Which of the following ventilator strategies would you consider as a good alternative to T tube trials when using a rapid weaning protocol?
 
  1. Continuous positive airway pressure (CPAP) with flow-by (flow triggering)
  2. Low-level pressure-supported ventilation (PSV)
  3. Intermittent mandatory ventilation
  a. 2 and 3 only
  b. 1 and 2 only
  c. 1, 2, and 3
  d. 1 and 3 only

Question 2

Advantages of adding continuous positive airway pressure (CPAP) to T tube weaning include which of the following?
 
  1. Improved blood oxygenation
  2. Decreased work of breathing
  3. Compensation for auto-PEEP
  4. Faster weaning or extubation
  a. 1 and 3 only
  b. 1, 2, and 3 only
  c. 3 and 4 only
  d. 2, 3, and 4 only

Answer to Question 1

ANS: B
Rather than using a T tube trial, some clinicians prefer to maintain the patient attached to the ventilator with zero PSV and zero CPAP.

Answer to Question 2

ANS: B
CPAP has the advantage of maintaining lung volume during the weaning phase and thus of im-proving the patient's oxygenation status. Minimal levels of CPAP may be useful in reducing work of breathing and compensating for auto-PEEP, particularly in patients with obstructive lung disease.
