What is the purpose of a tracheostomy tube obturator?

Question

Quizplus · Accepted Answer

The tracheostomy tube obturator is used during insertion to minimize trauma to the tracheal mucosa. It is a blunt-tipped rod that is inserted through the tracheostomy tube to guide it into the trachea. Once the tracheostomy tube is in place, the obturator is removed.

Answer: B
 While a tracheostomy tube obturator is used during insertion, its primary purpose is to provide a patent airway should the tube become obstructed. In an emergency situation, the obturator can be reinserted into the tracheostomy tube to help maintain an open airway until the obstruction is cleared.

Answer: C and D
 Neither of these choices describe the purpose of a tracheostomy tube obturator. The proper tube position is determined by clinical assessment and radiograph, not by the obturator. The ability to inflate and deflate the tube cuff is not related to the obturator, but rather to the tube itself.
