A physician asks you to assess the upper airway function of a patient with a fenestrated trache-ostomy tube. How should this be accomplished?
a. Replace the inner cannula, plug the proxi-mal opening, and inflate the cuff.
b. Remove the inner cannula, plug the prox-imal opening, and deflate the cuff.
c. Remove the inner cannula, plug the prox-imal opening, and inflate the cuff.
d. Replace the inner cannula, plug the proxi-mal opening, and deflate the cuff.
ANS: B
Removal of the inner cannula opens the fenestration allowing air to pass into the upper airway. Capping or placing a peaking valve on the proximal opening of the tube's outer cannula, accom-panied by deflation of the cuff, allows for assessment of upper airway function.
