Respiratory System Dynamical Mechanical Properties: Modeling in Time and Frequency Domain

Abstract

In order to satisfy the energy requirements of the body, the respiratory system takes up oxygen from the environment and discharges carbon dioxide. The mechanical function of the lungs can be examined by analyzing the lung parameters and its overall function with the aim of recognizing early signs of conditions and tracking disease development. Because of the complexity of the respiratory system, models which mimic the mechanical behaviour of the respiratory system were developed. These models contain parameters which can be assessed and changed to match the behaviour of the model of interest. One of these models is the parallel model which features two mechanically different regions called linear compartments. In this paper, we developed two models representing the parallel bicompartment model, which were made in both the time and frequency domain. After making these models, we were able to obtain plots which show the relationship between pressure, flow and volume represented in time and frequency domain.
