A normal blood transfusion typically involves the administration of one unit of whole blood, which is approximately 450 to 500 cc (milliliters). However, the volume can vary depending on the specific type of blood product being transfused, such as red blood cells, platelets, or plasma. It's important to follow medical guidelines and protocols for safe transfusion practices.
After an operation, many patients need a blood transfusion.

First you must have a type and screen which determines your blood type. Then the blood get cross-matched to see if it is a good fit.

There are many reason why a person may be given a blood transfusion. 6 units is a great deal even in a major surgical operation. It is also given after a major traumatic accident and with certain blood diseases.
Excess blood cells forming conditions such as polycythemia are often treated by blood letting.So also in iron poisoning.Exchange transfusion used in many disaese also involve initial blood letting and transfusion with another persons blood.As such a normal person may not have any benefits from blood letting,so dont do it for such benefit.But if a person letting blood for donation is to be encouraged as it saves life of the recipient and does not harm the normal donor.Body has remarkable power to replace lost blood quickly.
People are rarely infected with HIV through blood transfusion now. Scientists have not always known what HIV was or how to detect it. During this time, many people were infected with HIV as a result of blood transfusion. Thankfully, now every blood sample collected is tested for a variety of diseases, including HIV.
No. Hemophilia is a genetic disease. But many hemophiliacs can benefit from having them.
Transfusion of red cells or whole blood (rarely) should never be used as a hematinic, but rather to increase the oxygen carrying capacity in the recipient. Iron should be administered when the patient has decreased hemoglobin content and is stable enough (and able) to produce their own RBCs.

Some symptoms of a mild transfusion reaction from getting the wrong blood are chills, fever, dizziness, flushed skin, back pain, and the presence of blood in urine. These symptoms can manifest when a person is receiving the transfusion or shortly after. In some cases, a person also can have a severe transfusion reaction that can cause symptoms like shock, decreased blood pressure, and a rapid pulse.
