In brief: Depends on patient

A unit of blood can be infused in about 2 minutes for severe trauma, or over 4+hours in a patient with a weak heart.
It all depends on the need of the patient, their ability to tolerate the volume, and how ill they are.

In brief: Up to 4 hours

Clemence, the typical time for transfusing blood into someone is around 2 hours.
You can extend this to 4 hours if needed.

In some special cases the unit of blood can be transfused in smaller bags for patients like newborn or elderly with CHF, in those cases each one of the bags may take up to 4 hours to transfuse.

In brief: Few minutes to 4 hr

It depends on the situation.
In a life-threatening trauma case, blood can be transfused as quickly as it can be pushed in through a large-bore iv, in just a few minutes. The usual, less emergent, blood transfusion is usually performed over 2-4 hours.
