Now intravenous oxygen

Medicine Comments Off

Patients unable to breathe because of acute lung failure or obstructed airway need oxygen to avoid cardiac arrest and brain injury. Boston Children’s Hospital team led by Dr John Kheir, has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood. 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. The report is published in June 27 issue of Science Translational Medicine.
