so how did that transfusion thing work?

given that Miller’s background is as a doctor I assume he did the research or has the first-hand knowledge. So I looked into it:

Direct Transfusion. – The obvious method of performing a direct transfusion is by making an end-to-end anastomosis between an artery of the donor and a vein of the recipient. The most readily accessible artery is the radial at the wrist, and this is indeed almost the only artery that is available. The most accessible vein is the median basilic or the median cephalic at the elbow. The operation of end-to-end anastomosis, using an artery of so small a calibre as the radial artery at the wrist is usually found to be, is one of great technical difficulty ; this effectually prevented transfusion from being used at all frequently. 

Translation: connect the artery to the vein. The vein at the elbow is the easiest, and the artery at the wrist is the easiest but is too thin to be practical. 

Solution—> Here is a diagram of the arm, you can see that both veins and arteries are present at the elbow:

Even though the Brachial artery is hard to find due to it’s location, it’s still possible (and probably the only relatively easy accessed artery that can support this type of transfusion, see quote above). 

From a nursing forum:

Q: What I’ve been having the most trouble with is finding the brachial pulse. If I’m lucky I can find it (it’s usually very faint), but most of the time I can’t feel anything.

A: Follow the bicep down to where it turns into tendon about an inch or so above the crook of your arm, palpate the medial side you may have to kind of push the muscle over to find it.

The things I do for fic research…

If you think fanfictions aren’t thoroughly researched and planned, I must laugh at your face. You should fear fanfiction writers and the fandom at large, they will research everything that could potentially send red flags all over to make the story real. It’s also the reason filmakers, authors, series writing team and those involved in a creative writing process that have a fanbase should always remember not to ridicule fans and their ability to point out your errors. They are the people you don’t want to bullshit, trolling, (I am looking at you BBC), however, is perfectly welcomed.

So much yes. I’ve spent most of this weekend looking up wound repair treatment and recovery times, shoulder dislocations, transfusions, cracked ribs, and motorcycle troubleshooting. A previous miscellaneous weekend was devoted to plants, both looking for something and eventually settling on the acacia and then learning how in the world they might be wasteland planted (to increasing amounts of excitement and omfg). And don’t get me started on wasteland food, lmao.
