Answer to Question 1

ANS: B
The ventilator must have alarms for circuit disconnect, loss of power, and battery failure if a bat-tery is present.

Answer to Question 2

ANS: D
Noninvasive positive-pressure ventilators should provide a mandatory rate of 30 breaths/min or less, inspiratory pressure of 30 cm H2O or less, positive end-expiratory pressure (PEEP or end-positive airway pressure EPAP) of 15 cm H2O or less, inspiratory flow of 180 L/min or less at 20 cm H2O, ideally an FiO2 from 0.21 to approximately 1.0, minimal rebreathing potential, and antiasphyxia capabilities.
