A team led by researchers at Boston Children's Hospital has designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body. The invention will allow medical teams to keep patients alive and well for 15 to 30 minutes. It's one of the best medical breakthroughs in recent years that could save millions of lives every year.
The microparticles consist of a single layer of lipids (fatty molecules) that surround a tiny pocket of oxygen gas, and are delivered in a liquid solution. According to John Kheir from Boston Children's Hospital, an infusion of these microparticles into animals with low blood oxygen levels restored blood oxygen saturation to near-normal levels, within seconds.
