The Lung Injury Score can be used to assess the adult patient for the extent of acute pulmonary damage. It can be used both at the onset of a lung disorder and during the course of the illness to monitor changing lung involvement.
Parameters:
(1) chest X-ray evaluated for alveolar consolidation
(2) ratio of the partial pressure of oxygen in arterial blood to the inspiratory fraction of oxygen
(3) PEEP level, if ventilated
(4) respiratory compliance, if known
