  Purpose

30% of ARDS patients ventilated according to NIH protocol presents morphological (CT) and functional (Stress Index>1) conditions of hyperinflation even with Plateau pressure (Pplat) < 30 cmH2O; values of Pplat lower than 26 cmH2O were associated with more a condition of more protective ventilation.

In patients at risk of hyperinflation, use of alternative techniques such as CO2-removal my allow the reduction of Tidal Volume (Vt) and Pplat.

Primary Outcome Measures:
  • pulmonary inflammatory mediator reduction [ Time Frame: within the first 72 hours after enrollment ]

Estimated Enrollment: 200
Study Start Date: April 2007
Study Completion Date: November 2008
Intervention Details:
    Procedure: protective ventilation with CO2 removal technique
    In ARDS patients, presenting a Pplat ≥ 26 cmH2O, Vt was lowered (reaching a Pplat < 26) with CO2-removal veno-venous pump-driven bypass support for 48 consecutive hours with a pH > 7,30 or at least 72 hours from the beginning of the extracorporeal treatment.
Detailed Description:
Aim of the study was to verify the efficacy of CO2-removal technique in reducing Vt and consequently Pplat to obtain a Stress Index value equal to 1.
