Under the full burst of speed, under the shocked and admiring eyes of the invigilator at the finish line, Xia Yeling persevered to complete the 42-kilometer naked wind and snow penance, and surprised everyone to win the first place in the first marathon test.

The most important thing is that he only took only 59 minutes and 37 seconds to complete the whole race, and he has successfully broken the A-level record of one hour and three minutes held by Shan Rudai!

However, there is a delay in the collection of data by the speedometer on the sidelines, and the specific uniform and maximum speed data of the first marathon run test will take a while to be displayed on the big screen in the test room where the final result is recorded.

Instead of shouting and celebrating the victory, the Summer Night Spirit returned to normal in the form of jogging, and the joints, ligaments, and muscles relaxed from the tense and stretched state, and carefully did the relaxation activities after the long run, preparing to immediately perform the next agility test in the best condition.

At this time, a series of familiar system prompts sounded in the ears of the Summer Night Spirit again-

"Congratulations on triggering and successfully completing your first glorious achievement, [Wind and Snow Penance. Bone-Eating Cold] to receive a reward of 500 honor points. ”

"System prompt: Consume 300 honor points, and the system exchange function is on!"

"There are currently 200 honor points remaining. Currently exchangeable items: Thief's initial space backpack, which requires 500 honor points, 16 squares, 1 cubic meter of storage space per square, and can continue to consume honor points to upgrade. ”

"Congratulations, you've gained Primary Frost Resistance!"

"Beginner Frost Resistance: You have successfully completed a grueling Storm Penance, which slightly increases your Frost Resistance by giving you full immunity to natural Cold damage below 45, which makes you more comfortable with fighting in freezing conditions. Also, when you're attacked by a direct-damage soul ability, the damage against a first-tier Frost soul ability is reduced by 25%. ”

Sure enough, the effort will be rewarded, and all the tragic frostbite on Xia Yeling's body disappeared and healed in an instant, and his physical state immediately recovered from exhaustion to health.

And successfully completed the [Wind and Snow Penance. Bone Erosion Cold] Challenge Achievement, he felt unprecedented comfort and happiness in his body and mind, high morale, and his will momentum had reached an unprecedented peak after this crazy and cruel tempering, and the precipitated martial arts state of mind was sharpened as a rock and unshakable!

But before he could take a closer look at the details of the newly appeared extremely precious and much-needed exchange function and primary frost resistance on the character attribute panel, a loud exclamation suddenly came from behind him.

Xia Yeling turned around and looked at him in some surprise, only to see that Shao Yang, the simple-minded young man with a flat head who had just joked with him, was lying upright on the ground at this time.

His complexion was abnormally cyanotic, and his formidable body of a Refining Martial Artist actually showed uncontrollable spasmodic convulsions and rigidity!

Oops, it's most likely a sudden cardiac arrest!

Xia Yeling usually likes to borrow books in the library of Rock Academy, and he clearly remembers that one of the medical books was introduced in detail-

1. Acute pallor or cyanosis, 2. Spasmodic rigidity.

Judging from the symptoms shown, Shaoyang's physical symptoms are very likely to be due to the sudden cessation of effective cardiac contraction and pumping functions caused by a severe blow, and severe ischemia and hypoxia caused by the interruption of normal blood physiological circulation, that is, cardiac arrest!

And what is even more terrifying is that once cardiac arrest occurs, if it is not timely and effective rescue and resuscitation, it will cause irreversible and serious damage to the patient's brain and other important organs and tissues after four to six minutes!

Therefore, the four minutes after cardiac arrest is the golden time for rescue, and it is necessary to race against time to immediately rescue the patient, and not delay for a second, this is a race against time against death!

If it was a slut like Gong Fanlin who was full of evil and suddenly had such a crisis situation, Xia Yeling was not the kind of virgin bitch with a moral fetish, so she would inevitably run forward happily and sing and dance around him.

But Shao Yang, a deep brainless fan who loves him and Gong Fanlin's eldest brother, although he lacks a heart and eyes, but his mind is very simple, and he is not bad in nature.

What's more important is that 'a spark can start a prairie fire', every living force of human beings after the end of the world is extremely important, Shao Yang is too young to die worthless in today's graduation examination room.

The medical rescue team in the examination room did not know when they would arrive at the scene, and every second of early rescue was extremely valuable, so Xia Yeling, who had just completed the first marathon test, did not blindly go to the second agility test in order to achieve better results.

After thinking for a while, Xia Yeling immediately turned around and ran at full speed to the place where Shao Yang fell, who was not far from him, ready to give him first aid.

Running to Shao Yang, who was lying prone on the ground, Xia Yeling first identified and assessed Shao Yang's specific situation.

Xia Yeling patted Shao Yang's shoulder and shouted to him loudly to determine whether he was conscious, and at the same time touched the major artery in the sternocleidomastoid groove next to the thyroid cartilage in his neck.

The medical book emphasized that the time of the test must not exceed ten seconds, and after Xia Yeling quickly assessed the test, he found that Shao Yang at the scene only had a faint breath and was unconscious, and the major artery in the neck did not have any pulsation.

-- Cardiac cardiac arrest can be identified.

Xia Yeling immediately decided to perform unarmed CPR on him as described in the medical book, to prevent his vital signs from disappearing before the school's professional medical team arrived.

First of all, Xia Yeling took action to change Shao Yang's prone position on the ground, ensuring that he was lying on his back on the flat ground of the track, and immediately began the most important item of CPR on him - chest compressions!

Xia Yeling used the sternal stem between Shao Yang's sternum and the two nipples-head connections as the best point of focus, with his hands folded, his wrists crossed, and his arms perpendicular to the surface of the chest.

Instead of using the center of gravity of both palms, press the base of the palms at the optimal point of force to begin chest compressions quickly and uninterruptedly.

