A. Hematoxylin and Eosin-stained sections staining from representative regions of the lung parenchyma of post-mortem lung tissue of 8 non-COVID-19 ARDS (patient numbers 10–15, 17,18) and 3 non-COVID-19 non-ARDS (patient numbers 9,16,19) patients. Scale bar is 3 mm. B H and E staining at higher magnification: Diffuse alveolar damage, microthrombi and edema were observed. Arrows show proteinaceous exudate in the airspaces. Scale bar is 200 microns. C Vascular structures in lungs from non-COVID-19 sources. Arrows show thrombi in vessels. About 40% of the fields from non-COVID ARDS showed thrombi. Very few microthrombi were observed in non-COVID non-ARDS lungs. Scale bar is 100 microns
