In addition, storage bags, masks, oxygen tubes, and safety valves are all important parts of it.
There is already a mask and oxygen tube on the patient's 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 balloon of the simple respirator.
A patient on the verge of shock has very weak breathing. The simple respirator assembled on site started working to provide artificial ventilation to the patient.
Lu Xin pressed one hand on the patient's mask to fix it to prevent the mask from moving and creating too large a gap, allowing the gas to escape from the mask. This will greatly reduce the ventilation effect. She held the balloon part with her other hand and pressed and released the balloon. Each time you press it, the oxygen flowing in the balloon will enter the patient's nose and mouth through the air valve, supplying air to the patient's lungs, which is equivalent to the patient's inhalation action. When you let go, on the contrary, you exhale.
You must be very careful at this time. This patient was not a cardiac arrest patient. He was breathing on his own. Although it was weak, it was undeniable that his consciousness was still intact.
Medical staff need to press and hold the balloon according to the patient's respiratory rate to avoid conflicts between artificial assisted ventilation and the patient's respiratory rate.
Lu Xin felt a little bit of difficulty holding the simple respirator.
It wasn't that she had never done this kind of work before and the operation was unfamiliar to her, but that the medical student next to her was very different, and his requirements for medical operations were stricter and higher than any doctor she had ever encountered.
"No, your pressing speed is about 0.5 seconds faster than her breathing, which will affect her breathing." Xie Wanying said to her.
What is the concept of 0.5 seconds? Will the impact be huge? Lu Xin blinked fiercely, her hands slightly helpless as she didn't know what to do.
Seeing this, Xie Wanying immediately stretched out her hand to help her. Help her pinch the airbag and teach her to read the rhythm: "One, two, one, two, one, two, like this."
Following the rhythm of Xie Wanying's chanting, Lu Xin's hand gradually found the patient's breathing rate.
Xiao Shugang and Shang Siling watched from the side. The more they looked, the more they realized that this little cousin studying medicine was: so stable.
Doctors are most particular about stability. A more stable doctor can make appointments with patients and their families feel the greatest peace of mind.
Soon, Lu Xin discovered that this 0.5 seconds was amazing.
Under the mask, the patient's lip color gradually became lighter from the previous severe cyanosis, and the patient's hypoxic condition was significantly improved.
Several years after entering the clinic, this was the first time Lu Xin encountered such a situation. It felt like she was watching a miracle unfold. She never imagined that a commonly used simple respirator could play such a big role.
As far as she knows, most of the time in clinical practice, this thing is used to maintain the patient's vital signs when used instead of a ventilator to transfer critically ill patients. It is a no-brainer to use it to improve the patient's condition. As for its use in patients with cardiac arrest, it can be used instead of artificial respiration. The patient had a heart accident, not a respiratory one, and it was not CPR that played a key role.
All in all, 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 a tool whose principle seems to be easy to operate is despised as crude, it definitely has a reason for its existence after being used clinically for many years without being eliminated.
