In the confined space, the sound of breathing kept rising and falling, low and thick, like a broken bellows.
In the darkness, Bifang and Attenborough huddled up to rest, slowing down the consumption of physical energy and heat. Only Tenzin continued to dig along the rope, his hands almost numb from the cold.
It's not that Bi Fang is being hypocritical. Even when the life and death of his team members are at stake, he still has to complete the mission without oxygen. The reason is that almost his whole body is in pain. Being able to dig out Tenzin has squeezed out the last bit of his strength.
If you choose to inhale oxygen at this time, you will not be able to complete the mission or save people.
He truly deserves to be the warrior of the third pole and the darling of the mountains.
Feeling the figure shaking in the darkness, Bi Fang couldn't help but think.
The joking saying that Sherpas have a third lobe of lung specifically used for mountaineering is not groundless. It is genetically determined that they can adapt to the high mountain environment better than ordinary people; their blood pressure is very low, ensuring sufficient blood supply to the brain.
, the muscles are powerful in stretching; compared with the legs, their trunks are longer to ensure a stable center of gravity in rugged mountains.
"Mr. Bi, Mr. Attenborough?"
"exist."
My head is getting dizzy.
There is so little oxygen in the air that every breath is ineffective. No matter how hard the alveoli try to expand, they can never filter oxygen. The blood flow becomes slower and slower, and the hemoglobin tries its best to capture oxygen molecules, but it is always in vain.
The silent darkness made people panic. At this moment, Bi Fang could no longer suppress his panic. This was not fear, but a physiological behavior caused by lack of oxygen, which was difficult to overcome simply with mental strength.
It would be nice if there was light.
The moment they were hit by the wind and snow, apart from the backpacks fixed on their backs, he, Sir, and Tenzin's headlamps had already been washed away, and they didn't know where they landed. If there had been a lamp at this time, they wouldn't be like now.
His lungs rose and fell, and Bifang took a deep breath again. The oxygen in the air was further squeezed out, and in contrast, the concentration of carbon dioxide increased.
After regaining his composure, Bi Fang made a preliminary diagnosis for himself. His arm was completely out of strength, and his muscles were spasming, stiff, or slightly strained. A strain would be troublesome and would not be easy to heal in a short time. He hoped it was just a simple out of strength.
.
If you don't go out, carbon dioxide poisoning may kill you.
Not only carbon monoxide can cause poisoning, carbon dioxide can also cause poisoning.
Under normal circumstances, the carbon dioxide content in the air exhaled by the human body is 4.2%. The partial pressure of carbon dioxide in the blood is higher than the partial pressure of carbon dioxide in the alveoli. Thanks to this, carbon dioxide can diffuse in the alveoli.
However, once the concentration of carbon dioxide in the environment increases, the concentration in the alveoli will also rise. At this time, the pH will change drastically, which will stimulate the respiratory center, eventually leading to paralysis of the respiratory center, causing the body to suffer from hypoxia and suffocation.
"Damn it, why did we encounter an avalanche?"
Bi Fang raised his head and smashed it against the snow wall, unable to understand why.
Perhaps feeling the change in the atmosphere, Tenzin called out in a low voice: "Mr. Bi, Mr. Attenborough, are you okay?"
This is already the thirteenth question Tenzin has asked, and he will ask it again almost every half minute. Just when Bi Fang wants to answer the same as before, an indescribable sense of comfort appears in his body, and every time
Every cell is jumping for joy, as if
Oxygen concentration increased!
Bi Fang sat up suddenly and expanded his lungs again. Yes, yes, the oxygen concentration in the air has increased! It's not an illusion!
Are you going to dig it out?
No, Tenzin dug along the rope. Was anyone not buried?
impossible?
With doubts in his heart, Bi Fang followed the rope to Tenzin's side: "Tenzin, keep digging, hurry up, keep digging!"
Tenzin looked confused, but he continued to dig without stopping, and large chunks of snow were thrown out.
While digging, Bifang was keenly aware that the oxygen concentration in the air seemed to have increased.
"What's wrong, Mr. Bi?"
Tenzin was puzzled, and for some reason Bi Fang suddenly reacted.
Bi Fang didn't answer. He supported the snow in front of him with both hands and pushed hard with both hands.
Suddenly, the snow layer in front of everyone suddenly collapsed, a large amount of snow dust splashed, the air circulation stirred up a breeze, and fresh air rushed in.
Digging through!?
Tenzin and the semi-conscious Attenborough widened their eyes. Although they could not see anything in the darkness, they were keenly aware of the air circulation.
Out!?
No, there isn't.
Bi Fang looked around at the darkness in front of him. The sky on Mount Everest was very clear. If he went out, it would never be as dark as it is now and he would not be able to do anything.
This is an internal "vacuum".
Bi Fang recalled the scene when the avalanche occurred and gradually simulated the scene at that time.
Taking a breath to relieve the dizziness caused by lack of oxygen, Bi Fang explained: "When the avalanche happened, it quickly submerged everything, but the shape of the Eagle Head Ice Slope was so unique that after the torrent washed away, it left some space in the rocks.
"
Just like a plane crashing into the sea and being quickly enveloped by the sea, the air in the cabin will be squeezed to the top of the cabin and cannot flow out, forming a breathable area.
The eagle head of the ice wave rises into the sky, but its back is facing the direction of the avalanche, and the torrent rushes down. It is really like an eagle protecting the last living space under the avalanche!
Just as Attenborough and Bi Fang were feeling incredible, Tenzin's shout rang out in the darkness.
"Mr. Bi, there are other people here! Lama Qin! Lama Qin! It's the mountain god showing up! It's the mountain god showing up! Lama Qin! Lama Qin!"
Anyone?
Bi Fangqiang stood up, and suddenly, a dazzling light came on.
Bi Fang quickly covered his eyes.
Tenzin, who picked up the headlamp, also realized what he was doing was wrong and quickly turned off the light.
After finally adapting to the dazzling headlights, Bifang slowly opened his eyes. In a small space, Yao Jun, Rob, and Jarrett were all here!
"Everyone is okay, everyone is okay!"
Tenzin was obviously a little excited, but the next moment, his mood was much lower, "It's a pity that Uncle Holt and Uncle Leza, they shouldn't have escaped. I don't know what's going on now."
Attenborough comforted the young man: "It's all instinctive reaction. There is no right or wrong. Don't pay too much attention to it. The mountain god will bless them."
Bi Fang coughed twice, came to Yao Jun and others, and checked them one by one.
They were all still breathing, and their breathing was normal, but they fell into a coma briefly.
Bifang took out oxygen bottles from their backpacks and gave them to them. Bifang rummaged through Rob's backpack and successfully found a small radio.
call.
Bi Fang breathed a sigh of relief when he found this thing.
Fortunately, it's still there. With this thing, even if they can't dig it out, they can rest assured and wait for rescue.
There is still one chapter left to finish, so I’ll take a look at it later.
