The impact of the hypoxia-VEGF-vascular permeability on COVID-19-infected patients

Article, Perspective / By

Leaking plasma from blood vessels triggered by COVID-19 infection plays a crucial role in causing pulmonary atelectasis (lung collapse), which fills up the lung air sacs with liquid and the lung becomes deflated. If sufficiently large areas of the lung tissue become deflated by this problem, the lung tissue can no longer take enough air …
