[Functional and morphological characteristics of lung contusion]. / Funktsional'no-morfologicheskie osobennosti ushibov legkogo.

Interrelated disturbances of functions of the external ventilation, cardiac activity and hemodynamics in contusion of the lung in experiment are always of a phasic character and are distinctly dependent on the volume of the respiratory parenchyma injury. The most pronounced disturbances of respiration and cardiac activity are observed by the end of the first day and the beginning of the second day after trauma. The decreased activity of the pulmonary surfactant and alteration of permeability of the aerohematic barrier play a substantial part.
