Wilderness Challenge for Live Broadcast

It was not the first time Liu Yan and Sun Yue had rescued an emergency, so they naturally knew the severe lack of oxygen in the mountains.

That feeling is like holding a balloon, blowing air into it, and then breathing it in with your mouth, and then blowing it in again, and so on. After dozens of seconds, because the oxygen content is getting lower and lower, you will feel dizzy and very uncomfortable. !

Okay, now we have limited manpower. If we want to find the affected people in a short time, we can only be divided into three groups. With this point as the center, the three of us form a fan shape, divided into three directions, radiate outward, and conduct a carpet search.

Once there is any situation, use the satellite walkie-talkie to call immediately. After the other two hear the signal, they must first write down the current search coordinates, and then rush to the call point immediately. Remember, it is immediately!

Time is tight, Chen Xu can only use the simplest method.

remember!

Liu Yan and Sun Yue answered almost in unison.

Next, the three of them took out their snowshoes from their backpacks and buckled them on the soles of their shoes. Then, with their backs facing each other, they held portable life detectors and carefully searched in the direction they decided.

The life detectors they used were somewhat similar to the metal detectors used by Chen Xu during the live broadcast on Dakai Mada Island, but this is a very advanced radar detector, which can emit electromagnetic waves through the body to penetrate the snow layer. Radiates deep.

When it senses the breathing, body movement and other vital signs of the buried life, it will immediately feed back on the screen, and can roughly measure the distance and depth of the buried life, and it will not be affected by the ambient temperature, hot objects and sound interference. Influence.

It's a pity that the sound waves emitted by the portable radar life detection gas have a limited bandwidth and cannot carry out a large-scale search, so they can only walk out one by one with three people.

Everyone must remember that if one day, you also take a helicopter and quickly enter such a high-altitude area from a low altitude, the first thing to do is to try to slow down everything.

You know, in a hypoxic state, if the body wants to maintain normal life activities, the heart must work harder to transport oxygen to various parts. This is called climate adaptation.

Scientists have done pre-experimental tests. If a person has not experienced plateau adaptation and is suddenly thrown to the top of Mount Everest, it will take only 5 minutes for him to die immediately.

As soon as Chen Xu finished these few words, the audience couldn't help but joked:

666, didn't he freeze to death?

Scientists have also done,

Blindfold a person, cut his wrist with a fake knife, and put the sound of bleeding next to him, and a hundred years later, he will be scared to death!

Scientist: I haven't done these experiments.

2333333, you are real skins!

Looking at these teardown bullet screens, Chen Xu couldn't help but continue to explain:

So, survival and self-rescue in high-altitude snow-capped mountains is very similar to mountaineering. The most important thing is to control your breathing and physical strength, that is, keep your breathing evenly at all times, so as to save the consumption of oxygen cylinders.

And one of the most effective ways to save energy is snowshoes. The size of snowshoes is like a small snowshoe. It can effectively distribute the weight of the human body over a larger area and prevent the feet from completely sinking into the snow.

In this way, you will save the action of stepping into the snowdrift and pulling it out again. You can't see it once or twice, but if you walk for an hour, you will save more than half of your energy. And saving energy means saving oxygen!

Of course, if you don't have snowshoes in the wild, you can also use ropes and cloth strips to tie the branches into a plane, and finally fix them on the shoes.

During the search and rescue process, Chen Xu kept telling the audience some important skills related to self-rescue and survival in the snow-capped mountains while staring at the equipment.

Another important point is the eyes. At an altitude of 7,500 meters, it is already considered as the closest position on the earth to the sun. The sunlight at this height is directly shining down, and the ultraviolet radiation is extremely strong, so you must not stare at it for a long time. sun.

Besides, because the snow surface is exposed to the sun, the snowflakes on the surface will melt into small ice crystals, reflecting the light. If you stare at the snow surface for a long time, you will easily suffer from snow blindness. The best way is to wear goggles.

If you don't have one, you can use cloth strips instead. At the position of the eyes, use a sharp tool to cut a gap. Because the gap is small, the things that the eyes can see and the light source they receive are small, thus avoiding snow blindness. occur.

Just when Chen Xu had just finished speaking these few words.

Suddenly, there was a beep from the satellite intercom on the chest:

Report to Team Chen! The situation of the friends in the southeast direction!

It's Liu Yan's position!

Stand by, we'll be there right away!

After Chen Xu finished answering, he immediately inserted the trekking pole in his backpack in front of him as a mark.

Then, he quickly turned his head and rushed towards Liu Yan.

A minute later, the three of them gathered at the spot where Liu Yan discovered the anomaly.

I saw that on the screen of the radar life detector, there was a red dot about two meters deep under the snow!

The heartbeat is weak, but there are indeed signs of life! Hurry up, get ready to dig!

After Chen Xu confirmed the signal, he quickly took out a portable snow shovel from his backpack, which looked like a foldable military shovel.

Therefore, Liu Yan and Sun Yue followed suit.

The depth of two meters is not much. It took about two minutes for the three of them to dig to a depth of 1.56 meters.

Stop! Use your hands instead, don't hurt the victim!

Seeing that he was about to reach the signal position, Chen Xu immediately ordered to stop.

Then, like a dog planing, the three of them planed the snow pit with their hands.

After dozens of seconds, Chen Xu suddenly felt that his gloves seemed to have dug up something!

Yes! Yes!

He shouted twice in surprise.

Sure enough, under the camera, the audience saw a touch of pink, which should be a protective jacket!

It seems to be an arm! Quick, dig out the head first!

The protection of the brain and allowing him to breathe as quickly as possible are the most important. Of course, Chen Xu must find a way to dig out his head first.

After a while, the three dug out a victim in pink protective clothing from the snowdrift.

It's a woman!

However, upon closer inspection by the audience, the victim's chest didn't seem to rise and fall.

In other words, she was not breathing!

Is the person already dead?

Immediately, many people felt a little lost in their hearts. Seeing Master Xu go all out to dig her out, they didn't expect this to be the result.

But Chen Xu did not give up.

He took off the gloves directly, and under everyone's suspicious eyes, he pulled open the neckline of the female victim, and put his hand in!
