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?
a. Increase the frequency.
b. Increase the MAP.
c. Decrease the amplitude.
d. Decrease the bias flow.


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