Modeling and Simulation of Physical Parameters of Human Respiratory System

Abstract:

The respiratory system, due to its non-linear behaviour, is of difficult representation through fixed physical components and common control systems. Therefore, mathematical equations, that represents the respiratory cycle; mechanical components, giving dimension and movement to the simulator; and the electronic components, allowing data acquisition and system control are some factors that must be known and synchronized. The presented work describes the implementation of a mathematical model (in MatLab) that reproduces the non-linear behaviour of the respiratory system, allowing the characterization of different pathophysiological situations. In parallel a graphical interface was developed enabling the user track the change in air flow and volume handled during the respiratory cycle and build physiological profiles of different patients.
