Your patient is being ventilated with a common critical care ventilator using pressure support ventilation (flow cycled) with a nasal mask. A leak is present that is preventing the appropriate termination of the inspiratory cycle.
 
  What is the best response?
  a. Switch to volume control mode.
  b. Switch to time-cycled mode.
  c. Switch to nasal pillows.
  d. Switch to full-face mask.

Question 2

Which level of positive end-expiratory pressure (PEEP) is necessary to prevent rebreathing of carbon dioxide?
 
  a. 1 to 3 cm H2O
  b. 3 to 5 cm H2O
  c. 5 to 7 cm H2O
  d. 7 to 9 cm H2O

Answer to Question 1

ANS: B
Time-cycled (instead of flow-cycled), pressure-limited ventilation in the presence of air leaks markedly improves patient-ventilator synchrony and patient comfort.

Answer to Question 2

ANS: B
These reports suggest the use of 3 to 5 cm H2O PEEP or the use of a nonrebreathing valve to prevent rebreathing of carbon dioxide.
