Obviously, any blood is better then no blood. But will you survive that long on artificial blood if it doesn't contain all the right properties for your body?

I would have thought that getting blood into trauma patients in the field would be the main application for this?

Once back in a hospital setting they could switch to using real blood.

Paramedic here - two main areas of concern regarding blood in the prehospital/emergency setting -

1 - Volume - You need enough fluid in a closed system to maintain pressure to push that fluid.

2. Oxygen carrying capacity - Oxygen binds with red blood cells which then deliver it to every cell in your body.

Right now the prehospital setting can more or less manage #1, we have been for a century with Normal Saline.

There is some stuff circulating (pun intended) regarding fluids that can transport oxygen but it will be years before we can use it

Does #1 mean that a person with high blood pressure is more able to survive blood loss than a person with standard blood pressure?

Not a medic/doctor, but I would assume higher pressure would result in pushing blood out of your system faster. This probably offsets gains
