Oxygen Without Donors: The Early Scientific Pursuit of Artificial Blood
Before modern transfusion practices became safe and reliable, doctors often faced heartbreaking limitations . Patients who lost large amounts of blood during surgery, childbirth, or injury had very little chance of survival. Even when physicians attempted transfusions, they frequently encountered complications because they did not yet understand blood types or immune responses. As a result, many early procedures led to severe reactions or death, which made doctors hesitant to rely on transfusions. At the same time, the growing complexity of medicine increased the demand for dependable solutions. Surgeons began performing more advanced procedures, and emergency care became more common. Consequently, the need for a safe, universal blood substitute became more urgent. Scientists began asking a bold question: could they create a substance that mimics the life-sustaining properties of blood without relying on human donors? Breaking Down the Core Function of Blood To answer that question, re...
