[Peculiarity modification mechanical property of a pulmonary tissue in the period of physiological pregnancy].
In the period of pregnancy are reduced elastic of property of a pulmonary tissue. More than in 2 times is enlarged an extensibility, as at the expense of participation of the surface active agents, and some factors of parenchyma. The conditions for augmentation of the size of alveolus's, delay in them of air and infringement of a bodily machinery of respiration are framed. Obviously, as a result of rising a hydrophilic nature the effective viscosity plasticity of system of a pulmonary tissue is reduced, that causes infringement of alveolar ventilation (close-effect) and hypercarbondioxide in respiratory ways. The combined influence of the factors of pregnancy at some women promotes formation dynamic hyperinflation mild, development of respiratory failure and hypoxia to complications on the part of a fetus.
