  a. 5 to 10 cm H2O above the peak pressure
  b. 10 to 20 cm H2O above the peak pressure
  c. 10 to 12 cm H2O above the plateau pres-sure
  d. 10 to 15 cm H2O above the mean airway pressure

Question 2

  a. 1 only
  b. 1 and 2 only
  c. 1 and 3 only

Answer to Question 1

ANS: B
If the plateau pressure is less than 30 cm H2O, the high pressure limit can be adjusted to 10 to 20 cm H2O above the peak inspiratory pressure.

Answer to Question 2

ANS: C
Use of HMEs should be avoided in the care of patients with secretion problems and those with low body temperature (<32 C), high spontaneous minute ventilation (>10 L/min), or air leaks in which exhaled tidal volume is less than 70 of delivered tidal volume.
