London: Scientists claim to have found a new way of injecting oxygen into the blood to keep patients alive even when they can`t breathe during complex operations. The procedure, which works by injecting oxygen molecules enclosed in fatty molecules directly into the bloodstream, could give people an extra 30 minutes of life when they cannot breathe, the researchers said. "This is a short-term oxygen substitute, a way to safely inject oxygen gas to support patients during a critical few minutes," lead researcher John Kheir, of the Boston Children`s Hospital, was quoted as saying by a newspaper. Dr Kheir, who was inspired to begin his landmark research after he experienced a patient`s tragic death, started working on the idea of bypassing the pulmonary system and inserting oxygen directly into the blood.
