Unfortunately Guinness doesn’t carry oxygen around you body.

Or are you suggesting an anaesthetic?
 
Sweetheart stout would be better than Guiness, though other traditional low alcohol milk stouts would do. Traditionally given to those such as the elderly, those recuperating from surgery, nursing mothers, etc.,

The low alcohol in sweetheart stout at 2% is the same level as that small beer that was the drinking water of the past. It doesn't need much alcohol to sterilise liquid enough to kill most buggits and diseases.
I think most milk stouts now though are somewhere just above 4%....not imperial stout about 9% like guiness.

Honestly, getting enough liquid into the body, and stopping it running out, and the body will boost the blood itself.
Traumatic injury aside, and just how traumatic are we talking about ?

Cyclingrelf went through a plate glass door years ago, and she lost a lot of blood....and some of it was arterial.
We might ask Susanah to join the conversation ? Professionally she's a pharmacist so might have cogent input.

This is interesting!

One issue might be that I wouldn’t give permission as doner or as recipient.

If you have the facility to type my blood then you will probably have facility to do the job conventionally.

In a hospital it is always done using a blood bag even when the interval is a few minutes and less than 2 meters.

(Gravity alone works with a blood bag but there are pressure cylinders where a lot of blood is needed in an artery as for a burst aorta. )

If you can find the identical twin that I didn’t know I’d got them maybe - just maybe.

Thats a very self-self-self perspective

Maybe you wouldn't get offered of a top up in the first place.
Have you considered that.
 
This is the general loss vs effect guidance :)

Blood LossPercentage of Total Blood VolumeEffects
0.25 L (250 mL)~5%No significant effect in a healthy person.
0.5 L (500 mL)~10%Possible mild dizziness, slight weakness. Often tolerated well.
1.0 L (1000 mL)~20%Noticeable weakness, fast heart rate (tachycardia), possible mild shock.
1.5 L (1500 mL)~30%Confusion, low blood pressure, rapid pulse, cold and clammy skin. Moderate to severe shock.
2.0 L (2000 mL)~40%Severe shock, fainting, extreme weakness, very low blood pressure, risk of organ failure.
>2.5 L (2500 mL)~50%Life-threatening, unconsciousness, likely death without immediate treatment.


And for comparison

The average adult has about 4.5 to 5.5 liters of blood in their body, which is about 7% of their body weight

Oh come on!

I was a blood donor until my donation ceased to be acceptable.

We’re talking about a totally hypothetical field operation where no one has enough information and the skills are untested today.

In hospital, even when the donor is present in a bed right next to the recipient, the blood still goes into a bag with a drip control on it. ( I have experience of this as one of my children had a very specific blood type.)

I'm joking Pattree!!
 
Funnily enough I've been clearing out old first aid stuff today....came across an Israeli pressure bandage....long timed out, but still sealed, sterile, etc., and since there's nothing to go off, most unlikely to be spoiled.
What on earth I'm going to do with such a thing these days though.....
 
I think the more important concern here is what TeeDee has planned. If anyone had an invite to dinner recently I suggest you wear kevlar sleeves!

For my sins I was rewatching TWD , Season 2 Episode 1 where Carl ( " Carrralllllllll!!! " ) gets shot and Officer Grimes gets used as a blood bag whilst his son recuperates.

It also isn’t a simple as just blood typing. There are a whole host of antibodies to be considered aswell, that can cause severe reactions etc. think of a transfusion as a ‘liquid organ donation’. Clotting also needs to be taken into account.

It has been done many times in the past, but not anymore recently than before ww1 I don’t think.

Donor Arterial/recipient venous anastomosis would work pump wise, and it has been done that way before.

Not recommended by the NHS though!

Is it as simple as the donor heart IS the pump ? That is the positive head of pressure?
If the donor is type O Rh negative then I imagine you don't need to know the receiver's blood type.

If you have a flexible tube attached to a cannula in both donor and receiver, you might be able to pinch the tube and run your fingers towards the receiver; a kind of makeshift peristaltic pump.

Blood donation centres generally take 500ml from a donor, I think. When I was a donor, I think I used to go twice a year.

Thank you - yes as a make shift pump a bit of manual pressure may well work - I guess in those type of scenarios one isn't going to worry too much about certain 'best practices' - its either try or die.
 
Blood type and Rhesus is not the only factor as MrEd said. There a whole lot more blood types than commonly known about. Some can cause serious issues.

If you have the kit to go arm to arm then you are likely to have the kit to go arm to bag then bag to arm. A safer and more controlled method.

One final point, movies are not real and in those that have done this IRL it would not have been done at all. It is makebelieve and I am sure people can make that determination but I still thought it worth bringing up.
 
I can recognise the OP conjecture. It’s a reasonable question. On the other hand the objections being raised are totally valid.

The problem lies with the context and boundaries to the OP. They require considerable specialist resources and knowledge in a field setting and that just isn’t going to happen. Hepatitis and blood solidification are as much part of the context as the “absolutely no option but to do it” scenario and must be included in that option assessment.

Regardless of how it might be conjectured to be done, the very narrow conditions set in the OP aren’t going to happen.

I suppose that my answer to the op is that:
You are very unlikely to be able to do it.
You shouldn’t do it.
and
I’d put the odds of survival a very long way beyond surviving the need for CPR. You could very possibly be the cause of death.
