Hemoglobin Based Oxygen Carriers

Hemopure is a polymerized hemoglobin that's been around now for i guess two decades and is largely the same product to the best of my knowledge. The state at half life is about 19 hours so typically it's something that is a bridge tool that only lasts sort of a day at a time for infusion then there's a another company called sanguine that in addition to polymerizing it added something on it that makes it stay in the circulation longer but they're not currently available even under emergency IND though i could be simply unaware if it's it's been made available again.
