摘要

利用输入-输出压力-流量关系研究了人体呼吸系统的力学特性。该输入阻抗数据被拟合到系统的集总电类比，然后估计的参数被赋予生理意义。作者提出了一种技术来完善这些参数的解释。他们独立地获得描述大气道的几何信息，并计算其对系统阻抗的贡献。仿真结果表明，该部分作为阻性惯性元件。

Contribution of large airways to respiratory system input impedance

Mechanical properties of the human respiratory system are studied using input-output pressure-flow relationships. This input impedance data is fitted to lumped electrical analogs of the system, and the estimated parameters are then assigned a physiological significance. The authors present a technique to refine the interpretation of these parameters. They independently obtain geometrical information describing the large airways and calculate its contribution to the system impedance. Simulations show that this part acts as a resistive-inertial element.<>
