The two of them snuggled happily, only caring about sweet whispers, but they didn't know that a storm was about to come outside.

"Tell me, my dear, under what circumstances do you have to do artificial respiration? In case of such an emergency in the future, I will rush to the rescue of the patient! Moved by the sonorous words of the lover's righteousness, Yang Zijiang himself was a little eager to try.

"Well, I know that the person I love is the noblest, bravest, and kindest man!" Liu Li encouraged and praised her, and while confessing her mood, her tone was very proud, but she also reminded her lover,

"But you also have to pay special attention to this matter, first, because you are not a medical professional, and second, because you are a man, there are still some taboos,"

"Huh? You just said from time to time that you save lives and help the wounded, life and death, what? Yang Zijiang was a little puzzled.

"You only know one thing, you don't know the other, in our society, folk customs are different, moral and ethical constraints are strict, you are different from me, because you are not a doctor, but also a boy, so naturally you have to pay extra attention." Liu Li explained, "In a state of emergency, women are fine against men, but if you take a mouth-to-mouth approach against women, it will definitely cause trouble, mainly because you are not a doctor?" ”

"Then according to what you said, I can't save people in an emergency?"

"I can't say that completely, if it's not a full-time medical professional, just a member of the public, then I suggest that you can take the method of 'mouth and nose breathing' when rescuing,"

"Mouth and nose breathing?"

"Yes, this operation method is originally because some patients have trauma to the mouth, or the mouth cannot be opened for other reasons, the method of mouth and nose blowing is more suitable for the public, and the rescue in an emergency is naturally suitable for you,"

"Hey, this is good," Yang Zijiang was happy, "Tell me how to do it?" ”

The specific operation method is that the patient's head is tilted back, and the rescuer supports the patient's jaw with his hand to keep her mouth closed. Then, take a deep breath, wrap your mouth around the patient's nose, and blow firmly into the patient's nose until her chest lifts. After blowing, release the patient's mouth and let her exhale the air. To determine if this method is effective, you can observe the patient's chest rise and fall and feel the airflow exhaling! ”

"Why is that?"

"Because artificial respiration is to ensure an uninterrupted supply of oxygen to dying patients, the main purpose is to prevent irreversible damage to vital organs caused by short-term hypoxia."

"How much oxygen can I get in one breath?" Yang Zijiang disagreed.

"Don't take this breath seriously, if you are really under the water, when you can't catch your breath, this breath can save your life!" Seeing that Yang Zijiang didn't seem to believe it, Liu Li not only explained to him, but also asked him, "Do you know what is the concentration of oxygen in normal air?" ”

"I know, under normal conditions, the oxygen content is about 21 percent,"

"But after breathing into the lungs, do you know how much our body can use?"

"I really don't know this,"

"I'm telling you, only 3 to 5 percent of them can be utilized,"

"Huh? So little? Isn't that a waste? ”

"So, after scientific research, in the normal exhaled air, there is also 16% to 18% oxygen concentration, then, when we carry out artificial respiration, as long as the amount of air given to the patient is slightly larger, we can ensure the normal supply, you think, so high oxygen content, not less than spontaneous breathing. In this way, the normal oxygen supply to the vital organs in the patient's body can be guaranteed, and the damage to vital organs such as the brain, such as the brain, will not be caused by a temporary lack of oxygen! It was the first one that was easily damaged, and once the damage was severe, even if the patient was rescued. Will it also cause great harm? You say, don't you? ”

"Well, that makes sense, that makes sense!"

"In addition, when you blow into the patient's mouth, pay attention to blowing 2 times in a row, and the blowing time of each time is about 1~1.5 seconds, and the blowing volume is about 1000 ml until her chest is raised. Then stop blowing, release the mouth that is close to the patient, and relax the hand that is pinching the nostrils, turn your face to the side, and listen with your ears for any airflow to come out. Then, take another deep breath of fresh air in preparation for a second blow. When the person has finished exhaling, the person begins the next blow of the same breath. ”

"Understood,"

"If the patient does not regain spontaneous breathing, the frequency of continuous insufflation is 12 times a minute for adults, 15 times a minute for children, and 20 blows a minute for infants. One thing must be noted that when blowing, the capacity of the blow is more important than the frequency of blowing, the first two blows, each time to last 1~2 seconds, let the gas completely discharged and then blow again, check the carotid artery, pulsation and pupil and skin color within one minute, until the patient recovers successfully resuscitated,"

"So exquisite?"

"Well, you think it's just a blow? Come, I'll show you, you tilt your head back, like this," Liu Li demonstrated, she held Yang Zijiang's chin and pinched his nose, "Attention, I'm going to blow!" ”

Then, she naughtily blew into Yang Zijiang's nose.

"Well," Yang Zijiang took a deep breath, "Hehe," he couldn't help but laugh,

"What are you laughing at?"

"Xiang, you are so fragrant," I don't know if it was because it was too close, or because Liu Li's movements stimulated him, Yang Zijiang became excited all of a sudden, he hugged Liu Li vigorously and pinched her chin, "Honey, I want to intern!" He opened his mouth wide and exaggeratedly said,

"Go, you're bad!" Liu Li was shy, twisting her body, which made Yang Zijiang even more irrepressible.

"Smack!" Just when the two of them were making a lot of noise and being happy, there was a sudden knock on the door.

"Mom, who is this?" The two of them immediately held their breath, not daring to make any sound.

"Come out, I've got you!" The people outside deliberately lowered their voices to scare them.

"Shh," Yang Zijiang put his finger to his mouth and motioned for Liu Li not to speak.

"Bang bang," I didn't expect that the people outside were energetic, not only knocking on the door of the passage even harder, but also saying their names, "Liu Li, Yang Zijiang?" I see you, come out obediently, right? ”

"What can I do?" People obviously know their names, so they can't go out? But once you get out, if it's a political commissar, it's over.

They knew that if they were caught by the leaders, what was waiting for them would be repatriation, which was terrible, and the two of them were suddenly scattered......
