Answer to Question 1

ANS: C
In most patients with ARDS, PEEP levels below 20 cm H2O are generally preferred. Levels of PEEP greater than 20 cm H2O should not be routinely used unless the benefits of higher levels of PEEP are supported by objective end points, such as improved lung compliance or optimal alve-olar recruitment.

Answer to Question 2

ANS: D
The clinical aim of APRV is to increase the mean airway pressure to allow recruitment of alveoli while allowing the patient to spontaneously breathe.
