PatientEvoPhysio

Free open source Model Library designed to evaluate human physiological evolution in adulthood, childhood, neonatal and fetal life in the face of the occurrence of cardiovascular and respiratory anomalies or different clinical practices (DOI: https://doi.org/10.5281/zenodo.10054996).

Library description

The internal structure of the library is as follows:

As can be seen in the Figure, the library is made up of 8 packages. The content of each package is explained below:

1. Icons: This package contains the icons of all the components that make up the physiological models of the library.
2. Components: This package contains all the components that are used to assemble the different physiological scenarios for evaluating the evolution of patients.
3. Types: Contains particular data types. All of this data is modifications of Modelica's primitive data.
4. Scenarios: They contain multiple models divided into 4 large categories: Adults, children, neonates and fetuses.
5. Connectors: This package contains different connectors that allow interaction between the internal variables of the components.
6. Function: This package contains mathematical functions such as the Hill function, the inverse Hill function, pulmonary or placental respiratory functions that determine changes in time-varying oxygen saturation.
7. Signals: This package contains the components that determine the time-varying behavior of aspects such as the variable elastance of certain vascular components, pulmonary respiration, placental respiration, the foramen ovale, among others.
8. UsersGuide: Contains contact information, acknowledgments of scientific articles related to the development of this library.

Installation

To run this library it is necessary to have the following prerequisites installed:
