Injectable Oxygen

by Christopher Paul on July 23, 2012

The Atlantic highlights how injectable oxygen may, one day, help saves lives:

”Researchers led by Harvard Medical School’s John N. Kheir engineered tiny, gas-filled microparticles, which were about three micrometers in size and invisible to the naked eye. They used a device called a sonicator, which uses high-intensity sound waves, to produce a foamy liquid solution with microparticles that consist of a single layer of lipids that trap a tiny pocket of oxygen gas. They then injected the resulting mixture directly into the bloodstream of rabbits that were severely oxygen-deprived.

Within seconds, infusions of the microparticles restored the blood oxygen saturation of these mammals to near-normal levels. When the rabbits’ windpipes were completely blocked, the solution kept them alive for 15 minutes without a single breath and reduced the likelihood of cardiac arrest and organ injury.”
