An artificial lung is a prosthetic device that is implanted into the body to replace biological lungs. It is different from a heart-lung machine in that it is internal and designed to take over the functions of the lungs for long periods of time rather than on a temporary basis. Recent developments include a device that uses small hollow fibers and the heart's own pumping power to oxygenate blood. It may be necessary for a person to receive artificial lungs if theirs become diseased or damaged beyond repair.
Researchers from Cleveland have managed to create an artificial lung that reaches an efficiency comparable to that of the real organ, by using air, instead of pure oxygen, as an essential element. There is still a long way to go, and human transplant is years away, but the results so far are extremely encouraging, and [...]
