An example of a plateau pressure, checked after an end inspiratory pause when inspiratory flow has reached zero. The plateau pressure is 30 cm H2O, in a volume control mode with a set 420 mL (6 mL/kg PBW) tidal volume. The driving pressure is 15 cm H2O (plateau pressure of 30 cm H2O - PEEP of 15 cm H2O). The driving pressure is related to the static compliance of the respiratory system (CRS) by CRS = Tidal Volume/Driving Pressure. In this patient the CRS is low at 28 mL/cm H2O.
