Can an endotracheal tube with a steel ring be inserted through the nose?

Yes. According to the query of the Acme business network that the tracheal tube with a steel ring can be inserted through the nose, there is no harm, tracheal intubation is the endotracheal tube (ETT, single-use, plastic tube with a sleeve) inserted into the trachea through the mouth or nose, the end of the catheter is placed in the middle part of the trachea, so as to provide a smooth airway for pulmonary ventilation. A tracheal tube is a medical device that is inserted into the patient's trachea to create a temporary artificial respiratory pathway for the patient, especially for patients who are unable to breathe on their own.
