D. Correct response: The spontaneous breathing trial (SBT) involves an integrated patient assessment during spontaneous breathing protocol with little or no ventilator assistance. The SBT can be accomplished by (1) using a T-piece (Briggs adaptor), (2) using a low level of CPAP (5 cm H2O), or (3) a low level of PSV (5 to 7 cm H2O) for at least 30 minutes, but no longer than 120 minutes.

Answer to Question 2

ANS: B
A. Incorrect response: See explanation B.
B Correct response: Multiplying the PTP/MIP by the inspiratory time fraction (Ti/Ttotal), that is,

The PTI is a useful predictor of ventilatory muscle fatigue.
