Question

Quizplus · Accepted Answer

The purpose of a cuff on an artificial tracheal airway is to seal off and protect the lower airway. This helps to prevent aspiration and also helps to maintain positive pressure ventilation.

Answer: B
 
The cuff also helps to stabilize the tube and prevent its movement, which can be important to prevent dislodgement or displacement of the airway.

Answer: C
 
While a cuff can provide some indication of tube position via radiograph, this is not the primary purpose of the cuff. Other methods, such as capnography, are more reliable for determining tube placement.

Answer: D
 
While the cuff may be used to help clinicians determine the depth of tube insertion, this is not its primary purpose. Other methods, such as measuring the distance from the nostril or lip to the insertion point, are more reliable for determining proper tube depth.
