Modeling obstetric cardiovascular physiology on a full-scale patient simulator

Area of Science:

• Cardiovascular Physiology
• Computational Modeling
• Medical Simulation

Background:

• Existing cardiovascular models lack patient-specific hemodynamic simulation capabilities.
• Physiological alterations in specific patient populations are not fully characterized in existing literature.

Purpose of the Study:

• To adapt an existing cardiovascular model for simulating hemodynamics in a specific patient population.
• To identify critical physiological parameters essential for accurate patient-specific cardiovascular modeling.

Main Methods:

• Iterative testing and comparison of simulated vital signs with target values.
• Literature review to identify and define undefined physiological parameters.
• Adaptation of an existing computational cardiovascular model.

Main Results:

• Identified critical cardiovascular model parameters not fully defined in current literature.
• Demonstrated the necessity of iterative refinement and empirical adjustments for less-described physiologies.
• Provided a list of parameters for future patient-specific modeling efforts.

Conclusions:

• The first attempt at adapting a cardiovascular model for patient-specific hemodynamics revealed significant gaps in parameter definition.
• Future modeling requires iterative refinement, empirical data, and identification of novel parameters.
• Extending this approach to other systems, like the respiratory system, will necessitate similar methodological processes.
