Answer to Question 1

ANS: B
When the cuff is deflated, the ventilator increases flow during exhalation to maintain the set PEEP because a leak is detected. PEEP impedes expiratory flow through the ventilator expirato-ry valve, so air flows through the larynx. By using a longer inspiratory time and PEEP, the addi-tive effect produces increased speaking time and improved speech quality.

Answer to Question 2

ANS: D
An external DC battery allows the ventilator to be mounted and used on a wheelchair or in a car. Use of an external DC battery enables longer operation, as needed, during transport.
