The thing was lying on the velvet cloth in the box. It was well protected. A small mirror was attached to a thin metal strip. It looked a bit like a dental mirror, but much longer. So it was definitely not a dental mirror, but a laryngoscope.

It's just that——

"Old antique." Zhang Huayao complained wildly.

What kind of laryngoscope is this antique laryngoscope? It is an indirect laryngoscope. It is one of the earliest laryngoscope structures invented. The thin metal strip can connect the small mirror to the end of the patient's mouth, allowing the doctor to observe the patient's throat through the mirror. At this time, what the doctor sees in the mirror is the opposite of what he sees in the patient's actual body structure, so it is called an indirect laryngoscope.

This thing is now mostly used for routine examinations in the ENT department. It is very cost-saving to use it to perform routine examinations on patients. An indirect laryngoscopy costs only a dozen yuan, which is very cheap, unlike other laryngoscopy examinations, which can easily cost hundreds of yuan. However, as an emergency rescue, this antique is useless.

The doctor needs at least a direct laryngoscope, and it is also possible not to use a video laryngoscope. The biggest function of a direct laryngoscope is to help the doctor insert a foreign body forceps into the trachea to remove the foreign body.

Zhang Huayao picked up the indirect laryngoscope, exhaled, and tried it reluctantly.

Just like a doctor, a good cook cannot cook without rice.

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

...

...

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

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

When using an indirect laryngoscope, an otolaryngologist will wear a forehead reflector on his forehead. It is a concave mirror that can focus light and is equipped with a light source. This allows the deeper parts of the patient's mouth to be more clearly illuminated.

Zhang Huayao searched the small box again and found nothing but an indirect laryngoscope. Forget it, he would use this thing to check the condition of the child's throat.

The conditions were extremely rudimentary, but Zhang Huayao wanted to curse, and shouted: "Can't you bring an ECG monitor?"

The child is in this condition, his heart may stop at any time. An ECG monitor must be used, as well as a breathing bag and a defibrillator. If you can get them, get them now.

The boss yelled at her. The nurse turned around and went to get the ECG monitor and other rescue equipment.

"Brother, are you tired? I'll take you." Xie Wanying said as she rolled up her sleeves.

Cao Yong was doing chest thrusts on the child all the way. Don't underestimate the child's small body, as it seems that it doesn't take much effort to do this. However, all medical operations are subject to stringent conditions. For example, if the chest thrust is too strong, it will easily damage the diaphragm, causing diaphragmatic rupture and diaphragmatic hernia that endangers the patient's life. Children are fragile and may accidentally press the short ribs and break the spleen and liver. These will inevitably require doctors to control their hand strength and perform the operation as accurately as possible. In this way, the physical strength of the doctor is very high.

"No need." Cao Yong directly rejected her proposal to do it for him, indicating that he was not tired. Besides, he knew that it was more important for her to help Zhang Huayao determine the exact position of the cotton in the child's airway.

Senior Brother Cao seemed to have plenty of energy, so Xie Wanying felt relieved and turned around to hold a flashlight to help Teacher Zhang shine it into the child's mouth.

Zhang Huayao inserted the indirect laryngoscope into the child's mouth.

Such simple conditions are really a test of the doctor's vision.
