b. 15-20 mm Hg
c. 20-25 mm Hg
d. 25-30 mm Hg

Question 2

The respiratory therapist is monitoring the cuff pressure of a tracheostomy tube inserted in a pa-tient who is receiving mechanical ventilation.

Answer to Question 1

ANS: C
Intracuff pressures should not exceed 20-25 mm Hg (27-34 cm H2O).

Answer to Question 2

ANS: B
The measured intracuff pressure is more than the acceptable range of pressure. Some air from the cuff should be released to bring the cuff pressure down to below 34 cm H2O.
