Answer to Question 1

ANS: A
In a single-circuit ventilator, the gas enters the ventilator and goes directly to the patient.

Answer to Question 2

ANS: A
Flow resistors are used in positive expiratory pressure masks to combat atelectasis and aid in the removal of secretions. They are used less commonly in ventilator circuits. The Downs continuous positive airway pressure generator uses a threshold resistor to generate positive pressure. Modern ventilators use threshold resistors to generate expiratory pressure. Fluidic devices do not use flow resistors.
