Method and apparatus for inspiration have continuous determination of the intratidal dynamic respiratory mechanics by means of multiple regression analysis by means of sliding

摘要

The invention relates to a method for quasi-continuously determining the intratidal dynamic respiratory mechanics by means of the parameters basic dynamic pressure p0, flow resistance r, the volume extensibility c, the inertial parameter i as well as the actually prevailing pressure in the alveoli p_alv.For this purpose, a sliding analysis window is displaced via the data set, so that by means of multiple regression analysis, as it were, the determination is made possible with any desired resolution.In this way, it is possible, independently of the ventilating the determination of the courses of these intratidalen breath of mechanical parameters be carried out quasi-continuously, respiratory measurement data from a in its circumference freely selectable sliding "window area" are determined such that it by means of a section of the volume axis or the pressure axis or the flow axis are defined and that these data associated with the window area for the "local " calculation of p0, r, c, i and / or p_alv be used for this purpose, which linear or non-linear function courses for the relevant parameters are determined, so that by means of the displacement (sliding) of the window along the respective axis a quasi-continuous course of the parameters of the respiratory mechanics results.Furthermore, from the quasikontinuielichen parameter values continuous (continuous) are determined approximations of mathematical functions.
