Patency of the tracheostomy tube should be verified by which of the following procedures
I.Positive end-tidal CO₂
II.Measuring exhaled tidal volume
III.Passing a suction catheter
IV.Bag-mask ventilation

Question

Quizplus · Accepted Answer

Positive end-tidal CO₂ (I) can be used to confirm that air is passing through the tracheostomy tube and being exhaled. Passing a suction catheter (III) can also assess for any obstructions or secretions in the tube. Measuring exhaled tidal volume (II) and bag-mask ventilation (IV) are not direct methods of verifying tracheostomy tube patency.
