Abstract:
A method of determining the well being of a placenta in a pregnant woman having a maternal-placenta-fetal system, the method comprising the steps of:(a) simultaneously monitoring selected maternal and fetal physiological signals; (b) preprocessing said maternal and fetal physiological signals by independently non-linearly or linearly mathematically decomposing said maternal and fetal physiological signals into mathematical constituents thereof and collecting constituents of said mathematical constituents having a highest degree of linearity and/or simplicity; (c) using said constituents having said highest degree of linearity and/or simplicity for identifying a mathematical model describing the maternal-placenta-fetal system, and mathematical parameters describing said model; and (d) determining, according to said mathematical model and said mathematical parameters describing said mathematical model, the well being of the placenta.
