A physician has selected a pressure support protocol to wean a patient off ventilatory support. Which of the following pressure levels would you recommend to begin the weaning process?
 
  a. Pressure sufficient to obtain a VT of 3 to 5 ml/kg of predicted body weight (PBW)
  b. Pressure sufficient to overcome the im-posed workload
  c. Pressure sufficient to obtain a VT of 4 to 8 ml/kg PBW
  d. Pressure equal to 30 of the vol-ume-cycled peak inspiratory pressure

Question 2

What are some advantages of mandatory minute ventilation (MMV) as a weaning tool?
 
  1. It provides greater control over PaCO2 than intermittent mandatory ventilation does.
  2. It prevents acidemia with acute hypoventilation.
  3. It eliminates concerns over depressant drugs.
  4. It ensures an efficient pattern of ventilation.
  a. 2 and 4 only
  b. 1, 2, and 3 only
  c. 3 and 4 only
