[Ultrastructure of the blood-air barrier of dog lungs during the treatment of acute hypoxia using extracorporeal membrane oxygenation].

Electron microscopic studies of lung aerohematic barrier were performed in 10 dogs under condition of severe hypoventilation hypoxia, using membrane oxygenator "Sever-OMR". Acute hypoxia treated with extrapulmonary membrane oxygenation was characterized by less deep and disseminated ultrastructural changes in aerohematic barrier than that treated without membrane oxygenation. The data obtained show positive effect of extracorporeal membrane oxygenation on lung tissues.
