In addition, oxygen storage bags, masks, oxygen tubes and safety valves are all important components.
The patient already has a mask and oxygen tube on his face.
Lu Xin quickly unplugged the oxygen tube connected to the mask, connected the exhalation valve to the mask, and connected the oxygen tube to the air inlet valve behind the simple respirator bag.
The patient was on the verge of shock and his breathing was very weak. The simple respirator assembled on site started to work and gave the patient artificial ventilation.
Lu Xin put one hand on the patient's mask to fix it, to prevent the mask from moving and creating a large gap, which would allow the gas to escape from the mask. This would greatly reduce the ventilation effect. With the other hand, she held the balloon part and pressed and released the balloon. With each press, the oxygen in the balloon would enter the patient's nose and mouth through the air valve, and supply air to the patient's lungs, which is equivalent to the patient's inhalation. When released, it is the opposite, exhalation.
At this time, we must pay special attention to one thing. This patient is not in cardiac arrest. He has his own spontaneous breathing, although it is weak, but it is undeniable that he has not lost consciousness.
Medical staff need to press and squeeze the balloon according to the patient's respiratory rate to avoid conflict between artificial assisted ventilation and the patient's respiratory rate.
Lu Xin felt a little bit difficult holding the simple respirator.
It was not because she had never done this kind of work and was unfamiliar with the operations, but because the medical student next to her was very different. His requirements for medical operations were stricter and higher than any doctor she had met.

"No, your massaging speed is about 0.5 seconds faster than her breathing, which will affect her breathing." Xie Wanying said to her.
What does 0.5 seconds mean? Will the impact be significant? Lu Xin blinked fiercely, her hands looking a little helpless, not knowing what to do.
Seeing this, Xie Wanying immediately reached out to help her. She helped her hold the air bag and taught her how to read the rhythm: "One, two, one, two, one, two, like this."
Following the rhythm of Xie Wanying's recitation, Lu Xin's hands gradually found the patient's breathing rate.
Xiao Shugang and Shang Siling were watching from the side, and the more they watched, the more they realized that this little cousin who was studying medicine was: very stable.
The most important thing for a doctor is stability. The more stable a doctor is, the more peace of mind he can give to patients and their families.
Soon, Lu Xin discovered that this 0.5 seconds was amazing.
The patient's lip color under the mask is gradually becoming lighter from the previous severe cyanosis, and the patient's hypoxia condition is significantly improving.
After working in the clinic for several years, this was the first time Lu Xin encountered such a situation. She felt like she was watching a miracle. She never thought that a commonly used simple ventilator could play such a big role.
As far as she knows, most of the time when people use this thing in clinical practice, it can maintain the patient's vital signs when it is used to replace the ventilator to transfer critically ill patients. It is a no-brainer to use it to improve the patient's condition. As for using it to replace artificial respiration for patients with cardiac arrest, the patient's heart is in trouble, not the breathing, and it is CPR that plays a key role, not this.
In short, the composition and principle of this thing are too simple, so no one expects it to have miraculous effects. All I can say is that you should not underestimate any clinical tool, even if the principle and operation of the tool seem to be simple and despised by people, it has been used in clinical practice for many years without being eliminated, and there is definitely a reason for its existence.
