Besides that, the reservoir bag, mask, oxygen tube, and safety valve are all important components of it.
The patient already has a mask and oxygen tube on their face.
Lu Xin quickly unplugged the oxygen tube connected to the mask, attached the exhalation valve to the mask, and then connected the oxygen tube to the intake valve of the manual resuscitator bag.
The patient, on the verge of shock, had very weak breathing. The assembled manual resuscitator started working to provide artificial ventilation to the patient.
Lu Xin used one hand to fix the patient’s mask in place to prevent excessive gaps from forming that could allow air to escape, significantly reducing the effectiveness of ventilation. With the other hand, she grasped the bag, performing a press-and-release action. Each ti she pressed, the oxygen in the bag passed through the valve into the patient’s nasal and oral cavity, delivering air to the patient’s lungs, equivalent to the patient’s inhalation. Releasing it worked oppositely, as an exhalation.
At this ti, it was essential to be extrely cautious. This patient wasn’t in cardiac arrest; they had their own spontaneous breathing—though weak, it was undeniable that they hadn’t lost consciousness.
dical personnel need to squeeze the bag according to the patient’s breathing rate to avoid a conflict between artificial ventilation and the patient’s breathing frequency.
Lu Xin found it sowhat challenging holding the manual resuscitator.
It wasn’t because she hadn’t done it before and felt unfamiliar with the operation but because the dical student beside her seed very different, demanding higher standards in dical procedures than any doctor she had encountered before.
"No, your squeezing speed is about 0.5 seconds faster than her breathing; it will affect her breathing," Xie Wanying said to her.
What does a 0.5 second an? Could the impact be significant? Lu Xin blinked rapidly, both hands slightly at a loss, unsure of what to do.
Seeing this, Xie Wanying imdiately reached over to help her. While helping her squeeze the bag, she taught her to follow the rhythm: "One, two, one, two, one, two, like this."
Following the rhythm chanted by Xie Wanying, Lu Xin’s hands gradually aligned with the patient’s breathing frequency.
Xiao Shugang and Shang Siling looked on from the side, increasingly realizing that this little dical student cousin of theirs was: very steady.
Doctors value steadiness the most; the steadier the doctor, the more confidence they can instill in patients and their families.
Before long, Lu Xin discovered how magical that 0.5 second was.
Underneath the mask, the patient’s lip color, previously severely cyanotic, was slowly lightening, and the patient’s hypoxic state was clearly improving.
After being in clinical practice for several years, Lu Xin found this to be the first ti she’d encountered such a situation, feeling like she was witnessing a miracle unfold. She never thought a commonly used manual resuscitator could have such a significant impact.
From what she knew, most of the ti in clinical settings, people used this device to maintain the vital signs of critical patients during transportation as a substitute for a ventilator. Thinking of using it to improve the patient’s condition was out of the question. When used on patients with cardiac arrest, it’s to replace mouth-to-mouth during CPR. The critical role arises from CPR, not this device.
In conclusion, the device’s composition and principle are too simple, leading no one to expect miraculous effects from it. It can only be said that one should not underestimate any clinical tool, for even if a tool appears simple in principle and operation and is looked down upon as crude, its prolonged use without being phased out in clinical practice proves its reason for existence.
