Modeling of breathing, precipitation of medical drugs in aerosol form, and curing of Coronavirus infection by using a thermal helium-oxygen mixture

Abstract

The study is aimed at calculating the air flow and modeling precipitation of droplets of medical drugs in human lungs. The problem is solved by using a previously designed three-dimensional model of the human bronchial tree. The gas flow in lungs and precipitation of aerosols are computed by the method of stage-by-stage calculation of the flow in the bronchial tree, which allows the air flow and precipitation of aerosol droplets to be traced over all bronchial branches up to alveoli. Human breathing is simulated by an example of COVID-19 curing with the use of a thermal helium-oxygen mixture. It is shown that breathing of the thermal helium-oxygen mixture requires less effort from the patient than breathing of air. Equalization of the temperature of the heated inhaled gas with the human body temperature is shown to occur in the upper branches of the bronchi. © 2021 Author(s).
