On-scene emergency response is a highly specialized task; sometimes, the management on site is more important than the emergency measures!

At the emergency scene, the first step is to conduct an injury assessment and classification of the wounded, which is essential during large-scale disasters.

Because then, the number of injured is large, the injuries are complex, and doctors and emergency resources are relatively limited. It's not about whose injuries are the most severe; there's an efficiency issue, and sometimes the choice is particularly cruel.

For example, a critically injured person requires a medical team three hours of surgery to survive!

And this medical team can also save six relatively seriously wounded individuals during this time. In such cases, how should one choose?

This requires the on-scene medical director to make decisions based on the classification of injuries.

The classification of the injured is generally divided into four categories by color.

First category, red, severe injuries requiring immediate treatment;

Second category, yellow, relatively serious injuries that can be delayed for treatment;

Third category, green, minor injuries, the injured can move on their own;

Fourth category, black, deceased, or those with fatal injuries where there is no hope of treatment.

Lin Jie rushed to the scene. At this moment, the roaring sound in his ears had subsided a lot. He heard the cries of the wounded, the shouts of bystanders, and the continuous alarms of cars and electric vehicles.

He glanced around and found seven people lying on the ground in front of him. Two were unconscious, one was convulsing involuntarily, and four were continuously wailing.

Lin Jie judged by common sense that the person convulsing might have the most severe injury;

The unconscious ones' injuries were unknown; they might be the least injured;

And those screaming and crying indicated that the wounded were conscious and perceiving normally, their overall condition was not bad, and the hope for successful treatment was greatest.

At this time, Lin Jie found himself alone at the scene. After making his judgment, he approached a young man wearing a tie who was crying and clutching his lower leg.

His right lower leg had an open fracture, the leg bone pierced the skin and was exposed, with blood gushing out; it should be a major blood vessel injury in the calf.

Lin Jie first needed to stop the bleeding!

"Don't panic, I'm a doctor, I'll help you stop the bleeding first. The more nervous you are, the faster the blood will flow!"

While comforting the young man, Lin Jie quickly untied his tie and fastened it above the right knee with a dead knot.

He picked up a chopstick from the ground and inserted it into the knot, quickly twisting it tight.

With maximum force, he twisted the tie tightly, significantly reducing the blood flowing from the leg bone wound!

Lin Jie pressed the injured man's hand against the chopstick, shouting, "Hold down this chopstick; if you don't want to die, don't let go!"

After saying this, Lin Jie began to examine the young man's body!

His hand started from the young man's head, moving downward, neck vertebrae, chest ribs, abdomen, pelvis, arms, thighs!

After a quick examination, Lin Jie knew the situation and shouted to the youth, "You only have a fracture in one of your ribs, but no obvious internal organ injuries."

"As long as you hold onto that chopstick, you are temporarily not in any life danger. Wait for the ambulance in peace!"

"Help! Save my girlfriend! Save my girlfriend!"

Just as Lin Jie stood up, he saw a man with a darkened face shouting in panic, carrying a long-haired girl to the vicinity.

He quickly instructed the man to put the girl on the ground and began checking her injuries!

This girl had already fainted, with several pieces of glass stuck in her face, continuously bleeding, looking somewhat terrifying; luckily, her eyes weren't injured!

Lin Jie found her breathing normal, carotid pulse strong, checked the pupils by flipping the eyelids, and found they were equal and normal, then checked the girl's chest and abdomen sequentially.

He stood up and said to the man, "Your girlfriend is only slightly injured; she fainted, but she's fine!"

The man breathed a sigh of relief, saying, "Thank you! Thank you! Ouch..."

With these words, he touched his butt, pulling out a palm-sized piece of glass!

"Damn..."

Lin Jie was momentarily speechless and saw a fountain of blood spraying from the man's hips, even hearing the "hissing" sound of blood spraying.

Surely, this piece of glass had injured the femoral artery in his buttock, and it was initially blocked by the glass, making the wound unobtrusive!

Lin Jie couldn't waste time scolding the man's reckless actions and quickly instructed him to lie down!

The scene before Lin Jie was shocking; dozens of pieces of glass of various sizes were densely stuck on the man's back, resembling a hedgehog.

He must quickly stop the hemorrhage from the femoral artery, or else he might bleed to death before the ambulance arrives!

"If you don't want to die, bear with it!"

Lin Jie shouted, amidst the man's cries, used a piece of glass to directly cut the man's hip wound further until he could see the femoral artery and bleeding point.

Then, Lin Jie pinched the blood vessel with his hand, preventing it from continuing to bleed.

"Lin Jie, what can I do?"

When he looked up, he saw Zhang Xiaoxiao standing nearby, somewhat panicked.

"Come here, listen to me!"

When Zhang Xiaoxiao squatted in front of him, Lin Jie placed her hand on the wound, guiding her fingers into the wound, and said sternly, "Can you feel it? This is the femoral artery."

"You must pinch it to prevent it from bleeding further until he is taken to the hospital."

Zhang Xiaoxiao's face immediately turned pale, but she nodded heavily. Once Lin Jie let go, she quickly pinched the artery wound.

"Pinch it tight, and don't let go!"

Lin Jie shouted at her and ran to another person lying down.

This person was half-immersed in a pool of blood, face pale, and when he saw Lin Jie running over, he whispered, "Help me! Help me!"

Just as Lin Jie was about to bend over to check this person's injuries, his arm was suddenly grabbed, as if clamped by iron pliers, causing pain.

He was dragged involuntarily in another direction, while an anxious male voice shouted beside him, "Save my daughter, save my daughter first!"

Lin Jie stumbled as he was dragged forward more than ten meters by the middle-aged man, stopping in front of a fourteen or fifteen-year-old girl, his face changing.

This girl, for some unknown reason, her face had turned blue and purple, a sign of severe hypoxia.

He quickly squatted down, straightened the girl's head and neck, and pried open her mouth, finding her throat swollen.

This was her airway being blocked; CPR was no longer effective, and her trachea needed to be cut open.

"Do you have a knife? I need a knife!" Lin Jie shouted!

The middle-aged man was also extremely anxious, shouting to people nearby, "Knife! Knife! Does anyone have a knife?"

Lin Jie was also worried; time was running out.

If a person is deprived of oxygen for more than 3 minutes, irreversible brain damage may occur; more than 4 to 6 minutes can lead to brain death.

From the girl's blue-purple face, she had been without air for some time.

Lin Jie glanced around and suddenly saw a discarded yogurt box with a straw inserted in it about three or four meters away!

His eyes brightened, and he quickly ran over to retrieve the straw.

Back next to the girl, Lin Jie touched and identified her trachea with his left hand, holding the straw in his right hand with the sharp end towards the girl's throat, swiftly and forcefully stabbing down.

The straw pierced through the skin of the girl's throat with a pop.

Lin Jie immediately heard the sound of air hissing through the straw, and at the same time, the blue-purple hue on the girl's face began to fade rapidly.

Lin Jie breathed a sigh of relief, successfully saving the girl!

Quickly checking the girl's body, when he stood up, he saw the middle-aged man running over, holding a small fruit knife, still shouting, "Knife! Knife!"

Meanwhile, the sirens of the fire truck and the ambulance were approaching from afar, and Lin Jie finally released a sincere sigh of relief from his heart.
