Researchers at the Indian Institute of Technology in Madras (IITM) found that holding your breath may increase the risk of infection with corona, according to the researchers, the process of transferring virus-laden droplets to the deep lung increases with the decrease in the frequency of breathing.
The research team measured the frequency of breathing in the laboratory and found that low breathing frequency increases the survival time of the virus, and increases the chances of sedimentation, and thus infection with the Corona virus.
The research was led by Professor Mahesh Panchaganula, Department of Applied Mechanics at IIT Madras, and the results of this study have been published in the famous international journal Fluid Physics.
He said that the Corona virus has opened a gap in our understanding of deep systemic pulmonary diseases, our study reveals the mystery behind how particles are transported and deposited in the depths of the lung. Aerosols deep into the lung, demonstrating the need for such research.
According to TimesNowNews, the team worked to gain a deeper understanding of how to determine the flow rate of virus-laden droplets to deposition the virus in the lungs. In their research, the team reported that holding your breath and a decrease in the respiratory rate can increase the chances of the virus depositing in the lungs.
The study was conducted to pave the way for developing better treatments and drugs for respiratory infections, and the group's previous work also highlighted the great variation in aerosol absorption from one individual to another, indicating why some people are more susceptible to developing airborne diseases than others.
Airborne infections such as the Coronavirus are highly spread through sneezing and coughing, as many small droplets are released immediately.
The IIT Madras research team mimicked the dynamics of droplets in the lung by studying the movement of droplets in small capillaries whose diameter was similar to those of tracheids. They took water mixed with fluorescent particles and produced an aerosol from this liquid using a nebulizer. This fluorescent aerosol was used to track the movement and deposition of particles in Capillaries.
The researchers studied the motion of fluorescent aerosol particles in capillaries with sizes from 0.3 to 2 mm covering the range of bronchial diameters, and found that the deposition is inversely proportional to the ratio of capillary dimensions, indicating that droplets are likely to precipitate in long bronchioles.
In the future, the team intends to continue this work to understand how droplets carrying the Coronavirus travel to the lungs because the process by which the virus moves from the nasal cavity to the deep lung is still unknown, and understanding the physics of this phenomenon may be critical in mitigating the progression of the disease.
