A second transfusion took place, but it was unsuccessful, and the patient died. Richard Lower, an English physician, performed a similar procedure on November 23, 1667. [1] [5] He successfully transfused the blood of a lamb to a 22-year-old man. [1] In both cases, the whole blood of the lamb was directly introduced into the vein of the patient.
Banked blood during the blood transfusion process As the person receives their blood transfusion, the bag slowly empties, leaving behind blood that has clotted before it could be administered. Historically, red blood cell transfusion was considered when the hemoglobin level fell below 100g/L or hematocrit fell below 30%.
An exchange transfusion is a blood transfusion in which the patient's blood or components of it are exchanged with (replaced by) other blood or blood products. [1] The patient's blood is removed and replaced by donated blood or blood components. This exchange transfusion can be performed manually or using a machine . [2]
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...

A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood. It aims to provide an alternative to blood transfusion , which is transferring blood or blood-based products from one person into another.
In such a case, ANH can save a maximum of 1.1 packed red blood cell unit equivalent, and homologous blood transfusion is necessary to maintain H m, even if ANH is used. [citation needed] This model can be used to identify when ANH may be used for a given patient and the degree of ANH necessary to maximize that benefit. [citation needed]
