  a. 5; 35
  b. 10; 30
  c. 12; 40
  d. 15; 35

Answer to Question 1

ANS: D
The low pressure alarm should be set 5-10 cm H2O below the PIP, and the high pressure alarm should be set about 10 cm H2O above the PIP. Therefore, with a PIP of 25 cm H2O, the low pressure alarm should be set at 15-20 cm H2O and the high pressure alarm at 35 cm H2O.

Answer to Question 2

ANS: C
A high pressure alarm may also be triggered when a patient actively breathes out of synchrony with the ventilator. The PIP rises if the patient actively exhales while the ventilator is in the in-spiratory phase, and this can activate the high pressure alarm.
