Foreign bodies have entered the airway. How to give first aid?

Sometimes when you talk while eating, you will choke if you are not careful, because talking while eating can easily lead to food entering the trachea. If it is suffocation, it will be better, and some serious ones will even block the airway. At this time, it is even more dangerous. If the foreign body completely blocks the airway, it will be life-threatening for more than five minutes. In the past two years, there have been frequent reports that children suffocate because of eating jelly. I didn't know what to do when I saw this before, but now I know what to do after studying medicine.

The simplest and most practical method is Heimlich first aid, which was invented by an American doctor named Heimlich in 1974. At that time, he successfully saved the life of a patient whose airway was blocked by food, so this first aid method was named after him.

Heimlich's first aid method is simple abdominal granules. The rescuer stood behind the patient and put his hands around the patient's abdomen, suddenly producing a huge particle force on the abdomen. The residual gas in the lungs is used to generate a huge impact force on foreign bodies blocked in the airway. Like a blocked pipe, we give it a huge airflow at one end to wash it away. If once is not enough, we can do it several times. It should be noted that you should control your strength when you meet children.

If Heimlich first aid doesn't work and the foreign body card is located closer to the airway. Tracheotomy can be considered, that is, the cricoid cartilage is cut 2 ~ 3 cm below the Adam's apple with a knife or pen, so that air can directly enter the lungs. Of course, this requires a certain medical foundation to dare to do it, and most people dare not sit.
