After hemicolectomy to remove a colon carcinoma, a 53 y.o XY is intubated and receives mechanical ventilation with 100% O2. Three days later he has worsening oxygenation and chest xray demonstrates increasing opacification in all lung fields. A transbronchial lung biopsy shows hayline membranes that line distended alveolar ducts and sacs. The fundamental mechanism underlying these morfologic changes is

a) Reduced production of surfactant by alveolar type II cells

b) DIC

c) Aspiration of oropharyngeal content with bacteria

d) Leukocyte-mediated injury to alveolar capillary endothelium

e) Release of fibrogenic cytokine by macrophages
