Lower tidal volumes for ARDS: 6ml/kg + Pplat < 30 vs 12ml/kg + Pplat < 50cmH2O

Clinical Question

In patients with Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS), does ventilation with lower tidal volumes compared with traditional higher tidal volumes reduce death or ventilator-free days?

Critical Appraisal

Key findings

Low Vt > dec mortality, increased vent free days

Critique

High volumes in control group.
