RESUMO

A Darcian mathematical model for heat and mass transfer through lung tissues under high-frequency ventilation has been studied. High-frequency ventilation is an effective treatment that helps premature infants and patients with severe respiratory distress. A lung-ventilator system under high frequency is described by Navier-Stokes and viscoelastic tissue deformation equations, while the transient convection-diffusion through this system is based on bioheat transfer and concentration equations. The mathematical functions distributions are discussed and shown graphically for different values of biomechanical properties of the lung such as the Young's modulus for the solid E and permeability K.
