Answer to Question 1

ANS: A
The operation of proportional assist ventilation is based on the equation of motion. The amount of pressure generated by the patient's own respiratory muscles is used as an index of inspiration effort.

Answer to Question 2

ANS: D
Volume-support ventilation on the Maquet Servo 300 is purely assist mode and is basically a form of pressure-support ventilation except that the volume delivery is targeted over several breaths. Mandatory minute ventilation is a closed-loop form of volume-targeted or pres-sure-targeted ventilation used in patients who can perform part of the work of breathing and are progressing toward weaning from mechanical ventilation. Proportional assist ventilation is a method of assisting spontaneous ventilation in which the practitioner adjusts the amount of the work of breathing assumed by the ventilator.
