Intubation mainly refers to the insertion of a catheter into the human body through the surface of the body or the body’s orifices, which is used to input or suction gas or liquid, and common intubation includes tracheal intubation, gastric intubation, etc. These intubations have their own characteristics. These intubations have their own, for example, tracheal intubation is a suction tube inserted into the human trachea through the pharyngeal cavity and the voice box for ventilation, which is suitable for patients who are unconscious, have no ability to protect the airway, or patients who are in severe shock and other conditions.
