In ARDS management, what is a typical plateau pressure goal?

Explanation:
Plateau pressure is the pressure inside the alveoli during a brief inspiratory hold when there is no airflow, and it reflects the distending pressure the lungs actually experience. In ARDS, the goal is lung-protective ventilation, which means keeping this plateau pressure at about 30 cm H2O or lower to minimize alveolar overdistension and ventilator-induced lung injury. To achieve this, use a low tidal volume (around 6 mL/kg predicted body weight) and adjust PEEP to maintain oxygenation without pushing the plateau pressure above 30 cm H2O. If plateau pressure remains higher than 30 cm H2O, further reduce tidal volume and reassess ventilation strategy, possibly with adjuncts like recruitment maneuvers or prone positioning as appropriate.
