Levitt et al reported an early acute lung injury (EALI) score for predicting acute lung injury prior to respiratory failure. The authors are from Stanford University and University of California San Francisco.
Patient selection: acute care setting
Parameters:
(1) oxygen requirement in liters per minute
(2) respiratory rate in breaths per minute
(3) baseline immunosuppression

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 4
• A score >=2 had a sensitivity of 89% and specificity of 75% for progression to acute lung injury.
