The lower the blood oxygen saturation value, the greater the problem of hypoxia, generally speaking, if it is lower than 90%, people may be in a coma, but how did the oxygen saturation of these two fall to an extremely terrifying thirty or forty percent? It's weird.

His surprise caused Aunt Huang and Fat Zhou to be uneasy, the two looked at each other, and Aunt Huang asked, "Doctor Dai, what's wrong?" Are we sick? ”

Dai Yunyang said: "There is a problem. By the way, I'll see if it's a problem with the instrument first. ”

He took off the blood oxygen monitor on Aunt Huang's finger and clamped it on his finger, and the screen showed a blood oxygen saturation of 97%, which was within the normal range. He took the oximeter on Zhou Fatzi's finger and clamped it on his other hand, and the blood oxygen saturation was still 97%. He couldn't help but sigh again and said, "Something is wrong, the oximeter is normal, why are the blood oxygen of the two of you so low?" Do you two have any bad feelings? ”

Zhou Fatzi said: "I just feel that my chest is very stuffy, and there is nothing else." ”

As he spoke, he moved the breathing mask from his mouth and nose to make it more secure.

Aunt Huang also said: "I just feel a little out of breath, and there is nothing wrong with anything else." ”

As they spoke, Dai Yunyang checked the temperature of their foreheads and felt that there was nothing wrong. There is no problem with the machine, is it a problem with the settings? He immediately adjusted the instrument, but nothing changed.

Wu Hao also came over and asked, "What's wrong?"

After Dai Yunyang said the situation, Wu Hao also checked the oximeter and the machine, and there was no problem either.

He was also puzzled and said, "This is really strange. It's strange that the two of them have blood oxygen saturation so low, but people are fine. ”

Fat Zhou suddenly said, "Doctor, I want to go to the toilet." ”

There are bathrooms in the two intensive care units, and if they can get out of bed and walk on their own, they can go to the bathroom. Zhou Fatzi hasn't started the infusion yet, he is wearing a non-invasive ventilator again, and it should be fine to take off the mask for a while. Until then, he had been using the toilet by himself.

So Wu Hao said: "You go, be careful." Slow down. ”

Fat Zhou sat up slowly, unplugged the oximeter and other wires on his body, took off the mask of the non-invasive ventilator, got out of bed, and walked slowly to the toilet.

Dai Yunyang suddenly felt a twitch in his heart for no reason, as if he had some bad feelings, and hurriedly said, "Wait a minute! ”

Fat Zhou stood still, turned his head back to look at him.

Dai Yunyang said: "You lie on the bed for a while, the blood oxygen saturation of the two of you is so bad, I don't feel at ease if I don't find out the reason." Hurry up and put on your ventilator mask. ”

Fat Zhou walked back again, lay on the bed again, put on a breathing mask, and said, "Doctor, I can't hold it for too long." ”

Dai Yunyang nodded and checked again, and the blood oxygen of the two of them was still very low. He turned his head to Wu Hao and said, "Upper tracheal intubation, right?" ”

Wu Hao was a little strange: "The two of them are fine, there is nothing unusual, why do you need tracheal intubation?"

Dai Yunyang said: "I think it's safer to use tracheal intubation? After all, the blood oxygen of the two of them fell so badly, they both fell to thirty or forty, and it stands to reason that with such a low blood oxygen, people would have passed out a long time ago, and most of their hearts had stopped. ”

"That's right!" Wu Hao also felt that something was wrong, and slapped it twice on the monitor, and found that the blood oxygen saturation still had not changed, and it was still at an extremely terrifying value.

Wu Hao gritted his teeth and said, "Since this is the case, for the sake of safety, hurry up and insert the tube." ”

Fat Zhou hurriedly waved his hand: "Is the intubation a tube inserted from the throat?" The pain is dead, I'm fine now, I don't plug in! ”

Aunt Huang was very scared, because she felt that her breathing began to become difficult, and said, "I feel very uncomfortable now, doctor, do you breathe better after intubation?"

"Of course, the intubation is to insert the tube directly into your lungs, which can deliver oxygen directly to your lungs, and of course you don't have to work so hard."

"Then plug it in for me."

Aunt Huang actually only has a slight purple lips, which is much more stable than the kind of patient who is very scary at first glance, and the blood oxygen saturation is very bad. Just looking at her appearance and breathing, Dai Yunyang would not do intubation on such a patient, after all, intubation is extremely painful and uncomfortable for others, but in the current situation, he feels that he would rather be intubated ahead than have an accident.

Wu Hao called an anesthesiologist from the intubation knife class to assist Dai Yunyang in intubation. Plug it in Aunt Huang first. If the patient refuses to be intubated while awake, the doctor cannot force it, because the treatment is voluntary in principle, and the doctor cannot treat the patient who does not want to, even if this treatment is beneficial to him.

Intubation is quite uncomfortable when the person is awake and must be under local anesthesia.

After the anesthesiologist administered the anesthesia, Dai Yunyang began intubation. He was familiar with the road and was intubated in less than a minute.

The blood oxygen saturation on Aunt Huang's monitor rose rapidly, until it returned to above the 90% passing line, and the screeching alarm sound had stopped.

At this time, Fat Zhou took off his breathing mask and said, "I can't hold it back, I want to go to the toilet." ”

He didn't even care about the consent of the attending doctor Dai Yunyang, so he got out of bed by himself, pulled on his shoes, and walked towards the bathroom with some staggering.

He had just reached the bathroom door when he suddenly stopped, and then, with his hands on his chest, turned back with difficulty.

Dai Yunyang and Wu Hao suddenly saw his purple face.

Immediately, he pushed Jin Shan down like a jade pillar and fell forward, his huge and bulky body slammed into the ground, and almost everyone next to him felt the shaking of the ground.

Dai Yunyang hurriedly stepped forward to check, and found that this time it had broken the bridge of his nose, and blood flowed, but the whole person did not react.

Dai Yunyang shook his shoulder and called him: "Fatty, can you hear me?" What happened to you? ”

There was no answer, and holding his head didn't feel like holding a living person.

Several patients had already died at his hands, and Dai Yunyang was already familiar with a dead patient, and the heaviness of his body was obviously different from that of a living person. Now Dai Yunyang once again feels this difference.

He was startled, and quickly touched the fat man's neck carotid artery with his hand, but he couldn't feel the slightest fluctuation.

The male nurse Kang Zhuang and others hurriedly came over to help, and laboriously flipped Zhou Fatzi over, and Dai Yunyang checked and found that his pupils had dilated. I took a small flashlight and shone it to my eyes, and my pupils no longer reacted to the light.

Dai Yunyang shouted loudly: "Hurry up, carry the patient to bed, the patient's heart has stopped." ”

Everyone carried Zhou Fatzi back to his hospital bed with great difficulty.

Nurse Wang Bingbing and others quickly reconnected the ECG monitor and other instruments, and the ECG waveform displayed on the machine became a straight line.

Dai Yunyang still worked with the male nurse Kang Zhuang for more than half an hour to perform cardiopulmonary resuscitation, but there was no effect until he was exhausted.

Wu Hao finally announced Zhou Fatzi's death.
