Alpo Posted February 18, 2019 Share Posted February 18, 2019 When you're doing a direct transfusion, how do they know when to stop? If I'm giving blood, they stick a needle in me attached to a hose, and put the other end of the hose in a measuring cup. When the level gets to a pint, or a quart, or a half gallon - however much they want - they stop. But if, for example, they got Hardpan laying on the table - bled white - so they hook me up to give him a refill, how do they know when he's full? They just let me drain until I turn ghost pale?

Imis Twohofon,SASS # 46646 Posted February 18, 2019 Share Posted February 18, 2019 They have a instrument which clamps the tongue, like a caliper, and as it records the lessening thickness it messages the nanobots running the pumphouse (microscopic)to cut back on flow. When complete you are given an injection of nitroglycerin through the needle which starts a controlled series of miniature explosions within the blood stream expanding your blood volume back to it's original volume. Late cutoff can result in extreme amounts of flatulence. Imis (todays science wizard) Link to comment Share on other sites More sharing options...
Father Kit Cool Gun Garth Posted February 18, 2019 Share Posted February 18, 2019 All I can add is that it does require that the person performing said transfusion has the right instruments. Link to comment Share on other sites More sharing options...

Smoken D Posted February 18, 2019 Share Posted February 18, 2019 Generally till when you pass out. That lets them know that's enough. Sometimes they have you squeeze a ball and if you are more valuable than the patient you squeeze the ball 90 times and that is enough. If the patient is more valuable till your eyes bulge out and turn white. That means you are finally out of blood. Link to comment Share on other sites More sharing options...
Ramblin Gambler Posted February 18, 2019 Share Posted February 18, 2019 They check the dipstick they installed in you before the transfusion began. Link to comment Share on other sites More sharing options...

J-BAR #18287 Posted February 18, 2019 Share Posted February 18, 2019 Additional Info: Patients can survive massive blood loss if their blood pressure stays in normal range. That is why EMTs start a saline IV drip rather than attempting transfusions in the field --- keep the blood pressure up by maintaining total circulatory volume. Humans can survive up to about 90 % loss of their red blood cells if the blood pressure is maintained. They won't be feeling good, they will be gasping for each breath, but they will be alive.
