圧力差評価等に用いられる関連パラメータ差の測定および監視方法
Document Type and Number:
Japanese Patent JP4827283
Kind Code:
B2
Abstract:
Means and methods for using calculated correction quantities to modify measured parametric values to arrive at a closer approximation of an actual parametric differential. The correction quantities used herein are obtained by preliminarily subjecting the system parametric transducers to various pre-selected parametric values and recording the corresponding measured values for each transducer in a data table for later use as or in correction quantities. A first use of such correction quantities is to interpolate relative to the closest data table values to the operationally measured parametric value and use the resulting interpolated value as the corrected parametric value. This interpolation is preferably performed for each of two parametric transducers, one for each of two associated subject substances. The resulting corrected parametric values are then subtracted to obtain the approximated parametric difference. A beneficial use is in determining pressure differences between associate fluids separated by a semi-permeable membrane, a value called the trans-membrane pressure or TMP.
