cord-271822-ohkki0ke	Verma, Siddhartha	Visualizing the effectiveness of face masks in obstructing respiratory jets	2020-06-01		.txt	text/plain	3254	187	50	We use qualitative visualizations of emulated coughs and sneezes to examine how materialand design-choices impact the extent to which droplet-laden respiratory jets are blocked. We outline the procedure for setting up simple visualization experiments using easily available materials, which may help healthcare professionals, medical researchers, and manufacturers in assessing the effectiveness of face masks and other personal protective equipment qualitatively. 7 The rationale behind the recommendation for using masks or other face coverings is to reduce the risk of cross-infection via the transmission of respiratory droplets from infected to healthy individuals. 8, 9 The pathogen responsible for COVID-19 is found primarily in respiratory droplets that are expelled by infected individuals during coughing, sneezing, or even talking and breathing. Various studies have investigated the effectiveness of medical-grade face masks and other personal protective equipment (PPE) in reducing the possibility of cross-infection via these droplets.	./cache/cord-271822-ohkki0ke.txt	./txt/cord-271822-ohkki0ke.txt
