What is the maximum permissible plateau pressure (Pplat) according to the ARDS net protocol?

The maximum permissible plateau pressure (Pplat) according to the ARDSnet protocol is set to 30 cm H2O. This guideline is critical for managing patients with Acute Respiratory Distress Syndrome (ARDS) because elevated plateau pressures can lead to ventilator-induced lung injury. The ARDSnet protocol emphasizes protective lung strategies, which include low tidal volume ventilation and the limitation of plateau pressure to minimize adverse effects on lung function and potential complications from barotrauma.

Maintaining the plateau pressure at or below 30 cm H2O helps ensure adequate oxygenation while reducing the risk of further lung damage, facilitating better overall outcomes for patients suffering from this condition.
