Chapter 1550 [1550] Different Second Difference
In addition, oxygen storage bags, masks, oxygen tubes, and safety valves are all important components of it.
A mask and oxygen tubing are already 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 intake valve behind the simple respirator balloon.
Patients on the verge of shock have very weak breathing. The simple respirator assembled on site started to work, and artificially ventilated the patient.
Lu Xin pressed the patient's mask with one hand to fix it, so as to avoid excessive gaps caused by the movement of the mask, allowing the gas to escape from the mask. This will greatly reduce the ventilation effect. With the other hand, she held the balloon part, and pressed and released the balloon. Each time you press, the oxygen in the balloon will enter the patient's nose and mouth through the air valve, and air will be supplied to the patient's lungs, which is equivalent to the patient's inhalation action. When it is released, it is the opposite, it is an exhalation.
At this time, we must be very careful. This patient is not a patient in cardiac arrest, and has his own spontaneous breathing. Although it is weak, it is undeniable that his consciousness has not been lost.
Medical personnel need to press and pinch the balloon according to the patient's breathing rate to avoid conflicts between artificial assisted ventilation and the patient's breathing rate.
Lu Xin felt a bit difficult holding the simple respirator.
It's not because she has never done this kind of work and is unfamiliar with the operation, but the medical student next to her is very different, and her requirements for medical operations are stricter and higher than any doctor she has ever met.
"No, your pinching 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 were a little at a loss, she didn't know what to do.
Seeing this, Xie Wanying immediately reached out 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 reading, Lu Xin's hand gradually found the patient's breathing rate.
Xiao Shugang and Shang Siling watched from the side, and the more he looked, the more he found that this little cousin who studied medicine was: so stable.
Doctors pay most attention to stability, and a more stable doctor can make patients and their families feel the greatest peace of mind.
Soon, Lu Xin discovered that this 0.5 seconds is amazing.
The lip color of the patient under the mask gradually faded from the severe cyanosis before, and the patient's hypoxic state is obviously improving.
After entering the clinic for several years, this is the first time that Lu Xin has encountered such a situation, and it feels like watching a miracle unfold. She never imagined that a commonly used improvised respirator could do so much.
As far as she knows, most of the time people use this thing in clinical practice, and it can maintain the vital signs of patients when they are used instead of ventilators to transfer critically ill patients. It is not necessary to think about using it to improve the patient's condition. As for use on patients with cardiac arrest, use it instead of artificial respiration. The patient had a cardiac accident rather than a respiratory accident, and it was CPR that played a key role, and not it.
All in all, the composition and principle of this thing are too simple, so no one expects it to have miraculous effects. It can only be said not to underestimate any clinical tool, even if the principle seems to be easy to operate, the tool is despised as crude, and there is definitely a reason for its existence in clinical use for many years without being eliminated.
