[Estimation of visco-elastic parameters of the bronchial system based on measurements obtained by dynamic...

Visco-elastic parameters of the bronchi system are represented by the viscous modulus and the recoil static pressure. In several generations, values of the cross-sectional area of the bronchi are defined at various moments by the results obtained with dynamical tracheo-bronchography. By means of these measures and the use of a model describing the air flow in elastic bronchi, a calculation procedure of the visco-elastic parameters has been established.
