Copyright HEMO SAPIENS®Hemodynamic Management Modeling ("E") can only be performed while
in the Hemodynamic Management ("G") Page.
Following is an example
of hemodynamic management modeling of a hypertensive patient.
The patient's Hemodynamic
Management Page is displayed below:
(a normodynamic state), while ISI = 1.26 1/sec
(a normoinotropy). As you can see under the heading HEMODYNAMIC MODULATORS, the causes
of this patients hypertension were (a) 25% hyperchronotropy, (b) 51% hypervolemia
and (c) 77% vasoconstriction.
By pressing the "E" key (while in the Hemodynamic Management Page), the panel with analog traces is replaced with the hemodynamic management modeling panel, where the operator can adjust the level of three hemodynamic modulators (volume, inotropy and vasoactivity) and one perfusion blood flow modulator (chronotropy) using the mouse to move the corresponding sliders as to correct the listed deviations in the modulators. The yellow dot represents the original hemodynamic state of the patient, the red dot represents the predicted hemodynamic state after application of therapies correcting the above-listed deviations in hemodynamic modulators. The predicted hemodynamic state is a a vectorial sum of individual therapies:
This modeling example shows the fallacy of current treatment of hemodynamic disorders
by trial-and-error or by a dogmatic application of step therapy or other therapies
designed to treat the cause (i.e., the hypertension) and not striving to identify
the causes and to correct them therapeutically.
A general rule for
selection of dosage of a cardioactive and/or vasoactive drug is:
For displayed
deviations 20-40% use a low dosage of available drug, for deviations 40-60%,
use a medium dosage of available drug, and for deviations >60% use a high
dose of available drug.
