A team led by researchers at Boston Children’s Hospital has designed tiny, gas-filled microparticles that can be injected directly into the bloodstream to quickly oxygenate the blood. Even if you can’t/aren’t breathing. And it can keep people alive for 15 to 30 minutes. The particles are pockets of oxygen in a layer of lipids, specifically fats. This is then suspended in liquid, which can be injected into the blood steam. The oxygen then “squeeze[s] through capillaries,” according to Dr. John Kheir of Boston Children’s Hospital. This invention, it will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.
