A man-made, pure-white compound called Oxycyte carries oxygen 50 times as effectively as our own blood. Researchers are betting that it’s the best way to treat America’s leading cause of accidental death: traumatic brain injury

THE RED AND THE WHITE
Oxycyte is the newest product in a family of compounds known as artificial blood. The search for a synthetic substitute for human blood began at least as early as the 19th century, when doctors actually tried using milk to replenish blood loss. With the onset of the AIDS crisis in the early 1980s, pharmaceutical companies took on the cause in force, competing to create an artificial substance that could eliminate the problems—including tainted blood and supply shortages—associated with donated blood. The idea was that these substitutes could replace the use of donated blood in transfusions, during surgery, and in patients who had experienced major blood loss through injury.
