Answer to Question 1

ANS: D
To describe what happens during expiration, we must know what baseline variable is in effect.

Answer to Question 2

ANS: A
If the ventilator controls flow, the flow and volume waveforms will remain consistent, but pres-sure will vary with changes in respiratory mechanics. Flow can be controlled directly using something as simple as a flow meter or as complex as a proportional solenoid valve. Flow can be controlled indirectly by controlling volume.
