The flow waveform pattern that provides the shortest inspiratory time (TI) of all the available flow patterns with an equivalent peak flow rate setting is which of the following?
 
  a. Sine
  b. Constant
  c. Ascending ramp
  d. Descending ramp

Question 2

Slow flow rates will cause which of the following to occur?
 
  a. Poor gas exchange
  b. Increase peak pressures
  c. Shorten expiratory time
  d. Decrease mean airway pressure

Answer to Question 1

ANS: B
Generally, a constant flow pattern provides the shortest inspiratory time (TI) of all the available flow patterns with an equivalent peak flow rate setting.

Answer to Question 2

ANS: C
Slower flows may reduce peak pressures, improve gas distribution, and increase at the expense of increasing inspiratory time (TI). Unfortunately, shorter expiratory time (TE) can lead to air trap-ping, while using a longer TI may cause cardiovascular side effects.
