The Importance of Plateau Pressure

  • Alveolar overdistention is a precursor to the development of acute lung injury (ALI)
  • Plateau pressure is a measurement of alveolar overdistention, and is the pressure equilibration between the airways and the alveoli
  • Plateau pressure is measured by using an inspiratory hold (for at least 3 seconds) at the end of inspiration
  • Based on available data, you want to maintain the plateau pressure < 30 cm H2O
  • Remember that patients should be heavily sedated to obtain this measurement - any patient-ventilator asynchrony may provide inaccurate information
