- LeonM 7y agoObviously, 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?
- M2Ys4U 7y agoI 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.
- Blakestr 7y agoParamedic 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
- Mountain_Skies 7y agoDoes #1 mean that a person with high blood pressure is more able to survive blood loss than a person with standard blood pressure?
- ldoughty 7y agoNot a medic/doctor, but I would assume higher pressure would result in pushing blood out of your system faster. This probably offsets gains
- agumonkey 7y agoYeah that was my first thought. Doesn't need to be a full replacement, if side effects are minuscule and long term, this would be a superb buffer. Many hospitals are asking for donations. Well now they might ask for subventions :p
- Marsymars 7y agoIf you're bleeding out and compatible blood isn't immediately available, we already have several volume expanders that can be used.
