"I have to call someone to come and help." Ning Yunxi flipped through the instructions and said, "I'm afraid I can't repair it well, and I need someone to help."

Hearing her words, the director of the respiratory department thought he had hallucinated: "You can practice!"

"I can try it." Ning Yunxi said professionally, "mainly, in terms of hands-on ability, there is definitely not as good as front-line professionals. Bad parts need to be replaced by other things."

The director of the respiratory department understood it. She could see what was wrong with this thing. He was so excited that he said to her: "If we need our assistance, please just open your voice, Teacher Ning."

"I'll make a call first." Ning Yunxi called the hospital.

The phone number was called. Ning Yunxi first called the second son Meng Chenyi and then to her husband.

Not long after, reinforcements from both sides arrived. Meng Chenyi brought a few classmates to the other side. On the other side, Meng Chenhao received a call from his wife to help and discussed with Cao Defeng and others. When it came to save lives, the army was obliged to send a deputy chief of the technical department who was not on duty to bring a few soldiers to the hospital with the things his wife wanted.

Ning Yunxi looked at the arrival of reinforcements. Since they were not engaged in medical device research, they didn't understand what a ventilator was. Ning Yunxi first briefly introduced to the group of people: "The principle of the ventilator is this: the air source passes through the air oxygen mixer, then to the host, and then connects the humidifier here, and finally connects an external pipeline to supply air to the patient. Why is it air oxygen mixed? Because pure oxygen exceeds 41% concentration, people will get oxygen poisoned. Therefore, it is not a high concentration of pure oxygen is good for the human body. It is best to have the best composition of the air that people usually breathe, so a humidification device should be added. The most important thing is this host, the purpose of the host is to use a certain amount of pressure to transport the gas into the patient's lungs."

The troops and people from the college were listening to Ning Yunxi's speech, and the director of the respiratory department standing beside him was listening like several doctors. The doctors were surprised, thinking that a math teacher actually knew the principles of ventilators better than their doctors.

Ning Yunxi continued: "Patients who use ventilators generally have weak ventilation function and cannot breathe actively, which is manifested in weak chest expansion movements, which involve symptoms such as muscle weakness and deterioration in elderly people. It cannot replace the function of lung ventilation. Therefore, if the lungs are infected with a large amount of lung ventilation, it is useless to use ventilators alone. ECM technology, i.e., external membrane pulmonary oxygen and."

Chi! The sound of the breathing director pumping.

Meng Chenyi and the others heard it and knew very well what this meant. It meant that the doctors present were amazed that Teacher Ning's knowledge of medicine had surpassed their doctors themselves.

It’s no wonder that the director of the respiratory department was surprised to get exhausted. As Ning Yunxi said, ventilators have their defects. As for the application of ecmo for emergency aid in critically ill patients, foreign countries are now in the initial stage, let alone domestic ones. Even ventilators can’t handle it.

Teacher Ning is so admirable. Everyone knows the most cutting-edge medical research. Several respiratory experts and doctors thought with emotion. What’s even more terrifying is that their doctor cannot repair ventilators, but Teacher Ning can!
