How is the Murray Lung Injury Score calculated?

Murray score: each of 4 components scored 0 to 4 then averaged. (1) CXR consolidation: 0 (clear) to 4 (all quadrants). (2) Hypoxemia: PaO2/FiO2 >=300=0, 225-299=1, 175-224=2, 100-174=3, =15=4. (4) Compliance: >=80=0, 60-79=1, 40-59=2, 20-39=3, 2.5 = ECMO referral criterion (CESAR trial).

When is ECMO indicated vs conventional ARDS management?

ECMO referral criteria (EOLIA/CESAR): Murray score >3.0 despite optimal ventilation OR pH 6 hours. VV-ECMO (venovenous) for respiratory failure: cannulate femoral vein plus jugular (or bicaval). ECMO specialist center referral mandatory. Prone positioning, high PEEP, and neuromuscular blockade should be exhausted before ECMO consideration.
