   It’s just—

   "Old antique." Zhang Huayao ranted wildly.

  What kind of laryngoscope is an antique laryngoscope? It's an indirect laryngoscope. It belongs to the laryngoscope structure that was invented almost at the beginning. The slender metal strip can penetrate the connected small mirror into the end of the patient's mouth, allowing the doctor to observe the patient's larynx through the mirror image. At this time, what the doctor sees in the mirror is opposite to the actual internal structure of the patient's body, so it is called an indirect laryngoscope.

  This thing is now used for general examinations in ENT departments, and it is very cost-effective to use it for general examinations for patients. An indirect laryngoscopy costs more than ten yuan, which is cheap, unlike other laryngoscopy, which costs hundreds of dollars. However, as a first aid, this old antique is useless.

  What the doctor needs at least is a direct laryngoscope, not a video laryngoscope. One of the biggest functions of direct laryngoscopy is to help doctors insert foreign body forceps into the trachea to remove foreign bodies.

   Zhang Huayao picked up this indirect laryngoscope, exhaled and tried it out.

   A woman as skilled as a doctor can hardly cook without rice.

   "I'll look for it again." Lin Liqiong turned around and decided to do what she could do.

   Seeing this, the nurse ran with her to find first aid equipment.

   Several doctors at the scene looked back at the indirect laryngoscope.

  When an otolaryngologist uses an indirect laryngoscope, a forehead reflector will be worn on the forehead, so that a concave mirror can condense light, and then a light source can be added, so that it can more clearly illuminate the deeper parts of the patient's mouth.

  In the small box, Zhang Huayao turned over and over again, only one indirect laryngoscope and nothing else. Forget it, let's use this guy to take a look at the throat of the child.

   The conditions are extremely simple, but Zhang Huayao wanted to scold people, and shouted: "Can't you bring an ECG monitor?"

  The child is in such a situation, and his heart stops at any time. ECG monitors must be on, breathing air bags, defibrillators, these can be brought quickly.

   was yelled by the boss. The nurse turned around to pull the ECG monitor and other rescue equipment over.

   "Senior brother, are you tired? I'll take care of you." Xie Wanying said, rolling up her sleeves.

   Cao Yong is doing chest shocks to the patient all the way. Don't underestimate the child's small body. It seems that it doesn't take much effort to do this. However, medical operations are all demanding. For example, chest impact, if the force is too much, it will easily damage the diaphragm, causing diaphragm rupture, diaphragmatic hernia that endangers the patient's life, and children are fragile, and they will accidentally press the short rib to rupture the spleen and liver, etc. These are bound to require doctors to control their strength at hand and operate as accurately as possible. As a result, the physical demands on the doctor are very high.

   "No." Cao Yong directly refused her proposal to replace him, showing that he was not tired. Moreover, he knew that it was more important for her to help Zhang Huayao determine where the cotton was inserted in the airway of the child.

  Senior Brother Cao seemed to have a lot of energy, Xie Wanying was relieved, and turned around to turn on a flashlight to help Teacher Zhang look inside the patient's mouth.

   The indirect laryngoscope held by Zhang Huayao was inserted into the mouth of the child.

   Such a simple condition is a test of the doctor's eyesight.

   Thank you for your support! ! ! Good night dears~
