After discussing the matters of the next competition, out of politeness, Ji Ke sent the two girls out.

"Eh, what do you see over there?" The three of them stood at the door chatting about leisure, discussing when to bring their respective employees to have a dinner party or something, Gu Yu turned around, but saw that someone on the other side of the road began to gather together, out of the instinct of gossip and joining in the fun, Gu Yu felt that something was going to happen there.

"Someone is lying on the ground!" Ji Ke's eyesight can be said to be the pinnacle of human beings, and he can easily see the situation inside the crowd.

"Let's go, go over and have a look!" Due to the professional characteristics of media workers, Xie Ying pulled out his legs and walked across the road before he finished speaking, Ji Ke and Gu Yu had no choice but to follow.

"Let me see, let me go, what's wrong? Let me see!" It can be seen that Xie Ying is quite familiar with the experience of crowding, and perhaps this is also the characteristic of media staff? In a few words and some pushing and dismantling, it didn't take much effort to squeeze in; the two people who followed behind were stained with some light and entered smoothly.

"Something is wrong," Ji Ke looked at the old man lying on the ground, his face was pale, his eyes were closed, he muttered a sentence in his mouth, and subconsciously stretched out two fingers and put them under the old man's nose.

"Are you alright, old man?"

Ji Ke withdrew his fingers, patted the old man's shoulders with both hands, and at the same time attached to his ear, shouted in a slightly louder voice;

"Gu Yu call 120 and say that we have someone in cardiac arrest here! Xie Ying, let the others disperse! Hurry up!"

Cardiac arrest, a very common public health problem nowadays, is mainly characterized by the sudden termination of cardiac ejection function, aortic pulse, heart sound loss, resulting in external characteristics ---of the face and whole body bruising, pallor, ischemia (pallor), hypoxia (bruising) of various organs of the body (bruising), some patients will have transient limb twitching, incontinence.

The old man lying on the ground in front of Ji Ke is cardiac arrest, cardiac arrest does not exist alone, it is usually one of the side effects caused by heart disease, such as heart disease, myocarditis, cardiomyopathy, heart valve disease, hypertensive heart disease, congenital heart disease, etc.

"Is the heart stopped? Isn't that dying?" A passer-by suddenly burst out, although he didn't understand what cardiac arrest was, but the excellence of Chinese characters made the onlookers know that the old man was not in a good situation just by relying on the four words Ji Ke said.

"Almost, everyone stand outside and leave some space," I took the initiative to encounter this thing, and if I don't have the ability, if I don't make a move, Ji Ke can't get over the hurdle in my heart, as for whether it will be falsely accused in the future, Ji Ke said, go to your sister, don't think about these now.

Needless to say, the harm of cardiac arrest, the rescue is basically a situation of death if it is a little late, fortunately, Ji Ke and they came in time, and it was only two or three minutes before the old man fell to the ground, and there was still time for first aid.

Fortunately, it is now twilight summer, the ground is not very cold, Ji Ke quickly checked the ground behind the old man, very good, there are no hard objects such as small stones;

The hands are interlocked, the heel is placed in the center of the old man's chest--- the lower half of the sternum, the armpit (armpit) is perpendicular to the position of the sternum, the elbows are straight, the arms are vertical, the upper body leans forward, Ji Ke kneels on the side of the old man's body, the thighs rise, and uses the upper body as the axis, not the strength of the arms to press the old man's sternum vertically in the direction of the spine.

There are certain requirements for cardiac resuscitation, and when Ji Ke was studying first aid courses at Huaishen College, the Red Cross staff who came to train emphasized these.

The depth of compression is at least 5 cm, which is equivalent to the width of three fingers in an adult, and the width of four fingers in parallel;

The compression rate is at least 100 times per minute, and it is maintained between 100 and 120 times per minute, the reason why it is this speed is only because patients with cardiac arrest usually have poor heart function and a faster heartbeat rate than ordinary people, and at the same time, after cardiac arrest, the body needs oxygen very much, and the oxygen input from artificial respiration must cooperate with the high frequency of compression speed in order to be delivered to all parts of the body.

During artificial respiration, the position of the patient's head is also important, and the chin must be lifted to prevent the patient's tongue from falling unconsciously to block the airway;

Artificial respiration is not done casually, it is carried out with compression techniques, basically 30 compressions, 2 artificial respirations, each time lasts 1 second, you need to see the patient's chest wall rise and fall when blowing, 500 to 600 ml of air each time--- this amount can basically make the patient's chest wall rise and fall, so you can stop when you see the chest wall rise and fall when you blow.

Compressions and rescue breaths are performed alternately, each of the two movements is counted as a cycle, and after 5 cycles (2 minutes), the patient's response and breathing need to be re-checked, if there is still no response, it is necessary to continue to repeat the compressions and rescue breaths until the patient recovers or the medical staff arrives.

"This young man is so bold, and he is not afraid of getting into trouble!" Ji Ke was busy resuscitating his heart there, and the crowd of onlookers formed a circle at a distance of two meters, and there was a lot of discussion.

"I hope you don't put it on the stall, after all, it's a good deed, not to mention that there is no good reward, don't come this evil reward. Obviously, everyone knows those disgusting things on the Internet, not to mention the truth of the matter, the sentence "You didn't do it, so why did you help it?" completely disgusted everyone.

This kind of suspicion and judgment tendency can be regarded as a complete downward adjustment of everyone's expectations of morality! Everyone still likes to hear about good people and good deeds, and even encourages and supports them, but more importantly, they are wise enough to protect themselves, so that those "stunned youths" whose blood is not yet cold rush to the front, and they stand aside and applaud and cheer.

"Why hasn't the ambulance come yet?!" Although it didn't take a few minutes, Xie Ying and Gu Yu felt that life was like a year, and they didn't want to see Ji Ke get into any trouble because of this matter, especially the old man still has no signs of recovery.

"What's wrong, Xiao Ji?" At this time, Zhen Peng, who was in the studio, also received Gu Yu's message on WeChat, hurriedly suspended the class, and rushed over to understand the situation.

"Brother Peng, come here to help! I can't take care of it alone!" Ji Ke was sweating profusely, he applauded Li Jiang a little too much last night, even if the system was close to him, his physical fitness had not fully recovered until now, and a few minutes of first aid made him a little overdrawn, and when he heard Zhen Peng's voice, he hurriedly asked him to come over to help.

Zhen Peng's professional level is quite good, when he was trained in Huaishen College, if he didn't want to return to Zhengshi to do a career, he would stay in Huaishen College as a rehabilitation teacher;

"Hurry up!" Although Ji Ke left a wisp of internal force on the old man's head to prevent the old man's cerebral edema (cerebral edema after 3 minutes of cardiac arrest), the internal force is not omnipotent, and he can only hang his life, whether he can come back from the edge of the death cliff or not, or rely on scientific means.
