Ice slurry technology can save heart attack victims, surgery patients

"When treating cardiac arrest victims, doctors can't call a time-out. Without the ability to obtain fresh oxygen from blood pumped through the body, brain cells start to die in just minutes. Within 10 to 20 minutes after the heart stops beating, the clock has run out. Even if doctors can get the heart ticking again, the brain has died. Recently, however, researchers have begun to develop a new technique that can reduce the brain and other organs' demand for oxygen, giving doctors precious extra time to diagnose and treat critical patients in emergencies while also protecting the heart, brain, kidneys and spinal cord in planned surgeries" - Argonne National Laboratory
