  a. Delivered tidal volume will decrease.
  b. Volume curve will end under the zero line.
  c. Inspiration will end prior to flow tapering to zero.
  d. Pressure curve will become concave on inspiration.

Question 2

An inadequate flow setting during volume ventilation will cause which of the following to oc-cur?
 
  a. The volume curve will drop below the zero baseline.
  b. The volume curve will not drop to the zero baseline.
  c. The exhaled flow will take longer to rise to the zero baseline.
  d. The pressure-time curve will appear con-cave during inspiration.

Answer to Question 1

ANS: A
When compliance is reduced during pressure ventilation the volume delivered will be reduced proportionally. The volume curve ending under the zero line is indicative of active exhalation. Inspiration ending prior to the flow tapering to zero is consistent with an increase in airway re-sistance. The pressure curve becoming concave on inspiration is consistent with inadequate flow.

Answer to Question 2

ANS: D
When the flow rate setting is inadequate, the pressure-time scalar takes a concave shape during inspiration. A volume curve dropping below baseline is indicative of active exhalation. A volume curve that ends above baseline indicates a leak. An exhaled flow curve that takes the entire ex-piratory time to rise back to zero baseline is indicative of increased airway resistance.
