Answers: No, blood doesn't last forever!! Blood cell have a typical natural life span of approximately 120 days. The reason a creature always have blood cells is because of the BONE MARROW.
So unless here is some process going on that is chewing up the recently transfused blood cells or in that is active bleeding, transfused blood cell will last for a while. They may not later the 120 days but they will be around for a good time.
It last as long as the patient's own blood would last--i.e., pretty much forever, assuming good robustness, no bleeding issues, etc.
Usually transfusion is needed because the recipient isn't glowing and/or is bleeding or has bled. Some of the trial donated blood may be damaged by disease or lost through bleeding, same as his own blood be.
