Select the MOST CORRECT response.

1: Specific indications for high-frequency oscillatory ventilation (HFOV) in neonates includes all of the following, EXCEPT:: respiratory distress syndrome
meconium aspiration
persistent pulmonary hypertension
apnea of prematurity
2: The rationale for implementation of HFOV after failure of conventional ventilation includes which of the following?: decreased ventilator-induced lung injury
increased minute ventilation
increased FIO2
decreased mean airway pressure
3: Which of the following ventilators have the capability for HFOV?: SensorMedics 3100b
Drager Babylog
Infant Star 950
all of the above
4: The number of ribs visible on the chest radiograph is one parameter that is used to adjust which HFOV control?: bias flow
mean airway pressure
frequency
amplitude
5: Which HFOV control is adjusted in response to observation of the chest wiggle?: inspiratory time %
mean airway pressure
amplitude
frequency
6: Which HFOV control is similar to the tidal volume control on a conventional ventilator?: bias flow
inspiratory time %
amplitude
frequency
7: The initial frequency setting range for adults is:: 5-6 Hz
16-20 breaths/min
15-20 Hz
10-12 Hz
8: The PaCO2 for a patient ventilated with HFOV will be increased by making which adjustment(s)?: increasing the rate
increasing the amplitude
increasing inspiratory time %
all of the above
9: The PaO2 for a patient ventilated with HFOV will be increased by making which adjustment(s)?: increasing the mean airway pressure
increasing the amplitude
increasing inspiratory time %
all of the above
10: If the bias flow on an oscillatory ventilator is inadequate, which of the following will result?: inability to reach adjusted rate
inability to reach adjusted amplitude
inability to reach adjusted mean airway pressure
dampening of exhalation, with increased PaCO2
