Compared with a volume-cycled strategy, what are some potential advantages of pres-sure-targeted ventilatory support?
1. Limit and control of peak airway pressures
2. Direct control over inspiratory time
3. Provision of a decelerating flow pattern
a. 1 and 2 only
b. 2 and 3 only
c. 1 and 3 only
d. 1, 2, and 3
ANS: C
Pressure-control ventilation is useful in limiting airway pressure and providing a decreasing (de-celerating) flow, which may improve gas distribution, patient comfort, and synchrony.
