To measure plateau pressure, inspiration should be held for how many seconds?
a. 1-2
b. 2-3
c. 3-4

Plateau pressure requires the establishment of a period of no-flow for 1-2 seconds to allow pres-sure equilibration by the redistribution of the tidal volume and stress relaxation. This maneuver increases inspiratory time and if held longer than 2 seconds may cause barotrauma.
