Answer to Question 1

ANS: B
In the presence of dynamic airways obstruction, the application of PEEP offsets the effect of auto-PEEP on missed triggering.

Answer to Question 2

ANS: A
Flow asynchrony can be greatly improved in volume ventilation by increasing peak flow and de-creasing inspiratory time. In pressure ventilation, flow asynchrony can be corrected by adjusting rise time.
