Lin Wanqing came to her grandfather and knelt down again, doing cardiopulmonary resuscitation.

Tang Chao commanded: "Force...... The depth is not deep enough ......"

"......" Lin Wanqing increased the strength of her hand.

Tang Chao said: "Hurry up...... The frequency is not ...... enough"

"......" Lin Wanqing sped up the speed of her hand.

Tang Chao said: "Okay....... Stop, artificial respiration. ”

"......" Lin Wanqing stopped her hand movements and did artificial respiration.

Tang Chao said: "Two artificial respirations are enough, and then continue to do cardiopulmonary resuscitation." ”

Lin Wanqing really wanted to slap this student to death. Usually you shout at others, but when is it your turn to shout at others? And this person is still a student who hasn't grown all his hair?

Tang Chao said: "Force...... Don't stop....... Hurry up and ........"

"Force...... It's hard......."

"Hurry up...... Hurry up and ........"

"Don't stop...... Why are you stopping?"

"When have you been staring at me, are you still glaring at me? You are saving people now, and the person you are saving is still your grandfather......

Tang Chao wondered, is this woman sick? After doing cardiopulmonary resuscitation, she stopped to stare at herself, and blushed?

I didn't insult her, it's really ......

He didn't know how ambiguous his words were. For any girl, being surrounded by so many people, she will blush when she hears this.

However, the Tang Dynasty did not know the deep meaning of his words, and even if he knew, he would not pay attention to it, because this was a critical moment to save people.

Originally, the Tang Dynasty didn't know about cardiopulmonary resuscitation and defibrillation, but since I was ready to learn medical skills, I soaked in the library every day these days, and I understood it.

The most important thing in CPR is the depth and frequency of compressions. The compression depth is at least 5CM, and the chest compression frequency is at least 100 times/min, if the compression depth and compression frequency do not meet the requirements, rashly performing cardiopulmonary resuscitation on the patient is not to save people, but to harm people, and it is likely to lead to the patient's "stone heart" situation.

To put it simply, the heart contracts tightly together, becoming like a stone, and it loses its vitality.

This is one of the reasons why many rescuers perform CPR on patients, but the patients are still not saved, which is one of the reasons, because the depth and frequency of compressions do not reach the mark.

Tang Dynasty knew the powerful relationship between cardiopulmonary resuscitation, so he had been using his divine sense to perceive the depth of compressions, and silently counted the frequency of compressions in his heart.

But there is another link that is indispensable, 30:2.

30 is 30 chest compressions, 2 is 2 artificial respirations, that is, 30 consecutive compressions, 2 artificial respirations.

A mistake in any of these links can lead to a rescue failure.

This is also the reason why the Tang Dynasty has been urging Lin Wanqing to follow her.

Under the urging of the Tang Dynasty, she had already done 30:2 5 times, Lin Wanqing was already exhausted, in this still relatively cold weather, she was already sweating, her hands felt unconscious, her compression depth was getting less and less, and the compression frequency was getting slower and slower, but she could only grit her teeth to support it, because she felt that her grandfather's face was a little ruddy, and her nose was breathing.

Suddenly, the old man's breathing became a little heavier, and there were signs of lucidity.

Lin Wanqing didn't dare to relax in the slightest, although she felt that her hands were no longer her own.

"Alright, it's time to stop. Tang Chao said suddenly.

Lin Wanqing breathed a long sigh of relief and secretly scolded that the Tang Dynasty was not human.

As long as you do cardiopulmonary resuscitation training, you know that it is very laborious, and Lin Wanqing is urging by the Tang Dynasty to do such a standard.

The reason why she scolded Tang Chao for not being a human being, because she felt that a Tang Dynasty who was in the prime of life stood by and watched, and let herself, a weak woman who was about to lose her strength, continue to do it, which was very uncomfortable.

But she forgot that there was a large crowd of onlookers around.

The sirens of the ambulance suddenly sounded, and the sound became louder and louder from far to near.

The crowd dispersed automatically, and an ambulance drove up, stopped a short distance away, and three first responders got out of the car.

looked at the motionless lying on the ground, and sighed in his heart: "There is another corpse." ”

This is not to blame them, the success rate of patients with cardiac arrest in Huaxia emergency is less than one percent, which means that one out of a hundred people cannot be saved. So when they arrive, the patient is a cold corpse.

This also made the outside world joke about the first aid team, saying that they were not a first aid team, but a corpse collection team.

When the three first responders put down the stretcher and were about to lift the old man's body, the old man suddenly opened his eyes and startled the three first responders, thinking that he had cheated the corpse.

But after they probed the old man's breathing, they learned that the old man had been saved.

They looked at the stunning woman who was kneeling on the ground and was caring about the old man, and the student who was standing next to the old man, holding the wire in both hands.

It's no wonder they're surprised that cardiac arrest is being revived by non-professionals in the folk, something they've never seen before.

Seeing her grandfather being carried on a stretcher, Lin Wanqing finally breathed a sigh of relief and stood up.

turned around and thanked Tang Chao: "Thank you." Although there was still some resentment in my heart against the Tang Dynasty before commanding me, I didn't have a seizure.

She was just curious why Tang Dynasty still held the wire in his hand, and the posture of holding the wire was so weird, like constipation.

Tang Chao was helpless! His hands had already been lost to the electricity, and he couldn't even loosen the wires.

Before Tang Chao could speak, his body fell towards Lin Wanqing's arms, and the wires were detached from his hands.

At the last moment when Tang Chao lost consciousness, he secretly said in his heart: "It's so big...... It's so soft...... It's so comfortable...... It's like Mom's arms. ”
