More blood loss related questions, quite a few of them, actually.
Let's say that a person has lost 3 units of blood and will die unless they receive a blood transfusion. Having already given the patient intravenous fluids to replace the lost blood volume, about how long would you say the patient has to live without receiving a blood transfusion?
Also, what symptoms would this person go through? Would they be unconscious? Is it correct that they'd have trouble breathing and have low blood pressure? If conscious, would the patient vomit, have headaches, be sleepy, weak?
What if a blood transfusion was possible, but only at a unit at a time, say over a 48 hour period? Would this be enough to save the patient's life?
Okay, I think that's all. If anyone can answer these questions, I'd be so grateful! Thanks.
