Explain the difference between ET intubation and a tracheostomy tube.
What will be an ideal response?
Endotracheal (ET) intubation is the placement of an ET tube inside the trachea through the mouth or nostril. ET intubation is a simpler procedure than tracheotomy-a surgical procedure that creates an airway opening by cutting into the trachea. Compared to an ET tube, a tracheostomy tube is much shorter and it provides closer access to the lower airways. It has a lower mechanical deadspace volume than an ET tube. It also ventilates the patient more efficiently and enhances secretion removal. In spite of many advantages of a tracheostomy tube, ET intubation is preferred as the initial means of establishing an artificial airway.
