It was discovered that the deposition is inversely proportional to the facet ratio of capillaries which means that droplets are more likely to deposit in longer bronchioles.
So, the transportation of the virus-laden droplets deep into the lungs will increase with a decreased respiration frequency. This is as a result of low respiration will increase the time of residence of the virus, subsequently growing the possibilities of the an infection.
The research was led by Professor Mahesh Panchagnula Department of Applied Mechanics, IIT Madras and his two different students.
According to Panchagnula, “Our lungs have a branched structure, it has bronchioles that are dichotomously branched. This means each bronchiole branches into two and these go on for 23 generations. The deeper generations, 17 to 23, is where the aerosols meet the blood.”
The findings of this research had been printed within the worldwide journal ‘Physics of Fluids’.
“Covid-19 has opened a gap in our understanding of deep pulmonological systemic diseases. Our study unravels the mystery behind how particles are transported and deposited in the deep lung. The study demonstrates the physical process by which aerosol particles are transported into the deep generations of the lung,” stated Panchagnula, whereas elaborating on the necessity for such analysis.
