| Acute Respiratory Distress Syndrome |
| Lung Injury Score |
| Overview: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 |
| Parameter | Finding |

| alveolar consolidation de 3 quadrant |
3 |
|
| alveolar consolidation de 4 quadrant |
