This has to start from the protective mechanism of the respiratory tract, although the airway and the entrance to the esophagus are located in the pharynx and the distance is very close, but even if the awake state of the adult vomiting, will rarely be vomited to block the airway caused by asphyxiation, this is because of the laryngeal muscles and the epiglottis cartilage and other structures of the synergy of the work of the epiglottis in the vomiting will be blocking the airway to keep the foreign body outside, even if there is a small number of leakage, the airway will also be a reflex to “exclude the foreign body” through the violent coughing. Even if there is a small amount of leakage, the airway will “get rid of the foreign body” through a violent cough reflex. When drunk, the nerve receptors and the brain become extremely slow, these protective mechanisms are in a paralyzed state, once vomiting occurs, alcohol, food and stomach acid mixture into the airway, serious cases can be caused by asphyxiation, death, even if the fluke does not die, with a strong corrosive gastric acid will lead to upper respiratory tract damage and aspiration pneumonia. Like a variety of fancy persuade and to get drunk for fun friends pay attention, if you get people drunk after people have any accidents, you have to be legally responsible. If you are the unfortunate family member who has to help the drunken person return home, remember to keep an eye on the drunken person and try to make him/her lie on his/her side rather than on his/her back to minimize the possibility of aspiration during vomiting.
