And can timely suck out the endocrine or foreign matters in the trachea, prevent the foreign matters from entering the respiratory tract, keep the respiratory tract smooth, perform effective artificial or mechanical ventilation and prevent the hypoxia and carbon dioxide retention of patients. Whether the trachea cannula is timely or not is directly related to whether the rescue is successful or not, whether the patient can safely transport the trachea cannula or not, and the prognosis situation of the patient.

However, during the respiratory support of the tracheal intubation, oral secretion is obviously increased due to the stimulation of 1. Foreign matters, 2. In the prone position, gastric contents are easy to reflux, 3. Nasal drainage is obstructed, 4. Oral clearance is poor, so that the oropharynx is filled with liquid containing infectious substances; the blocking of the trachea cannula and the use of analgesic and sedative drugs lead the epiglottis not to cover the pharynx effectively, and the glottis cannot be closed normally, and most of the time, the liquid slowly passes through the glottis to form hidden aspiration; ventilator associated pneumonia is therefore inevitable.
