How long until we don't need lungs/heart/digestion/etc. any more? With artificial blood it becomes much easier. I think we'll see the 'brain in a vat' in 20 years. This is a huge step towards immortality.
In the Year 2525.

A doctor in charge of a blood extraction campaign explained to me that this is exactly the reason why there is a constant high demand of blood donors. Between hospitals there are exchanges daily of blood (you might have a certain blood type that another hospital needs right now), but a lot of blood does get wasted, because of the short times it has. They also separate blood in different kinds (platelets I think it wa…
Do you know if there is any kind of inventory management system that helps blood banks balance their supplies?
I don't know the answer to this, but if they do, they should share this information with the public so the public can be aware and more readily volunteer when needed.

#73On page#2 under "Preparation of HbVs and H12-(ADP)-liposomes" am I reading it correctly that this "artificial" blood is still derived from blood?
Yeah, it sounds to me like it's 'artificial' in the same way that orange juice made from concentrate is artificial.
There is a substantial benefit though:
The artificial blood can be stored at normal temperatures for more than a year.

They compared plasma without platelets (PPP, platelet poor plasma) combined with their crafted liposomes to platelet rich plasma (PRP). Therefore some donored plasma was needed, to have only a difference in the platelet concentraton. Their artificialy synthesized liposomes could then replace the platelets in the study.

#75From what I understand (also heard about this in a podcast recently), they take existing blood of any type and are able to modify the RH and type. So blood still needs to be donated but it can be any Typs and RH as that is what can be modified to any type and RH now.
The donored blood was only needed for the plasma base in their trial.

Its not really about artificial blood but some platelet replacement based on liposomes. Take a look at the full paper.

I had experience with one such group (Jehovah's Witnesses), so I can speak only about them, but yes, I believe they would happily accept artificial blood. The transfusion ban for JWs is related to their interpretation of Bible's verses about blood as a symbol, and verses banning consumption of blood. They already accept some blood-derived medication; generally, the smaller subcomponent of blood something is, the more…
I understand this is a personal matter but I will not accept anything that I know of having been derived from blood.
I'm curious about the range of derivation from blood. For example, if I took a sample of your blood and made a product that was essentially cloning your blood, would that be the same?
Some people's spiritual rejections lie more in the "we're playing God we shouldn't do x" whereas what you are describing is something in regard to the sanctity of the blood.
Actually to further my understand, would you be permitted to receive blood that you yourself had donated and had been stored for your personal use in the advent of a medical emergency? Again, I'm not trying to pry or question the validity of your beliefs, just seeking to understand.

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

Right. Didn't want to go into too much details here. From what I remember from a decade ago, the "full" blood and the four main fractions were strictly forbidden, and everything further down was left as a matter of individual's conscience.
