MAP20071020428Podgórski, AlbertAn Improved mathematical model of hydrodynamical self-cleansing of pulmonary alveoli / Albert Podgórski and Leon GradonSumario: The present paper postulates a hydrodynamical mechanism of pulmonary alveoli cleansing and explain the role of the lung surfactant system in the phenomenon. Then a new, significantly refined mathematical model of the dynamics of the layer lining alveoli is derived and tested numerically in order to check theorically whether the mechanism postulated can explain the phenomenon observed and to establish the influence of various physicochemical and physiological parameters on the rate of alveolar cleansingEn: The Annals of occupational hygiene. - Oxford [etc.]. - nº 4, August 1993 ; p. 347-3651.