And Summer Night Spirit still clearly remembers that there are four indispensable points of chest cardiac compressions-

1. Press hard, the depth of the pressure is at least 125 pixels, and the best effect is that the sternum is concave into a 'person'.

2. Rapid compressions, more than 100 times per minute.

3. Chest compressions should not be interrupted for a moment.

Fourth, the compressions should ensure that there is rebound, and the chest should be completely restored after each compression. The compression time and the recovery relaxation time each account for about 50%, and the base of the palm cannot leave the chest wall when relaxing, so as not to cause the displacement of the compression point.

…… One hundred ,...... Two hundred, press, reply, press, reply!

Whew! Whew! Rapid and forceful chest compressions are physically demanding, even more tiring than immediately taking a second agility test. Xia Yeling, who had just finished running the marathon test, was exhausted and panting for breath under the tense and fast single-handed rescue, and the sweat also ran down his ** chest and continued to fall on the snow-covered track for a moment, and the heat emitted by the sweat even soaked and melted the snow around him.

The yin wind roared, and the snow was getting heavier and heavier, if it weren't for the summer night spirit, he had just awakened the primary frost resistance, and he would have been rescued naked under such a cold and harsh wind and snow, and he would have been tired even after a quarter of an hour, and then he would have froze and die suddenly.

And the group of students from the privileged elite class who had just gathered together with Shao Yang were now all panicked and scattered in a panic for fear of avoiding them, forming a small unmanned vacuum around the two of them, so as not to be infected with bad luck and affect the results of their marathon tests, and the helpless Summer Night Spirit could only rescue alone.

Unable to find any helper, Xia Yeling did not hesitate to start Shao Yang's second first aid measure - opening the airway under the emergency situation of rapid and powerful chest compressions that did not dare to stop for the slightest.

In order to prevent Shao Yang's tongue from falling down and blocking the airway in the supine position in a coma, Xia Yeling decided to use the 'head and chin lift method', that is, let the patient's head back and chin up to help Shao Yang regain his breathing.

Another important aspect of single-handed CPR is that you can use your hands before you move your mouth.

Artificial respiration is not the most important thing in manual CPR, if you want to save people, simple chest compressions are also very effective, and because Shaoyang still has a faint breath.

Xia Yeling, who did not have much energy to distract from the rescue alone, decided not to use the third artificial respiration on Shaoyang for the time being, with a ratio of more than 1 second each ventilation, 30 chest heart compressions, and 2 artificial respiration ventilations.

But a minute, two minutes passed, and the unconscious Shao Yang still did not see the slightest sign of getting better and waking up.

Exposed to the wind and ice, the eyebrows, hair and chest of the Summer Night Spirit were gradually covered with layers of snow, and the sweat mixed with the snow melted by the body temperature was dripping down, but he didn't dare to have even the slightest slackness, and the Summer Night Spirit who was extremely focused and nervous inevitably felt a trace of tiredness.

―――――――

"Hahaha, God help me! Xia Yeling, you heartless fool-bastard, you actually wasted your precious exam time for a cheap dog I raised that lost its usefulness?! ”

Gong Fanlin, who had exposed his despicable nature in front of everyone, finally caught up with the huge gap of more than a full circle between him and Xia Ye Ling, and was about to make a final sprint, when he passed by Xia Ye Ling, who was independently performing hand-to-hand first aid, he suddenly laughed arrogantly and sarcastically.

"I've been busy for so long, why hasn't Shao Yang reacted, look at your hypocritical pretense, what are you pretending to be! If you don't take the agility test immediately, you will be disqualified from the exam! Even if you run the marathon first, what can you do? Look, the first place in the first level of the Refining Martial Arts Level Test is still me! ”

But Xia Yeling was in a hurry to rescue Shao Yang, and he didn't even pay attention to his provocations, and he didn't even despise him, he simply ignored him.

Gong Fanlin, who was desperate for the final victory, could only continue to sprint to the finish line with all his strength in frustration and resentment, to fight for the second place in the marathon long-distance running test, and race against time for the following test.

The group of freshmen and sophomores who had been watching the graduation test carefully in order to accumulate test experience in the examination room were all boiling and talking.

"Oh my God! I also know how to do medicine, the male god marries me! ”

"Oops, hey, Senior Xia Yeling is so responsible in everything he does, I'm going to faint when it's over, begging to be rubbed and hugged!"

"Gong Fanlin is really a shameless villain! That senior just helped and supported him so much, not only did he not help with first aid, but he even ridiculed loudly, people can be so despicable! I used to admire his strength, I'm blind! ”

"We couldn't go down to help, it disrupted the discipline in the exam room. Come on, Senior Xia Yeling, please come quickly from the medical team in the examination room! I hope they can save that senior in high school! ”

PS1: After the on-site evaluation of cardiac arrest, the correct first aid sequence is chest compressions - open airway - artificial respiration - early defibrillation.

Artificial respiration is too basic.,The author won't write carefully.,If you have the heart, I hope you can check the information yourself.,Especially the specific teaching video.,It's very practical.,If it's inappropriate, please correct.。

There have been so many news of sudden accidental death recently, even if you don't have a first-aid qualification certification, if you encounter this situation in a public place, you should at least shout for help and call 120!

There have been so many news of sudden accidental death recently, even if you don't have a first-aid qualification certification, if you encounter this situation in a public place, you should at least shout for help and call 120!

Very, very, very, very important, so say it twice!

Moreover, the globally recognized 'first life-saving technique' [CPR] and the [Heimlich maneuver] when choking are essential skills for men, I will talk nonsense.

PS2: Happy May Day, everyone!!! I'm really tired and confused today.,If you read it, please squeak it or something......
