It is a manifestation of the increase in deoxygenated hemoglobin in the blood causing the skin and mucous membranes to turn purple.
To explain it simply...
First of all, we need to understand why human blood is red?
Because red blood cells contain hemoglobin.
When hemoglobin is fully combined with oxygen and becomes oxyhemoglobin, it is bright red; when it releases oxygen, it becomes deoxygenated hemoglobin, which is dark red; and when it passes through human skin, it will appear blue-purple.
.
A key element here is ‘oxygen’. Where does the oxygen in the human body come from?
breathe.
To give the simplest example, if one person pinches another person's neck, the latter will turn blue. This is a change in hemoglobin caused by hypoxia, which is the occurrence of cyanosis.
In addition to respiratory system disorders, there is also the problem of cardiopulmonary failure. The lungs are linked to the respiratory system, which can also be associated with the above conditions. Heart problems are not difficult to understand. Blood supply center... blood flow and circulation disorders can also cause
The occurrence of cyanosis.
One branch of congenital heart disease is 'cyanotic congenital heart disease'.
And now.
In the arms of an old man who was stumbling down the street, he was holding a child with a purple lip and a bruise on his cheek——
Cyanosis!
It’s terrible!!
Even Zhou Shouming was stunned for half a second when faced with such a situation, but it was Zhou Sheng who took three steps to knock open the glass door, rushed to the old man, picked up the child, twisted his head and rushed into the clinic. The first sentence
Shout out the words——
"Call 120 and call an ambulance!!"
Isn’t saving people the first priority?
Please find out, please. The condition of cyanosis is extremely complicated. There is no way to solve it just by looking at the situation in the clinic. Traditional Chinese medicine has made no achievements in first aid. Zhou Yisheng often sees the protagonist in traditional Chinese medicine novels taking out a silver needle and performing something like "Return to Heaven in the Thirty Years"
Eight needles, nineteen needles that can change one's destiny against fate, will make you smile bitterly.
Brother, can we follow some logic?
The earlier the ambulance arrives, the higher the patient's probability of survival.
No matter what situation you face, it is correct to call an ambulance as soon as possible. Even if there is a doctor present, compared with the comprehensive equipment of hospitals and emergency centers, the presence of doctors only delays the patient's time and cannot be 100% guaranteed.
Complete treatment.
"Old Zheng, what's going on?" Zhou Shouming came to his senses and recognized the old man and old lady in front of him.
The old lady cried immediately, howled loudly, hugged grandpa, and shouted: "Old Zhou, Old Zhou, please save the child, please, I'm begging you, wuwuwu..."
"
Family members in emergency situations are definitely the most troublesome ones.
Doctors are not omnipotent. They cannot see the symptoms with the naked eye and cannot accurately prescribe the right medicine. When the patient does not have the ability to speak, family members have the unique ability to elaborate on the symptoms. If they do not explain the situation clearly, there is nothing the doctor can do.
Half of the mortality rates in emergency centers over the years are due to late rescue, and half of the late rescue is due to family members being emotionally disturbed and not signing for the doctor to prepare for surgery.
Zhou Shouming glanced at the child in his grandson's arms, his pupils were trembling, and he quickly pushed the old woman away and shouted: "Stop shouting, what's the use of crying? If you don't tell me what happened, how can I save people? What do you think, Xiaohu?"
Go to hell?”
The cold shout immediately frightened the old woman. She did not dare to imagine the scene of her precious grandson dying. For a moment, her soul seemed to be frozen, and the tears lingering in her eyes stopped falling.
The panting old man finally realized the crisis of the situation and said quickly: "Just now we were cooking in the kitchen, leaving Xiaohu to watch TV alone in the living room. After a while, I heard the kitchen door ring. When I opened it, Xiaohu was standing at the door.
, speechless, as if he had choked on something. When I went out to take a look, I found that he had eaten jelly by himself, and then..."
"Then I fainted!"
At this time, Zhou Congshu and Sister Liu also came out of the infusion hall.
Hearing this, Sister Liu scolded directly: "I'm convinced, how can you watch the child? Can the jelly be placed where the child can touch it?"
Sister Liu's child is only in elementary school. As a senior nurse, she has seen many cases of "jelly harming people". Considering her position as a parent, how can she not be angry?
After finishing her words, she picked up the phone, walked aside and quickly dialed 120 for emergency help.
Zhou Congshu also looked flustered, with symptoms of cyanosis appearing on his cheeks and lips, and he even fell into coma due to lack of oxygen.
Ten minutes, just ten minutes, can cause brain damage.
Even if the person is saved, he will only be in a vegetative state!
And can't be saved...
The clinic has been open for decades, but there has never been any trouble like this!!
"Save people!! Heimlich maneuver!" After hearing this, Zhou Shouming gave the order.
Zhou Sheng did not pause at all. He held the child's upper abdomen with both hands and began to move it.
How did grandpa know this foreign technique? It was because of 'jelly'!
In recent years, the death of children due to jelly has reached a point that cannot be ignored. Both major tertiary hospitals and small rural medical centers will conduct popular science education on this technique, which is also the most effective way to clear the airway.
Heimlich maneuver, also called Heimlich abdominal thrust maneuver.
The human lungs can be imagined as a balloon, and the trachea is the air nozzle. When the air nozzle is blocked by a foreign body, squeezing the entire balloon will allow the air pressure to compress the foreign body and expel it.
This first aid method is not difficult. If you understand the principles and know the gestures, ordinary people can learn it immediately, let alone a professional medical student like Zhou Sheng.
Zhou Sheng kept pressing and bumping, and after just a dozen times, he was exhausted and sweating profusely.
For no reason, the little tiger in my arms is too fat. He is as fat as a ball. When he hugs his upper abdomen with his hands, he can hardly feel the existence of his ribs. It is all fat. His fatness is far beyond that of a six-year-old child.
Standard, it can be seen how much love and affection Lao Zheng and his wife have for their little grandson.
Seeing that Zhou Sheng was dying, Zhou Congshu ran up and said, "I'll come, I'll change it later!"
Zhou Sheng handed Xiao Hu over. As soon as his father took over, he let out a sigh of relief and was shocked by the weight.
Once, twice...
Four times, five times...
The little tiger did not wake up, but the cyanosis became more intense.
After making the call, Sister Liu came on the phone and took over for her father. While doing first aid, she shouted: "Spit it out, spit it out, spit it out!!!"
But the little tiger is like a rag doll without a soul. It feels like its limbs are swaying as it shakes, like a lump of dead flesh.
Plop.
Lao Zheng and his wife fell to the ground in despair, with tears streaming down their faces.
In this situation, no one paid attention to the two of them, and the atmosphere was extremely tense... From the time the incident occurred to the time the two sent the child to the clinic, no one knew how much time had passed. If the Heimlich maneuver was ineffective, when the ambulance arrived
The child would have been hopeless before, that's for sure.
Grandpa is silent.
Dad's face also showed sadness...
Zhou Sheng's mind was in chaos, and another flash of inspiration flashed——
Tracheotomy!!
As long as the trachea is cut open, the respiratory tract can be restored!
"Grandpa, a tracheotomy can save you, you can save me!!"
With Zhou Sheng's words settled...
The eyes of the grandfather and grandson collided, and Zhou Sheng clearly saw a hint of indifference in his grandfather's eyes...
