Answer to Question 1

ANS: B
Physiological effects of volume-assured pressure-supported ventilation include improved pa-tient-ventilator synchrony and reduced pressure-time product, which is an indicator of decreased work of breathing.

Answer to Question 2

ANS: A
Pressure-supported ventilation with a volume guarantee is the goal of volume-assured pres-sure-supported ventilation.
