Researchers from Case Western Reserve School of Medicine in Cleveland, Ohio made a prototype of an artificial lung which reaches gas exchange efficiencies almost equal to the genuine organ. The small device does not need extra oxygen, it works with normal air. Joe Potkay, a research assistant professor in electrical engineering and computer science published the technique this week in the journal Lab on a Chip.
The scientists developed this prototype while keeping track of the natural design of our lungs. It is made of breathable silicone rubber acting as blood vessels that get as small as one-fourth of the width of a human hair. Because it works on the same scale as normal lung tissue, the team was able to shrink the distances for gas diffusion compared to current techniques. Tests using pig blood show oxygen exchange efficiency is three to five times better.
One of the big advantages of this system is that Read more »
