The artificial blood is created by extracting hemoglobin — a protein containing iron that facilitates the transportation of oxygen in red blood cells — from expired donor blood. It is then encased in a protective shell to create stable, virus-free artificial red blood cells. As these artificial cells have no blood type, there is no need for compatibility testing. The synthetic blood can reportedly be stored for up to two years at room temperature and five years under refrigeration.
This is fuckin huge if it turns out to be a winner. I mean, almost on the level of the discovery of penicillin big. I did 15 years in EMS, and the single biggest problem in Trauma care is the lack of blood substitutes. Once those blood cells leave the body, that’s it, they’re gone, and either you’ve got replacement blood or you don’t. Artificial blood has been one of the holy grail pursuits of medicine for decades, and we’ve had many, many dead ends with it. Hopefully they’ve cracked it.
