Repeated connecting and disconnecting of a cuff pressure manometer to the pilot tube of a cuffed tracheal airway will do which of the following?
 
  a. Increase cuff pressure.
  b. Not affect cuff pressure.
  c. Decrease cuff pressure.
  d. Rupture the cuff.

Question 2

Which of the following is false about cuff inflation techniques (MOV = minimal occluding vol-ume; MLT = minimal leak technique)?
 
  a. The MLT approach negates the need for pressure monitoring.
  b. The MLT allows a small leak at peak or end of inspiration.
  c. At MOV, air leakage around the tube cuff should cease.
  d. With MLT, secretions tend to be blown upward during inflation.

Answer to Question 1

ANS: C
Attaching the measurement system to the pilot tube evacuates some volume from the cuff (and lowers its pressure). For this reason, you should always adjust the pressure to the desired level, never just measure it.

Answer to Question 2

ANS: A
Cuff pressure measurements should be done regularly to maintain the cuff pressure in the safe range to avoid tracheal wall injury and minimize risk of aspiration of oral secretions.
