Answer to Question 1

ANS: D
If the ventilator controls volume, the volume and flow waveforms will remain consistent, but pressure will vary with changes in respiratory mechanics. To qualify as a true volume controller, a ventilator must measure volume and use this signal to control the volume waveform.

Answer to Question 2

ANS: D
There are only three variables in the equation of motion that a ventilator can control: pressure, volume, and flow.
