So a potassium drip and plenty of Guinness should see you right?
Unfortunately Guinness doesn’t carry oxygen around you body.
Or are you suggesting an anaesthetic?
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.
This is the general loss vs effect guidance
Blood Loss Percentage of Total Blood Volume Effects
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.
Oh come on!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.
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 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!
If the donor is type O Rh negative then I imagine you don't need to know the receiver's blood type.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.
