Answer to Question 1

ANS: D
Other techniques that may be helpful in improving arterial O2 levels include the use of PCV with a prolonged inspiratory time, use of an inspiratory pause, inverse 1:E ratio ventilation, and prone positioning.

Answer to Question 2

ANS: D
Generally, PEEP is sustained at the set level until FiO2 is less than 0.5, and when PEEP is de-creased, it should be decreased in increments of 2 cm H2O no more frequently than approxi-mately every 6 to 8 hr.
