Blood transfusions are done to replace blood lost during surgery or due to a serious injury. A transfusion also may be done if your body can't make blood properly because of an illness. During a blood transfusion, a small needle is used to insert an IV line into one of your blood vessels. Through this line, you receive healthy blood. The procedure usually takes 1 to 4 hours, depending on how much blood you need. Blood transfusions are very common. Each year, almost 5 million Americans need a blood transfusion.
Best Answer: The donor's body usually replaces the liquid part of blood (plasma) within 72 hours after giving blood. It generally takes about 4â8 weeks to regenerate the red blood cells lost during a blood donation. An iron-fortified diet plus daily iron tablets can help rebuild a donor's red blood supply. Extra: Red blood cells carry oxygen to the body's tissues and remove carbon dioxide.
