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.
