Mathematical Simulation of the Cardiopulmonary System

Abstract

Multi-chamber mathematical simulators of the circulatory and pulmonary systems have been developed. These are capable of examining the effects of whole-body acceleration (WBA) for any body position and a variety of breathing maneuvers. The circulatory model has been used to examine the effects of oscillatory WBA with good correspondence between simulator results and available experimental data. The pulmonary model has been used in an extensive study of effects of sustained WBA on pulmonary mechanics and ventilation and the effectiveness of altering the seat back angle in improving WBA tolerance. It was found that WBA effects on pulmonary function are markedly affected by body angle and the optimal angle is between 60 and 75 to the effective G axis. The pulmonary and circulatory models are currently being merged to produce a model of the complete circulatory-respiratory system. A bio-feedback model for each system will be incorporated to complete the simulator. Keywords: Anatomical models, Mathematical models. (kt)
