A blood transfusion is usually an immediate intervention in acute anemia situations, but it can be continued at regular intervals for long periods of time. Receiving donor blood will increase your blood's ability to carry oxygen. It is important to note that a blood transfusion is rarely needed for nutritional anemia.
During a transfusion, a needle is placed in one of your veins. A bag containing the blood product is hung on a pole nearby, and its contents are dripped slowly, intravenously (through the vein) into your bloodstream. Throughout the transfusion, your temperature, heart rate, breathing, and blood pressure are checked regularly, and you are questioned about pain, itching, or discomfort of any sort. This monitoring is most careful during the first 15 minutes of the transfusion, since most severe reactions occur early in a blood transfusion. Once the bag containing the blood product is empty, the needle in your arm is removed.
