Discussed in APL Bioengineering, researchers created a high-fidelity respiratory simulator that accurately represents the interplay between the abdomen, diaphragm, lungs and pleural space, the fluid-filled membrane surrounding the thorax and lungs. The model, using swine lungs, soft robotic materials and artificial muscles, allows precise tuning of pressure in each part of the system, so specific disease conditions can be tested. It also proved extremely useful for testing ventilator-only respiration by removing the elastomeric diaphragm.Read more
One of the many questions researchers have about the COVID-19 virus is how long it remains alive after someone infected coughs or sneezes. In Physics of Fluids, researchers examine the drying time of respiratory droplets from COVID-19-infected subjects on various surfaces in six cities around the world. Using a model well established in the field of interface science, the drying time calculations showed ambient temperature, type of surface and relative humidity play critical roles.Read more
While both sexes have the capacity for phenomenal athletic achievements, women on average must work harder to breathe during strenuous exercise compared to men, according to new research.Read more
A team of engineers and physicians at the University of California San Diego is working to turn emergency hand-held ventilators into devices that can work autonomously for long periods of time, without human input.
Findings from CT scans provide new insight that could lead to quicker diagnosisRead more
In one urban ED that sees approximately 12,000 pediatric patients a year, a team of emergency medicine physicians devised a model that would optimize resources, reduce length of stay dramatically, and increase patient satisfaction.Read more
