Answer to Question 1

ANS: C
The scalar shows a pressure overshoot owing to the rapid flow rate at the very beginning of in-spiration. Adjusting the slope of the pressure and flow curves can change the rate of gas delivery at the very beginning of inspiration. This tapers the curves slightly until they reach their maximum value. Decreasing the pressure setting may alleviate the overshooting problem, but it does not provide the same level of assistance to the patient. Inspiratory time and volume are controlled by the patient in pressure-support ventilation and cannot be adjusted.

Answer to Question 2

ANS: C
During pressure-controlled ventilation, the delivery of the volume varies according to the charac-teristics of the lungs. Improving compliance makes it easier to deliver a volume with the same set pressure.
