Answer to Question 1

ANS: C
One of the two methods for triggering to inspiratory positive airway pressure breathing is vol-ume. When 6 mL of volume from patient effort is inhaled from the circuit, the ventilator will volume trigger to inspiratory positive airway pressure breathing.

Answer to Question 2

ANS: C
The BiPAP Vision has a system called Auto-Trak sensitivity that uses a combination of two mechanisms to identify and modify baseline values in response to leaks. These are expiratory flow rate and tidal volume adjustments.
