is dead space a type of anatomic shunt in the lung

With normal lung compliance and many of them not in respiratory distress, hypoxemia does not correlate with their clinical condition.

1,2 The disease process is been treated as acute respiratory distress syndrome (ARDS) but it is not typical ARDS. COVID-19 made us to think about this forgotten approach.ĬOVID-19 lung injury includes viral medial inflammation, alveolar epithelial dysfunction, impaired surfactant, alveolar collapse, and increased pulmonary artery pressure patients. Silent hypoxemia can last forever but individuals could present to a healthcare facility with this condition occasionally. 1 It applies to any lung pathology which causes a reserved amount of shunt while saving the rest of the lung such as lobar pneumonia or atelectasis. 45: 227–243.With Coronavirus disease of 2019 (COVID-19) pandemic, silent hypoxemia (significant hypoxemia without dyspnea) is a phenomenon to understand with associated shunt physiology, preserved lung compliance, and lack of dead space.
