Low breathing frequency would increase the risk of COVID infection- IITM research study
Posted on: 12/Jan/2021 9:25:56 AM
in a study that was published in the International Journal Physics of Fluid, some researchers belonging to IIT-Madras have mentioned that holding breath might increase the risk of getting Covid-19 infection.
It is worth mentioning that the IITM researchers have modelled breathing frequency in the lab to know about how the rate of flow of droplet with virus determines its deposition in the lungs. The study has revealed that the low breathing frequency increases the time of residence of the virus and thereby would increase the chances of deposition and rate of infection. It has been found out that a person susceptibility to Covid-19 infection has been related to the multi scale lung structure.
Professor Panchagnula , department of Applied Mechanics, IITM, spoke about how Covid-19 infection has opened up a gap in our understanding of deep pulmonological systemic diseases.
He explained about the research study that demonstrates the physical process by which aerosol particles get transported into deep portions of the lungs. For developing better drugs and therapies for the respiratory infections, the study was conducted. The research study also had other scholars like Mr. Arnab Kumar Malik and Soumalya Mukherjee.
Droplet dynamics in lungs imitated:
It must be taken into account that airborne infections such as Covid-19 spread through coughing and sneezing due to instant release of tiny droplets. In the lab, small capillaries of the same diameter as similar to that of bronchioles were used to study the droplet movement. By this, the research tem imitated droplet dynamics in the lung.
It was brought to light by the professor that the research team took water mixed with fluorescent particles and then generated aerosols from this liquid by using a nebuliser. Information collected is that these fluorescent aerosols were used to track the movement and deposition of particles in the capillaries.
