Currently, the window for resuscitating a person in cardiac arrest is very short. On the order of just a few minutes before ischemia, i.e. the cessation of blood circulation depriving an organ of a vital supply of oxygen to the point of causing necrosis. When this phenomenon hits the brain, it can create potential irreversible damage.
But science is moving forward: at Sun-Yat-sen University, in southeastern China, researchers have managed to resuscitate, for three hours depending on the case, the brains of several pigs almost sixty minutes after the stopping blood circulation. Scientists have notably discovered the major role of the liver in resuscitation and preservation of the brain from lesions in pigs. A major medical discovery which could, in the future, help to better treat cardiac arrest in humans, which affects 50,000 people in France each year, with a survival rate of 5%.
