been walking all day and was almost starving to death.
"Eat more. We are now at Faktin, 2,610 meters above sea level, which is the midway point from Lukla to Nanchi. We still have a long way to go tomorrow, so we need to eat enough."
Bi Fang picked up his chopsticks and handed them to everyone. The food on the table was not unusual. They were all fried noodles, fried rice, noodle soup, steamed buns, etc., plus spaghetti and pizza.
"In the past, most of the people who took the EBC route were white people from Europe and Chou. In recent years, the number of people from China has gradually increased. The inns and hotels along the route have a lot more Chinese food, such as dumplings and noodles, and they also have more chopsticks, which is a great way to catch up.
It’s a good time, otherwise we can only eat Western food now, and it’s still the kind you eat with your hands.”
Because they were hungry, everyone didn't care much about their 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 honest. Unfortunately, what he said was not honest. He stretched out three fingers: "300 rupees."
Yao Jun was shocked: "What the hell? Does this cost money? Okay, okay, tell me the password, I'm out! Let everyone use WiFi!"
Unexpectedly, the boss shook his head again: "Three hundred per person, shall I enter the password?"
Yao Jun: "."
"Hahaha, forget it Yao Jun." Bi Fang patted him on the shoulder, "No need, don't expect the Wifi speed to be very good in a place where even the power is unstable. Just use the traffic."
After everyone finished dinner, Bi Fang summarized the problems and points of attention.
"Whether a person is hypoxic cannot be based on feeling, because the brain and heart are very tolerant and cannot be felt easily. It must be measured. Observing the color of lips is a measurement, a visual inspection. The color of lips represents the color of arterial blood. Purple and black indicate
The arterial blood is not saturated with oxygen, and the body is hypoxic. You should pay attention when climbing Mount Everest to avoid any problems. The most convenient thing is to use a blood oxygen saturation meter, which can detect the true situation in 10 seconds. I think Rob has some
, I’ll take you to get one tomorrow.”
"The rest is about hiking. I will call you in the morning. Go to bed early tonight. We will set off at 7:30 tomorrow from 2610 meters in Fakting to 3440 meters in Namchi Bazaar. It will climb 800 meters. I will teach you then.
Some tips for mountain climbing.”
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 six o'clock in the morning, Bi Fang opened his eyes. This was the first time he slept on a bed during a live broadcast. He was not used to it, but he quickly got up from the bed, put on his clothes, opened the door, and turned on the live broadcast.
The drone took off immediately.
【So early? It's only half past six, right?】
【It’s still daylight, isn’t it?】
"Because of the longitude, it usually doesn't get bright until seven o'clock on Mount Everest in spring and summer." Bi Fang exhaled a breath of cold mist. It can be seen that the temperature in the morning is still very low, and frost can be clearly seen on the leaves on the side.
"Today is April 21st. I expect to reach the Everest base camp in six days. Then I will have less than a month to train. It depends on the weather forecast from the Meteorological Bureau. If the opportunity occurs early, I may
It didn’t even last half a month, so I had to increase the intensity of training, so I got up early in the morning.”
Half an hour later, Bifang, who was sweating profusely, returned to the house, boiled some water, and mixed some cold water. Then he went to the yard, took off his clothes, let the drone avoid the view, and poured the hot water on his head.
.
"Phew! I feel much more comfortable." Bi Fang shook the towel and wiped his face. After exercising, his blood vessels expanded. He was not afraid of the severe cold at all, not to mention it was not considered severe cold, it was still above freezing.
【I wipe it, won’t it be cold?】
[Please, if the drone flies to the right, I can only see one head.]
[Too fierce, is this a real man? Take an outdoor shower.]
The sound of water outside the house quickly attracted everyone's attention. It was also dawning at this time. Yao Jun blinked, yawned and stood up. Then he saw Bifang walking in from outside the house, covered in mist.
Yao Jun rubbed his eyes vigorously and said in shock: "Damn it, are you about to spontaneously combust? Why are you covered in smoke?"
"You took a shower, get up quickly, and here is this, you all can use it." Bifang put on his clothes and threw out a small bottle.
"What's this?"
Everyone came over and found that it was an alcohol spray.
"Alcohol spray, wait a minute, wash your feet, and then spray this on, especially 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 like it for most people.
tell him."
Yao Jun didn't understand, but he was shocked. This was the first time he knew that such a thing existed: "What's the reason for this?"
"It relieves pain, and it will react chemically with the leather to make the shoes softer. Hiking shoes are usually new, and the ones we wear are the same. New shoes have the greatest friction, but if you are not used to it, it will easily rub your feet. You can apply some alcohol on it.
It’s soft.”
After hearing this, Yao Jun looked excited and immediately went under the bed and started experimenting.
"Why didn't you tell me earlier? I worked hard yesterday!"
"I forgot. I didn't think about it when I came out of the hotel that day. I left after that, so there's no need to bother."
"Grass!"
