Question 2

An 835-g newborn is receiving HFOV with the following settings: MAP = 10 cm H2O; FIO2 = 0.6; frequency = 10 Hz; amplitude (P) = 20 cm H2O.

The ABG values are: pH = 7.35, PaCO2 = 40 mm Hg, PaO2 = 40 mm Hg. Based on these data, which of the following is the most appropriate action?

Answer to Question 1

ANS: B
In the APRV mode, the Phigh is considered the baseline pressure.

Answer to Question 2

ANS: B
Increasing the MAP will improve the patient's oxygenation status. Oxygenation also can be al-tered by changing the FIO2.
