However, the establishment of the artificial airway also affects the normal physiological functions of the body to a certain extent, and particularly, after a tracheal catheter is inserted into the airway of a patient, the swallowing of the patient is limited, and oral secretion and gastroesophageal reflux are blocked by the air sac and are retained above the air sac to form retentates on the air sac. If the artificial airway air bag is not tightly closed, the retentate on the air bag leaks to the lower respiratory tract along the air bag wall, so that the patient inhales by mistake and the ventilator-associated pneumonia is caused. If the pressure of the air bag is set to be too high in order to improve the air bag tightness, the air bag can obviously press mucous membrane tissues of the air passage to cause mucous membrane ischemia and necrosis, then the air passage is narrowed or even perforated to form the tracheoesophageal fistula.
