The mean Hgb increment closely approximated 1 g/dL. There was a wide variation among the patients, females experienced a greater Hgb increase than males. Allogeneic units increased Hgb more than autologous units.

People will receive a blood transfusion when there is a significant loss of blood, severe anemia, or as otherwise directed by a physician. On average, a transfusion of one pint of blood will raise hemoglobin levels by one gram. Hemoglobin is measured by grams per deciliter (100 milliliters) of whole blood.
Usually 10 g/L
Current transfusion medicine guidelines do not recommend transfusion of red cells in patients with a hemoglobin of 7 g/dl or higher or a hematocrit of 21% or higher IF their underlying medical status is stable (adequate cardiovascular/pulmonary reserves) and they are not not actively bleeding. Each 500 ml loss of whole blood is expected to decrease the partients hemoglobin by 1.0 g/dl and the hematocrit by 1-3%.
no
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.
Oh yes, blood transfusion is done with real blood, although there have been experiments with artificial blood, and sometimes blood plasma is used rather than whole blood, when there is a problem in getting the right blood type.
Whole blood is generally used when a person has lost a lot of blood. Such blood loss can be caused by injury or surgical procedures. Whole blood is given to help restore the blood volume, which is essential for maintaining blood pressure.
Most of the time whole blood is not used because the patient's medical condition can be treated with a blood component and too much whole blood can raise a recipient's blood pressure. High blood pressure can have medical side effects
For sure it can be and that is the reason why in UK leucocytes are removed from whole blood before preserving it for future transfusion.
Plasma hemoglobin and Perfluorocarbons are not true blood substitutes; hemoglobin can replace only the oxygen transport capacity of whole blood, without the coagulation aspects normally present in blood.
Most patients will not require transfusion of blood components if 500 ML of whole blood is lost. However, depending on the patients underlying medical condition and cardiovascular/respiratory reserve, even small amounts of blood loss may lead to significant reactions requiring replacement.
If you lose a lot of blood, you may need it replaced. This is called a blood transfusion. You may receive a combination of whole blood and plasma.
