During volume-assured pressure-supported ventilation, the breath will be pressure-limited under what conditions?

a. The delivered tidal volume (VT) is greater than the preset minimum VT.
b. The patient's lung or thoracic compliance decreases from the baseline.
c. The delivered VT is less than the preset minimum VT.
d. The patient's Raw increases from baseline.

ANS: A
If delivered tidal volume is greater than the preset minimum tidal volume, the breath becomes a pressure-supported breath.
