Answer to Question 1

ANS: C
The Crossvent requires a compressed gas source of 31 to 75 psi to ensure adequate gas flow to the patient. If the gas pressure drops below 31 psi, a low pressure alarm activates.

Answer to Question 2

ANS: C
The bilevel mode supplied by this ventilator is not a timed mode. It is a spontaneous mode only. Because there are no alarms, use of this ventilator on a patient who has apnea episodes is contra-indicated.
