Based on haemoglobin extracted from expired blood stocks, however seems promising.
If pre-oxygenated it would certainly save lives, like a super transfusion without the volume and consequent blood pressure increase.
(IIRC blood isn't delivered oxygenated)
It would also work even with minimal/non existent pulse in conjunction with ECMO, as it delivers oxygen to ischaemic cells first.
Discuss.
