Abstract(in Japanese) (See Japanese page)
Abstract(in English) A theoretical approach was challenged to analyze the temporal changes in airway pressure and flow when the impedances among the airway tracts are different. Each compartment was comprised of time invariant elastic and resistive components. The Euler-Lagrange differential equations for both sides of respiratory tract were solved numerically. Increases in elasticity of airway tract and resistance to flow in one side of airway tract resulted in considerable increases in airway pressure and airway flow. The increases of the weighting coefficients for minimization of rate of change in air flow rates caused monotonous increase in airway pressure and inverted pattern of airway flow.
