Análise de resposta dinâmica do módulo eletro-pneumático da pressão positiva contínua na via aérea modelado por Bond Graph

Continuous Positive Airway Pressure is a ventilation system noninvasive complex currently applied in particular in neonatology. In this context, the parameters must have a controlled setting, since it will have an impact on the survival of premature infants with very low birth weight - which require constant control. The aim of this paper was to propose a mathematical model for the electro-pneumatic module of a Continuous Positive Airway Pressure in newborns system (Neo CPAP) with an interest in quickly check the influence of a particular change parameter on the performance of subsystems. The methodology used to analyze the variables was the mathematical modeling by IDOV technique (validate, identify, design, optimize). This approach leads to an adequate shape for obtaining the physical behavior and characterization of the studied system. The joint system accomplishes results that CPAP function is obtained; research has shown that, by adopting a specific purpose, one can create a better understanding of Assistive Technology and its parameters and how to control it.
