Computational study of the vibrating disturbances to the lung function

TL;DR

This paper models how vibrating disturbances, such as noise, affect lung function by simulating air flow in the trachea-bronchial tree using a nonlinear one-dimensional model.

Contribution

It introduces a nonlinear one-dimensional model to study the impact of vibrations on lung air flow, aiding understanding of physiological effects and protective strategies.

Findings

Vibrations can disrupt lung airflow dynamics.

The model predicts physiological responses to acoustic impacts.

Potential for developing protective measures against noise-induced disturbances.

Abstract

Frequently during its lifetime a human organism is subjected to the acoustical and similar to them vibrating impacts. Under the certain conditions such influence may cause physiological changes in the organs functioning. Thus the study of the oscillatory mechanical impacts to the organism is very important task of the numerical physiology. It allows to investigate the endurance limits of the organism and to develop protective measures in order to extend them. The noise nuisances affects to the most parts of the organism disrupting their functions. The vibrating disturbances caused to the lung function as one of the most sensitive to the acoustical impacts is considered in this work. The model proposed to describe the air motion in trachea-bronchial tree is based on the one dimensional no-linear theory including mass and momentum conservation for the air flow in flexible tubes.
