Propagation of pneumonia and lung injury. Propagation of pneumonia and lung injury. On day 1, pneumonia originating in the left lower lobe was addressed by intubation, mechanical ventilation, antibiotics, fluid repletion, and routine side-to-side variation of positioning. Despite appropriate treatment, by day 2, the process had become primary (pulmonary) ARDS. By day 7 the original pneumonia site had cleared, whereas the right lung was still involved by the acquired inflammation.
