Answer to Question 1

ANS: D
The Bird Mark 7 is a pneumatically powered ventilator that will pressure-cycle during intermit-tent positive-pressure breathing therapy. If used for short-term mechanical ventilation, it could be time-cycled.

Answer to Question 2

ANS: C
Regardless of the manufacturer, all intermittent positive-pressure breathing machines require a 45-psig to 55-psig gas pressure source, such as a compressed gas cylinder, a bulk air or oxygen system, or an air compressor.
