He had just hung up the phone when a monitor in a hospital bed sounded an alarm.

He didn't turn his head, and from the direction of his voice, he could tell that it seemed to be his patient, the grocery store master who first came to the hospital and was diagnosed with the new coronavirus.

Turning his head to see that this was the case, he immediately rushed to the side of the bed, observed the monitor, the blood pressure waveform progressively decreased, and his heart rate quickly climbed to 200 beats per minute!

Immediately afterwards, the ECG waveform turned into an irregular tremor, like a seismic wave.

Ventricular tachycardia, ventricular fibrillation!

Dai Yunyang didn't say a word, stepped forward and immediately started heart compression, and at the same time turned his head and shouted loudly to Wang Bingbing who ran over: "Quick, defibrillator!" Ambulance! ”

Xiong Shengnan, the head nurse, came over with a defibrillator, and after a quick preparation, he stepped forward with a defibrillator and said loudly: "Electric defibrillation, everyone retreat!" ”

Dai Yunyang left the patient with both hands.

Bang!

The electric shock caused the huge master's body to violently bounce upwards and fall back to the bed.

Dai Yunyang stepped forward again and pressed his heart.

Effective cardiac compressions are a strong physical work, and a body like Dai Yunyang, if it was usual, he could hold on for five minutes, but now after wearing a second-level protective suit, especially covered by a thick N95 mask, his breathing is restricted, and he is out of breath after only three minutes.

The strong male nurse Kang Zhuang was about to go up to take over, Dai Yunyang glanced at him, he was only wearing secondary protection, he immediately remembered something, and immediately said: "Don't come closer, go and put on a hood mask first!" ”

Cardiac compressions produce a large amount of aerosols, and close contact with patients can expose them to high levels of the virus, which is a great risk, so cardiac compressions must be protected from tertiary protection, that is, wearing an integral hood mask to cover the entire head.

Kang Zhuang agreed, hurriedly went to put on a protective mask, and ran back to replace Dai Yunyang. Dai Yunyang was so tired that he almost collapsed on the patient.

Kang Zhuang took over, and he was usually strong and could hold on for more than ten minutes in one breath, but now, due to wearing an N95 mask and a hood mask, his breathing was severely restricted, and he only lasted six minutes before he could do it.

At this time, Dai Yunyang had already put on a hood mask, and then went on again, and the two alternated.

Xiong Shengnan performed electric defibrillation again, but still did not regain his spontaneous heartbeat. Dai Yunyang and Kang Zhuang continued to alternate heart compressions.

Seeing that they were too tired, the little fat man Zhu Shan couldn't help but step forward and say, "Why don't I replace it?" ”

Dai Yunyang shook his head. Cardiac compressions are exposed to high concentrations of the virus, so it is important to minimize the number of people you come into contact with and avoid unnecessary risks. At present, Dai Yunyang and Kang Zhuang are still competent in alternating between them, so there is no need to let Zhu Shan join in.

Li Yanling instructed the nurses to keep the venous channels effectively open at the same time, infuse or pump anti-arrhythmic, cardiotonic, and pressurized first-aid drugs, and conduct arterial blood gas and venous blood collection and testing.

After three electric shocks and defibrillation, Master Dang regained his spontaneous heartbeat, but soon had ventricular fibrillation again, and he had to start all over again.

Several times in a row, finally, the waveform of the big man's heart did not tremble like crazy anymore.

At this time, the results of Da Da's blood gas showed severe metabolic acidosis and hyperkalemia, and Li Yanling instructed the nurse to urgently filter the blood at the bedside to correct the disorder of the patient's internal environment.

After some rescue, the vital signs of the big man returned to stability.

Everyone breathed a sigh of relief.

Li Yanling looked at Dai Yunyang: "You are so brave, you dare to go up and compress your heart without wearing a hood mask, you are not afraid of being hit?" ”

Dai Yunyang smiled shyly: "Cardiopulmonary resuscitation, every second counts, I don't think so much, it's purely conditioned." ”

"Next time, I'll protect myself first before I go up."

"Hmmm......"

Dai Yunyang nodded, but wondered in his heart, if he had to do it all over again, would he go to find a hood mask first, and then come to cardiopulmonary resuscitation after wearing it?

Probably not, it's a matter of saving lives.

………………

In the ward, Dai Yunyang was busy, and suddenly heard the sound of sneezing, as if he was sneezing with his head covered in the quilt.

Dai Yunyang was a little strange, turned his head to look, but saw that it was the doctor Fu Quan, bending over there, sneezing non-stop.

Dai Yunyang hurriedly walked over, helped him and asked, "Are you okay?" ”

Fu Quan raised his head and startled Dai Yunyang. His expression was extremely painful, and beads of sweat on his eyebrows kept falling, falling on his eyes with a burning pain. Because of the constant sneezing, it was a little crooked, but fortunately I was covered with a thick mask.

Finally, Fu Quan stopped sneezing, and said to Dai Yunyang in pain: "Allergic rhinitis, I am most afraid of humidity and stuffiness. Once it is humid and stuffy, allergic rhinitis will definitely attack, and it is easy to do it without wearing protective clothing before, but it is a big deal to take an anti-allergy medicine and wipe off the nasal discharge. Now there is no way to blow your nose, you can only swallow the snot in your stomach, otherwise it will have to flow on the mask. ”

Dai Yunyang felt nauseous, but there was nothing he could do, this was the pain that Wang Bingbing just said.

Doctors with allergic rhinitis suffer from another kind of pain, and the runny nose can't be blown off, either on the mask or swallowed in the stomach, how uncomfortable it is.

Dai Yunyang didn't have any way to help him solve it, and said: "Wouldn't it be better to take an anti-allergy medicine before coming in next time?" ”

"I don't dare to eat it, I will doze off after taking the anti-allergy medicine, which is very uncomfortable. The whole person is groggy, so how can he treat people? In case of drowsiness, negligence, failure to deal with what should be done, or improper handling, the patient will die. Forget it, it's uncomfortable. ”

Then a few more sneezes came out. He pointed outside and said, "I'll go there and rest." ”

He was afraid that it would affect the rest of the other patients, so he hid in the corridor, sat on a bench to rest, and waited for the allergic rhinitis to get a little better before coming in.

Xiong Shengnan, the head nurse, saw Wang Bingbing holding a nasal intestinal tube and standing next to a patient's bed, with a very strange expression and a helpless look. So he walked over and asked, "What are you doing?" ”

"The doctor ordered me to insert a nasal and intestinal tube into this patient."

"Then plug in, why are you stunned?"

"I tried it just now, but with such thick gloves and protective clothing, the stethoscope can't be used, I don't know how to insert it?"

Wang Bingbing has inserted the nostril intestinal tube many times in normal mode, and he is familiar with the road without any problems. However, now in the state of secondary protection, in order to intubate and add a headpiece mask, the whole head is buckled in the mask, it is more difficult to breathe, the vision is even worse, and the stethoscope cannot be used.

The most troublesome nostril tube intubation is very dependent on the sensation of the hand, and the nurse needs to rely on the feel of the hand to feel the patient's abdomen to determine the intubation. And through the three layers of gloves, this vibration is extremely weak or even disappears, and there is no way to judge it at all.

At the same time, under normal circumstances, whether the nostril cannula can be inserted in place is mainly judged by the stethoscope, and now without the help of the stethoscope, Wang Bingbing is blind.
