Liu Yan and Sun Yue are not the first time to rescue the people, so they naturally know that the lack of oxygen in the mountains is terrible.

That feeling is like holding a balloon, blowing into it, and then exhaling it in with your mouth, blowing it in again, and so on, and after dozens of seconds, because the oxygen content is getting lower and lower, you will be 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 divide into three groups, with this point as the center, the three of us are fan-shaped, divided into three directions, radiating outward, carpet search. ”

"As soon as there is any situation, immediately use the satellite walkie-talkie to call, and the other two people must first note the current search coordinate location after hearing the signal, and then immediately rush to the call point, remember, it is immediately!"

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

"Remember!"

Liu Yan and Sun Yue replied almost in unison.

Next, the three of them took out their snowshoes from their backpacks and buckled them on the soles, and then turned their backs to their backs, holding portable life detectors, and carefully searched in the direction they decided.

The life detector they used in their hands was somewhat similar to the metal detector used by Chen Xu during the live broadcast on Dakaimada Island before, except that this is a very advanced radar-type detector, which can emit electromagnetic waves through the body, penetrate the snow layer, and radiate to the depths.

When it senses the breathing, body movement and other life characteristics of the buried life, it will immediately feedback to the screen, and can roughly measure the distance and depth of the buried life, and is not affected by the ambient temperature, hot objects and sound interference.

Unfortunately, the portable radar life detection gas has a limited bandwidth of sound waves, and it cannot be searched in a large area, so it can only rely on three people to walk out one footprint at a time.

"Remember, if one day, you also take a helicopter and quickly enter such a high altitude from a low altitude, the first thing you will do is to slow everything down as much as possible."

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

"Scientists once predicted that if a person was suddenly thrown to the top of Mount Everest without getting used to the altitude weather, it would only take five minutes for him to die instantly. ”

As soon as Chen Xu finished saying these words on the front foot, on the back foot, the audience couldn't help but joke:

"666, wasn't he frozen to death?"

"Scientists have also done it, blindfolded a man, cut his wrist with a fake knife, and put a bleeding sound next to it, and a hundred years later, he will be scared to death!"

"Scientist: I haven't done any of these experiments. ”

"2333333, you're real skin!"

Looking at these barrages of "demolition", Chen Xu couldn't help laughing, but he continued to explain:

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

"One of the most effective ways to save energy is the snowshoe, which is the size of a small snowboard, which can effectively spread the weight of the human body over a larger area and avoid the foot getting completely stuck in the snow. ”

"In this way, you will save the action of stepping into the snowdrift and pulling it out again, which you can't see once or twice, but walking for an hour, you will save more than half of your physical strength. And to save physical strength is to save oxygen!"

"Of course, if you don't have snowshoes in the wild, you can also use ropes and strips of cloth to tie tree branches into a flat surface and finally fix them to your shoes. ”

During the search and rescue process, Chen Xu stared at the instrument while constantly telling the audience some important skills related to self-rescue and survival in the snow mountain.

"Another important point is that the eyes, 7,500 meters above sea level, is already the closest position to the sun on the earth, this height of sunlight, direct down, ultraviolet radiation is very large, so you must not stare at the sun for a long time. ”

"Moreover, because the snow surface is irradiated by the sun, the surface snowflakes will melt into Xiaoice crystals, reflecting light, staring at the snow surface for a long time, it is easy to suffer from snow blindness, the best way is to wear goggles." ”

"If not, you can use a strip of cloth instead, and use a sharp weapon to cut a gap in the position of each eye, because the gap is small, so the eye can see what and receive the light source is smaller, and then the occurrence of snow blindness is avoided. ”

Just when Chen Xu just finished saying these words.

Suddenly, the satellite walkie-talkie on the chest immediately came with a "dripping" sound:

"Report to Team Chen!

It's Liu Yan's location!

"Stand by and we'll be there!"

After Chen Xu finished answering, he immediately stuck the trekking poles in his backpack in front of him as a marker.

Then, he hurriedly turned around and rushed towards Liu Yan.

A minute later, the three of them gathered at the location where Liu Yan found the anomaly.

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

"My heart is beating weakly, but there are still signs of life!

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

So, Liu Yan and Sun Yue also took action.

The depth of two meters is not much, and it took the three of them about two minutes to dig to the position of one meter five or six.

"Stop, use your hands instead, don't hurt the victims!"

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

Then, like dogs, the three of them dug the snow pit with their hands.

It wasn't until dozens of seconds later that Chen Xu suddenly felt that his gloves seemed to have dug up something!

"There is!

He shouted twice in surprise.

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

"Looks like an arm! Quick, dig your head out first!"

The protection of the brain, as well as letting him breathe as soon as possible, is the most important thing, of course Chen Xu has to find a way to dig out his head first.

In a few moments, the trio dug out a victim in a pink hazmat suit from the snowdrift.

It's a woman!

However, under the closer look of the audience, the chest of this female victim did not seem to rise and fall.

That is, she is not breathing!

Is man dead?

Suddenly, many people felt a little lost in their hearts at once, watching Xu Ye dig her out with all his might, but he didn't expect this to be the result.

But Chen Xu did not give up.

He took off his gloves directly, and under everyone's puzzled gaze, he pulled open the neckline of the female victim and put his hand directly into it!
