   took off his jacket and threw it aside, Zhang Huayao rolled up his sleeves and approached, and asked Cao Yong and Xie Wanying, "What's the situation?"

Hearing Teacher Zhang's voice, Xie Wanying, who was standing at the head of the bed and continued to examine the patient's mouth, raised her head and replied, "From the inside of the patient's mouth, it is preliminarily judged that the blockage is not in the patient's mouth, nor should it be in the throat. "

   Zhang Huayao stood beside her and listened to her report. He opened the patient's mouth and looked inside the patient's mouth. He asked, "Did you pat the back? Did you do the Heimlich method?"

  The Heimlich method is not a slap on the back, which is something that many people misunderstand. Dr. Heimlich, who invented the Heimlich method, has been engaged in academic debates between his abdominal thrusting method, the back-beating method and the chest thrusting method, arguing which method can save patients with airway obstruction better. Many foreign quarrels have attracted the attention of the whole society.

   To be more precise, the Heimlich method is the abdominal thrust method that Cao Yong demonstrated just now. Many countries recommend the first aid methods for airway obstruction to medical personnel in this order. First, they should use the back pat, five times on the back, and then the abdominal thrust method. If not, the chest thrust method is five times. Repeat this cycle until the patient's foreign body is expelled or the foreign body cannot be expelled. If the latter shows signs of the patient's unconsciousness and cardiac respiration, the urgent thing to do is not to remove the foreign body, but to perform cardiopulmonary resuscitation.

   Hearing that the two of them had tried all the above three methods to no effect, Zhang Huayao sighed in his heart: Both of them are the best medical students of the National Association, that's right, they are correctly implemented in accordance with the guidelines.

  The best doctor and medical student should do the most rational thing at a critical time. What is the most sensible thing to do? Follow medical guidelines.

   "Is there a bronchoscope? Is there a laryngoscope?" Zhang Huayao asked the same question as Xie Wanying.

   The nurse who ran to call him to save people, never expected the boss to say exactly the same thing as this female doctor, his tongue was about to be knotted, and he stammered: "I, I'll go to—"

   "Yes, the laryngoscope is here." Lin Liqiong answered loudly, running over with a small box in her hand.

   She is right, believing in Xie Wanying is equivalent to believing in a boss.

  The small black box was placed on the table next to it, and the lid was opened to reveal the laryngoscope equipment inside.

  Laryngoscopy and bronchoscopy are different. As can be seen from the name, the two have significantly different scopes of action. Laryngoscopy is mainly used to examine the larynx, and bronchoscopy is used to examine the bronchi. To be clear, the bronchi are not the trachea, the bronchi are the branches that branch off from the trachea. Why do I need to make this clear, because the laryngoscope can be inserted into the trachea for operation, but it cannot reach the bronchus. If the foreign body is blocked in the bronchus, only a bronchoscope can be used.

   Several doctors glanced at the laryngoscope equipment in the box. Zhang Huayao rolled his eyes on the spot: "What kind of laryngoscope are you looking for? Where did you get it?"

   In fact, Lin Liqiong, who was looking for a laryngoscope, didn't think much about it. The situation was urgent. Only when she saw a box with the words "Laryngoscope" written on it, she immediately brought it over to save people. It is not easy to find a laryngoscope for an ENT specialist in a dental department. Looking at it now, Lin Liqiong was dumbfounded.
