Answer to Question 1

ANS: C
During pressure-controlled ventilation, the delivery of the volume varies according to the charac-teristics of the lungs. Worsening lung compliance is indicative of stiffening lungs. This would cause less volume to be delivered with the same set pressure.

Answer to Question 2

ANS: A
During volume-controlled ventilation, the peak inspiratory pressure generated by the delivery of the volume varies according to the characteristics of the lungs. Improving compliance makes it easier to deliver a volume, decreasing the pressure generated in the lungs.
