  1. The positive extravascular lung water (EVLW) test is defined as EVLW/ABW of greater than 10 mL/kg, EVLW/PBW of greater than 10 mL/kg, and EVLW/PBV of greater than 1.5. ABW, actual body weight; ALI, acute lung injury; ARDS, acute respiratory distress syndrome; CI, confidence interval; LHR, likelihood ratio; PBV, pulmonary blood volume; PBW, predicted body weight; sLI, severe lung injury.
