Cardiac arrest also has a low survival rate in later generations, let alone in ancient times. Cardiopulmonary resuscitation is not a miracle skill, and there is no guarantee that every patient will have a chance to regain spontaneous breathing and heartbeat, but at this moment Madu has no other way.

As soon as he stopped, Chang Yuchun's last hope of survival was cut off. However, Madu was very tired, and he was exhausted from a night of running, and dozens of minutes of cardiopulmonary resuscitation in a row almost squeezed out his last trace of physical strength.

Knowing that today, Ma Du should have taught the methods of cardiopulmonary resuscitation when he was in Hongdu. The reason why it was not taught to others was not to keep a hand, but because those wounded soldiers who were rescued from the battlefield could not use this trick, and all that was needed was in the pile of dead people, and no one would spend great effort to rescue a dead person.

So much so that Madu now didn't even have a helper who could replace him, his wheezing was getting heavier and heavier, sweat soaked the clothes on his back, beads of sweat kept sliding down his face, and the muscles in his body began to cramp because of the long-term tension.

Ma Du couldn't hold it anymore, but Chang Yuchun's eyes were closed and his expression was stiff, and there was no sign of recovery, and he was ready to use the last resort. He also has a booster shot, the only one in the first aid kit, but it has been expired for a long time, and the ghost knows how many drugs work.

Knock, knock, knock......

The drums outside the tent sounded, it must be Li Wenzhong who was raising the tent to appease the soldiers, if he can successfully take over the army, this time the task will be half completed, as for Chang Yuchun, he may really not be able to escape this catastrophe.

He was about to withdraw his hand to get the heart booster, but he heard Xu Daliang whisper: "Sir, the handsome heartbeat seems to be there." ”

Madu shook his head, "That'...... It's me...... Compression! ”

Xu Daliang said: "No, it's different from the rhythm of your pressing!" ”

"Really?" Ma Du hurriedly trembled and put the stethoscope in his ear, put his head on Chang Yuchun's chest, and sure enough, he heard the sound of heartbeat, but it was relatively slow and weak, and his breathing was also weak.

Ma Du was overjoyed, "How old is Lao Xu for a while?" ”

"Hmm...... It was about the time when the drums were beating outside. ”

His mother is really a killer, Ma Du did cardiopulmonary resuscitation for a long time to no avail, and when he heard the sound of war drums, he actually reacted, no wonder the rhythm of this heartbeat is similar to the sound of war drums.

Ma Du handed the stethoscope to Xu Daliang and asked him to continue to monitor Chang Yuchun's heartbeat. He opened the first aid kit with trembling hands, not agitated but convulsive.

Chang Mao and Lan Yu saw Ma Du's happy face, and immediately became excited, and asked in disbelief: "My father (brother-in-law) is really alive!" ”

"Well, yes, but it's not stable yet!" He took out the syringe and slowly pumped the potion into the syringe.

Chang Mao patted Ma Du on the shoulder vigorously, "Brother Du, you are really a god, our whole family is grateful to your eight ancestors!" That sounds like an insult.

Ma Du's hand fell directly to the ground with a trembling needle, "You can't be honest, if you destroy this medicine, your father will really be hopeless!" Chang Mao was so frightened that he hurriedly stepped aside, not daring to move again.

Xu Daliang suddenly turned around and said, "Sir, the handsome's heartbeat seems to be weaker." ”

The drums outside had long been silent, and Ma Du hurriedly said: "Lan Yu told the person in charge of beating the drums, let him continue to beat harder, and the rhythm should be a little faster than just now!" What are you doing in a daze, hurry up! ”

Although he didn't know what the drumming had to do with saving people, Lan Yu still did what Ma Du said. When the drum sounded outside, Ma Du had already inserted the needle into the thick veins on Chang Yuchun's arm and slowly pushed the medicine in.

I don't know if it's because of the war drums or if the expired medicine has worked, but after two or three minutes, Chang Yuchun's heartbeat and breathing have become more and more powerful and stable, but it's still a little weaker than normal.

Lan Yu came back from outside the tent and felt Chang Yuchun's breathing and heartbeat, tears of joy welled up in his eyes, he pulled Chang Mao and fell to the ground directly at Ma Dubai, "Great grace is not grateful, please accept the two of us, as long as you can use Lan Yu and Chang Jia's place in the future, although Lord Ma speaks, he will never frown in the water and fire." ”

Are you kidding! Except for Lao Zhu, who dares to use the two of you, don't you want to die?

Ma Du hurriedly dodged away, "It's still early to say thank you, Chang Shuai is only out of danger temporarily, it's hard to say whether he can survive or not." His face suddenly turned cold, "Chang Shuai insulted me very deeply, I still hate him in my heart, and today's shot is neither for his face, nor for your Lanyu's face." One is for the sake of the army, and the other is for the love with Brother Mao, you and Chang Shuai don't have to accept my love! ”

Chang Mao got up from the ground and said with a smile: "Uncle, you are too outside, and you don't see what kind of friendship I have with Brother Du, when we go back to Yingtian, I will invite you to Qinhuai River to live happily for a few days!" Brother Du, you didn't sleep all night yesterday, let's find a tent and rest quickly, my dad is here and I'm watching. ”

"You don't have to go anywhere else, just spread a blanket for me here, if Chang Shuai's condition recurs, it's also convenient!"

Ma Du didn't rush to sleep, and first taught cardiopulmonary resuscitation to Xu Daliang, this guy thought it was some kind of thaumaturgy of life and death if he got the treasure. Waiting for Xu Daliang to feed the decoction to Chang Yuchun, there was no bad reaction, Ma Du then lay down on the blanket to sleep, the wound on his buttocks was cracked, and he could only use this position.

Chang Mao leaned over and lay down next to Ma Du, "Brother Du'er really thanked you this time!" You know, in the morning I thought my dad was really going to die, and I was terrified! If my father died, my mother would definitely die of sadness. ”

Ma Du smiled and asked, "Aren't you sad?" ”

Chang Mao shook his head, "Hmm...... Don't be sad, I'm already an adult and a man. "If you can say such things, you must still be a child who has not grown up, and I don't know who it is in the morning with a nose and tears.

"Brother Du, when do you think my father will wake up?"

"This ...... It's hard to say, he's so tired that he might have to sleep a few more days. Ma Du said in his heart: "Maybe he will never wake up!" ”

When a person's heart stops beating for five minutes, it will cause serious damage to the brain due to lack of oxygen, and Ma Du estimates that Chang Yuchun's heart stopped for about three minutes before he performed CPR.

With Chang Yuchun's steady breathing and heartbeat now, it should be possible to wake up quickly, since there is no now, this brain damage may have formed. As the most sophisticated instrument of the human body, the slightest damage to the brain may cause serious consequences.

Stupid, paralyzed and even a vegetative person who can never wake up, even if he is still alive, the name of "Chang 100,000" will become a thing of the past, and Daming will lose an invincible general after all.

(Will such an arrangement be scolded Cheng Xiang?) I'd like to hear your opinions)
