The purpose of the Venturi-type air amplifier on the CareFusion 3100A is to do which of the following?
 
  a. Provide gas for bias flow
  b. Add gas to increase the volume delivered
  c. Cool the electrical coil that moves the pis-ton
  d. Prevent the square wave driver from overheating

Question 2

Answer to Question 1

ANS: C
The function of the Venturi-type air amplifier is to introduce cooling air around the electrical coil.

Answer to Question 2

ANS: C
An increase in  inspiratory time would cause more time to be spent in the inspiratory phase, so the symmetry of the waveform would be altered. The change to  inspiratory time would also cause an increase in airway pressure. This change should be readjusted by using the power con-trol.
