Based on current reports, it was surprising that the characteristics of many patients with COVID-19 who fulfil the Berlin criteria for acute respiratry distress syndrme (ARDS), are not always like those of patients with typical ARDS and can change over time.While the mechanisms of COVID-19-related respiratory dysfunction in COVID-19 have not yet been fully elucidated. pulmonary microvascular thrombosis is involved is speculated to be involved. Considering that thrombosis is highly related to other inflammatory lung diseases, immunothrombosis, a two-way process that links coagulation and inflammation, seems to be involved in the pathophysiology of COVID-19, including respiratory dysfunction. Thus, the current manuscript will describe the proinflammatory milieu in COVID-19, summarize current evidence of thrombosis in COVID-19, and disscues possible interactions between these two.
